ZENO POWER: Closes $50 Million Series B Financing

Zeno announces series b
Nucleation announces its investment in Zeno Power’s $50 Million Series B with Fund I

Nucleation is delighted to announce our participation in Zeno Power’s $50 million Series B funding round, led by Hanaco Ventures with participation from Seraphim, Balerion Space Ventures, JAWS, Vanderbilt University, RiverPark Ventures, Stage 1 Ventures, 7i Capital, Beyond Earth Ventures, and other investors.

Axios article headline and battery image.In an article released today, Axios has first reported on Zeno Power's close of this funding together with news of the company's appointment of Admiral John Richardson, USN (Ret.), former Chief of Naval Operations and Director of the Naval Nuclear Propulsion Program, to its Board of Directors. This brings the total raised by Zeno to over $70 million, following the company's Series A, which was led by Tribe Capital.

Zeno Power is working to power strategic frontiers, which include the deep ocean, the Artic and space, regions where there are prospects for commerce, strategic influence and international competition for resources. The company builds nuclear batteries, essentially radioisotope power systems, which convert the heat from nuclear "waste" materials like Strontium-90 (Sr-90) into long-duration energy sources. The demand for such power systems—by groups seeking to operate on the moon, Mars, in the Artic and deep ocean—prove the high value of many of the highly radioactive materials found in nuclear waste. Over the last three years, Zeno has secured over $60M in contracts from the U.S. Department of Defense and NASA, built and demonstrated their first nuclear prototype at Pacific Northwest National Laboratory, and secured the nuclear fuel and facilities to build their first 10+ nuclear batteries.

The company's Series B funding is expected to unlock the team's plans to:

  • Demonstrate full-scale nuclear batteries in 2026 to enable maritime and space deliveries in 2027
  • Scale their manufacturing capabilities to meet growing demand from government and commercial customers
  • Expand into seabed telecommunications, deep-sea mining for critical minerals, and commercial space markets
  • Grow our team from 65 to 100+ team members across Seattle and Washington D.C.

POWER SURGE: Report on this one-day conference

Power surge conference

An important conversation hosted by Doon Insights

Doon Insights, an investment-focused group organized by Howard Chao, convened dozens of subject-matter experts as speakers (see the list below) across many disciplines in Santa Cruz, California to address trends and issues impacting demand for and supply of energy in the coming years and decades. Energy, which is what makes today's technologically-dependent society possible, is a very large and important topic and was a lot to cover. But in an ambitious, rapid-paced one-day conference titled "POWER SURGE: Solving for Unprecedented Energy Demand," dozens of people laid out the fundamentals and discussed the key questions around both what is driving demand and how will we meet that demand. Questions tackled included:

The demand side    Demand Side

  • Why projections for US power needs now greatly exceed what would have been predicted only a couple of year ago
  • Why the exceptional needs of AI Data Centers and the electrification of diverse parts of the economy are driving energy demand
  • What are the challenges of building, financing and operating new data centers? 
  • How much more power will these new facilities require? Where will they be located and what is the attitude of utilities, state and federal government towards supporting them?  
  • How will the rapidly changing AI competitive landscape affect these power projections? Does the advent of very cheap, highly efficient, smaller SLMs, open source models and Chinese competitors mean that investors have overestimated the need for huge data centers?  
  • How will the electrification of vehicles, buildings, industry and transactions (blockchain and cryptocurrencies) further accelerate and add significant incremental power demand?
  • What are the primary challenges to meeting these power demands of these expanding use cases in the coming years and what will be the main challenges to implementation, including the need to expand the transmission capabilities of the grid?
  • Will the new administration's renewed emphasis on fossil fuels result in a slowdown in electrification? 
  • What will be the impact of the tariffs on the buildout of all these projects?
  • How will the new administration's energy policies impact all of these areas? Will we be able to unleash power generation sufficient to sustain the foreseeable economic growth while also continuing to reduce carbon emissions?

  • What are the near and longer-term challenges and solutions to the surge in power demand?
  • Will growing renewables and batteries be sufficient?
  • Will fossil fuels experience a resurgence, with all that drilling?
  • Will the sexiest and biggest solutions—nuclear fission and fusion—be coming on stream faster than most people believe?
  • What are the short, medium and long-term prospects for these new technologies?
  • Will the "privatization" of nuclear innovation and the prevalence of an industry being led by fast-moving private companies, pleasantly surprise us with their speed to market?
  • What will be the near-term and longer-term mix of energy solutions?
  • How will a patchwork of revamped legacy technologies, including fuel cells, wind, solar, distributed generation, energy storage, energy time-of-use shifting and other behind-the-meter solutions help in the short-term? 
  • How are advancements in small modular nuclear reactors (SMRs), which offer enhanced safety features, reduced construction times, and the flexibility to be deployed in diverse locations, going to contribute?  
  • Given that major technology companies like Google and Amazon are investing in SMRs to power their expansive data centers, how will this accelerate commercialization?
  • Fusion energy—which is experiencing a wave of breakthroughs, with multiple companies and research initiatives racing to develop and commercialize multiple technologies, such as high-temperature superconductors, improved plasma confinement techniques, and novel neutron flux applications—is beginning to generate revenues but has yet to complete a power-generating reactor design. Will the new administration help accelerate progress towards practical fusion power with pilot plants within the decade or is this game-changing technology still decades away?

The Nuclear Option

Screenshot 2025 05 04 at 8.23.42 amValerie Gardner, Nucleation's managing partner, moderated the day's fission panel, called "The Nuclear Option: Generation IV and Small Modular Reactors," which looked at the role of fission innovation and the coming wave of small, modular reactors (SMRs), that were poised to bring nuclear power into the 21st century. She and her panelists, Leah Crider from Westinghouse (seated on the left), representing the eVinci design, and Clayton Scott from NuScale Power (in the center), which has the first NRC-certified advanced fission design, discussed how and why next-generation nuclear will be the ideal clean energy solution that few think is possible.

While the Fission panel had a full 45 minutes (and probably went over-time) to cover a lot of ground, including reviewing nuclear's status as a major source of today's clean energy, the fact that nuclear is turning into a "technology" product that can be manufactured in factories and shipped to locations, and how a growing assortment of energy buyers like Google, Amazon and Dow Chemical see advanced nuclear as solving their energy needs better than other solutions, because the subject matter was so expansive, Valerie and her panel were able to cover many but definitely not all of the important points. Nevertheless, the fact that this conference's supply-side conversation included nuclear fission at all was a huge victory. This inclusion reflects the fact that nuclear energy is no longer seen as the taboo topic it was long deemed to be, at least up until the last couple of years. For too long, nuclear fission was excluded and no one considered it a vital part of the clean energy solution set. But times have changed and especially among investors looking to understand key long-term trends and be able to invest into them at an early stage.

According to Howard Chao, each panel of the conference, by design, was too short, leaving a lot of unfinished conversations. Nucleation Capital was honored to have been included in this discussion and we look forward to continuing to see interest in advanced nuclear broaden.

Assessing the Election’s Impacts on Nuclear

By Valerie Gardner, Nucleation Capital Managing Partner

Kh v dt.png

Presidential elections are always important and this year's election is widely considered particularly critical and unusual.  There are vast differences of opinion on matters of great national importance—from voting rights and health policies to international relations and national security policies. Less well litigated is where these candidates stand on matters of energy security, the energy transition and future deployments of both traditional and advanced nuclear power. How will the differences in character, knowledge and respect for facts, science and experts play out on U.S. policies towards nuclear power?  Based upon various sources, it appears that the election will have a significant impact. For those still making up their minds, this summary assessment may help clarify how numerous pundits view these differences.

Summary

Nuclear energy has enjoyed enduring bipartisan support across both Democratic and Republican administrations for years now. The Congress has passed, with overwhelming bipartisan majorities, bills aimed at modernizing and accelerating commercialization of new nuclear.

Nevertheless, in 2024, the two presidential candidates bring potentially unconventional approaches that may differ from the standard positions of their respective parties. Republicans have long valued America's nuclear capacity and have seen the need for the US to maintain leadership to boost both national security and to expand our ability to export our technologies. They recognize that the U.S. needs to counter the geopolitical influence of adversaries like Russia and China which are offering to help developing nations with nuclear power as a means of increasing their influence within those countries.

Democrats have also, if more recently, come around to support nuclear. Both the Obama White House and the Biden Administration have provided broad support for the industry and particularly for the acceleration of next-generation nuclear technologies and American leadership in the energy transition. Front and center of their support is the recognition that nuclear power is a critical, differentiated component of a reliable, 24/7 low-carbon energy grid. They support its expansion primarily as a mechanism to meet growing energy needs and fortify grid reliability while reducing carbon emissions and addressing climate change, in tandem with renewables.

The question then of which candidate is more likely to support the continued acceleration of nuclear power is thus wrapped up with policies relating to energy security, fossil fuels, geopolitical competition with Russia and China, and support for addressing climate change. The Inflation Reduction Act passed in 2022 and signed by President Biden marked the Congress' single largest investment in the economy, energy security and climate change and is widely seen as the most important piece of climate legislation ever passed. It simultaneously rebuilds the U.S. industrial capabilities while incentivizing the growth of clean energy technologies including domestic nuclear power. It is already making an enormous and beneficial impact on the U.S. nuclear indsutry.

Kamala Harris, while possibly more progressive than Biden, has shown her support for Biden's approach to incentivizing the clean energy transition through the IRA, Biden's signature piece of climate legislation, which has received staunch support from industry. She is unlikely to make many if any changes to the IRA's clean energy technology-neutral Investment Tax Credits and Production Tax Credits or reduce the billions in loan guarantees available through the Loan Program Office, which have already stimulated significant investment in protecting and restarting existing reactors.

Because of Biden’s Infrastructure Investment & Jobs Act’s Civil Nuclear Credit program, California is proceeding with the relicensing of Diablo Canyon, Holtec has chosen to restart, rather than decommission, Michigan’s Palisades nuclear power plant, Constellation has inked a deal with Microsoft to restart Three Mile Island Unit 2, and NextEra Energy is actively considering the restart of Duane Arnold. Meanwhile, Google has signed a deal to buy power from advanced nuclear reactors being designed by Kairos Power and Amazon has signed a similar deal with X-energy, marking the first corporate purchases of next-generation nuclear, thanks to highly motivating tax and financing incentives available through the IRA and LPO.

Harris is clearly committed to addressing climate change. There is no evidence that she rejects the clean energy tech-agnostic approach developed during her term as Vice President, which levels the playing field for nuclear energy as a clean energy source. Harris recognizes the geopolitical importance of America's ability to compete with Russia to produce our own nuclear fuel supply and to provide nuclear technologies to developing nations seeking to build their clean energy capacity but wanting to remain free of Russian or Chinese influence.

In contrast, Donald Trump has repeatedly called climate change a "hoax," and/or a good thing and cares little about reducing U.S. or global emissions. He previously walked away from the Paris accord and would likely try to repeal, roll back or dilute the IRA. He's publicly allied himself with the fossil fuel industry and—in exchange for donations—has promised to roll back EPA regulations and help them "drill, drill, drill."

There is almost no doubt that Trump would step the U.S. away from its leadership role on climate and this time, that may mean reversing the U.S.'s pledge to triple the amount of nuclear power. This would seriously undermine both the U.S. nuclear industry's momentum to expand to meet growing demand as well as international progress. Given Trump’s overt courting of Putin, he may be disinclined to rebuild the U.S.'s nuclear fuel production capacity or seek to accelerate or support American efforts to build nuclear projects internationally in competition with Russia.

None of this would be good for nuclear power. Any potential efforts to rollback the IRA would slow restoration, development and deployment of reactors. Boosting the fossil fuel industry, whether through supporting expanded access to federal land or price manipulation to improve profitability would have severe impacts on the energy transition. Trump's recent acknowledgement that he didn't believe nuclear was safe also belies the stated "commitment" to nuclear energy expressed by his surrogates and gives considerable fodder to those who persist in opposing nuclear. His shoot-from-the-hip, truth-be-damned leadership style and embrace of conspiracy theorists, contrasts starkly with Harris' stated willingness to consult with scientific experts and even give those who disagree with her a seat at the table.

In sumary, Trump's likely propensity to undermine the IRA, oppose climate action and backtrack on US pledges to triple nuclear, his support for expanding fossil fuel production and his continued disdain for science and technical experts, poses extreme risks to the momentum generated within the nuclear sector over the last few years. Trump's ignorance of nuclear energy's exceptional safety performance make him unlikely to provide Oval Office leadership either to the industry or the NRC in support of the bipartisan ADVANCE Act, signed into law by Biden.

In contrast, a Harris Administration would likely remain on the current climate glideslope for leadership, technology-neutral funding and the U.S.'s nuclear tripling momentum as stimulated by the Biden Administration. It may be that a Harris Administration does not prioritize nuclear's growth or add billions in new accelerants as Biden has done, but she will not try to trash it. Having been briefed by senior energy advisors over the last four years about the importance of nuclear, she is well-informed and understands the importance of Biden's initiatives for addressing climate.

Based on this analysis, those who support an expansion of nuclear power and enduring progress towards transitioning away from fossil fuels should thus prefer to see Harris elected, rather than Trump, and the existing policies continued.

Dr. Hansen warning humanity to get its act together, deploy renewables and nuclear

Dr. James Hansen's year-end update contains an admonishment right in the title, "A Miracle Will Occur" Is Not Sensible Climate Policy."  Those who have followed his work and his typically well-tempered writing will recognize this as a very strong indictment of what we've not done to date to address climate change. This is, for this mild-mannered scientist, the equivalent of "Hey Guys, Get your S _  _ T together!"

Dr. Hansen proceeds to call "bunk" on the assertions from both the COP 28 Chairman and the UN Secretary General who imply that the goal of keeping temperature rise to below 1.5°C is still feasible. According to Dr. Hansen, the already banked warming will take us beyond 2.0°C "if policy is limited to emission reductions and plausible CO2 removal." In other words, he makes it clear that this is now merely wishful thinking and does not reflect a realistic understanding of the way that emissions released create future warming, which he calls "Global Warming in the Pipeline" and describes in the linked paper.

The only realistic approach is to take true climate analysis that is informed by knowledge of the warming "forcing" effects and to use that to drive decisions about policy options. If we can possibly use the next several years to define and commence more effective policies and courses of action, then there is a modicum of a chance that we can still save the future for our young people. If this isn't a bomb of an alarm, it would be hard to say what else would be, especially because the IPCC has made it very clear that major ecosystems, starting with coral reefs and then, therefore, all marine life, will be threatened with substantial (90%) collapse by 1.5°C  and with 100% by 2°C.

Unfortunately, climate science is complicated and most people don't have a good understanding of the "human-made forcings that are driving Earth's climate away from the relatively stable climate of the Holocene (approximately the past 10,000 years.)" Even if they could grasp the implications about climate science from the graphs that Dr. Hansen and his team provide, very few are even reading Hansen's work. These graphs are very scary but clearly they are not being used as the basis for policy discussions by either politicians, government agencies (like the EPA), or by leading environmental groups and that is likely the primary reason why many people are still arguing about renewables versus nuclear power, thinking they have a certain luxury of time, rather than saying "Renewables and nuclear, YES!"

For his part, Dr. Hansen doesn't make it as easy as he could for those with less expertise in climate science. He spends a lot of effort discussing two major climate forcings: greenhouse gases (GHGs) and aerosols (fine airborne particles), which in fact have opposing forcings. But then goes into detail on many other related forcings. This level of detail may provide a more scientifically accurate picture of what is going on but it makes for much sparser readership. Clearly, there are many different kinds of feedback loops, including how the aerosols impact cloud formation, albedo effects and also the way the ocean absorbs a considerable amount of the warming that is happening to our climate. It's important that he understands these effects but it takes considerable sifting work to get to the point that what it all adds up to is that there is much more warming that has occurred than what we are actually now experiencing, so in fact, the effect of warming will be accelerate and we're now seeing this.

Even for those of us who finding climate science fascinating, this 14-page paper is incredibly dense and gets relatively badly bogged down with details on things like cloud forcings, albedo changes, reviewing differences between expected temperatures and real world measurements, catching up with a 40-year old mystery having to do with the last glacial maximum and describing the impacts of an "experiment" that occurred when the International Maritime Organization limited sulfur content in ship fuel and the variability introduced by El Nino and La Nina events.  The bottom line of quite extensive discussion that few will wade through, is that global warming is now accelerating. This is very important but definitely buried. The key graphic of the whole paper depicts this acceleration.

On page 7, we finally get to the implications of global warming acceleration.  As shown in the above graph, were the warming happening at a steady rate, we'd be on the green dotted line. Instead, we are veering off into the yellow zone of accelerated warming, which means that we'll "exceed the 1.5°C mark within the next few months and reach a level far above 1.5C by May 2024."

Hansen, while recognizing that there could be some up and down based upon El Nino and La Nina effects, believes that the baked in energy imbalance already "in the pipeline" means that it does not serve anybody's interests to "wait a decade to declare that the 1.5°C limit has been breached." In summary, Hansen argues that, "unless purposeful actions are taken to reduce our present extraordinary planetary energy imbalance," the 2°C global warming limit will also be breached.

By its very nature of having a delayed, baked-in response, human-made climate change makes this an intergenerational issue. What we have done in the past is already having consequences but what we do today and going forward will mostly impact the next generation for better or worse.

To his credit, Hansen dives yet again into Climate Policy, unlike most other scientists. This has been long been a huge source of frustration for him and you can almost see him stomping on his own hat, in his anger and impatience with the political processes that have thwarted action. First he reviews just what makes solving cilmate extra hard, starting with the fact that the principal source of GHGs is fossil fuels, which are in his words "extremely beneficial to humanity."  They have raised starndards of living worldwide and still provide 80% of the world's energy. "Fossil fuels are readily available, so the world will not give up their benefits without equal or better alternatives."  Because of this conundrum, we are near a point of no return, where extreme consequences can spiral out of humanity's control.

Dr. Hansen has been a first-hand witness to humanity's failure to act over the last 35 years or so and his exasperation with that and his desperation to communicate to those in power about our increasingly limited options is abundantly clear. He's been advising governments around the world on possible approaches with little of the urgent response that is warranted.  He delves into some of these details but then finally hones on in the three actions that are required to successfully address climate and achieve the bright future we desire for our children.

The first is a near-global carbon tax or fee.  It is the sine qua non required to address the "tragedy of the commons" problem" wherein fossil fuels waste products can be dumpted in the atmosphere for free.  There can be a range of approaches, yet something that penalizes those dumping GHGs is required to be enacted globally. A corollary to a carbon fee is a "clean energy portfolio standard," with government policies that are far more supportive of nuclear power.

The second major policy requirement, is the need for the West to cooperate with and support the clean energy needs of emerging and developing nations. There are economic imbalances with developed nations having caused the past emissions but emerging nations increasingly being the driver of future emissions:

The clear need is to replace the world’s huge fossil fuel energy system with clean energies,
which likely would include a combination of “renewables” and nuclear power. Even if the
renewables provide most of the energy, engineering and economic analyses indicate that
global nuclear power probably needs to increase by a factor of 2-4 to provide baseload power
to complement intermittent renewable energy, especially given growing demands of China,
India and other emerging economies. The scale of China’s energy needs makes it feasible to drive down the costs of renewables and nuclear power below the cost of fossil fuels.

Lastly, Dr. Hansen proposes that "a multitude of actions are required within less than a decade to reduce and even reverse Earth’s energy imbalance for the sake of minimizing the enormous ongoing geoengineering of the planet; specifically, we will need to cool the planet to avoid consequences for young people that all people would find unconscionable."

Pronuclear Advocates & Allies

About the Pronuclear Climate Movement

Pronuclear climate advocacy has been around for only about a decade but it has grown rapidly. It consists mostly of young people who understand the urgency of the climate crisis and recognize that nuclear energy is a way to help us transition away from fossil fuels. They believe we should protect existing nuclear plants providing large amounts of clean energy and build more.  They have worked to save plants slated for premature closure, like Diablo Canyon in California and Palisades in Michigan. And they continue to work to save existing nuclear plants around the world, reform clean energy policies that exclude nuclear and favor renewables and educate the public about the benefits of nuclear. This is a reflection of growing support for nuclear power in general and a recognition that the goal of the climate movement is to prioritize retirenent of fossil fuel plants—whose massive volume of waste emissions is forcing the warming of our planet—not shut nuclear, whose waste hurts no one and is actually a valuable future energy resource.

The pronuclear movement consists of mostly smaller, independent groups that do grassroots organizing around a theme, such as working to prevent the closure of a local nuclear power plant. Fortunately, many of these groups are interconnected yielding suprisingly effective coordination when it matters. Many also have broader goals, such as the Climate Coalition, which aims to strengthen the climate movement overall by uniting climate activists of all stripes in support of an "all-of-the-above" nuclear-inclusive approach to clean energy. These groups can use your help.

How to Support the Pronuclear Climate Movement

For those who want to support nuclear power in addition to (or in lieu of) investing in next-generation technologies through Nucleation Capital, we provide the following recommendations:

  1. Stop Supporting Anti-Nuclear Organization: Stop sending donations to the Sierra Club, NRDC, 350.org, Friends of the Earth, League of Conservation Voters, or Greenpeace. These large NGOs remain staunchly anti-nuclear and that is primarily what is dividing the climate movement.
  2. Urge your NGO to Prioritize Climate: If you have been a member or supporter of an anti-nuclear environmental group, let them know you don't support their anti-nuclear positions—which are contrary to their supposed efforts to solve climate—and won't support them until they acknowledge the value of nuclear energy for combating carbon emissions.
  3. Actively Support Pronuclear Groups:  Throw your support behind one or more of the pronuclear nonprofits that are working hard to save existing power plants and to advocate for nuclear power. We have curated the following lists to help you find organizations or individuals to support.

Nucleation's Top 5 Pronuclear Organizations

1. CALIFORNIANS FOR GREEN NUCLEAR POWER

Californians for Green Nuclear Power, led by Dr. Gene Nelson, has  been a driving force for political accountability and responsible energy decision-making in California. Shedding light on sweetheart backroom political deals being cut by Governor Jerry Brown that were contrary to the public interest, CGNP filed suits and/or petitioned to become a party to CPUC and FERC proceedings. CGNP's work as an intervenor has been instrumental in helping to save Diablo Canyon. CGNP's in depth research continues to pose obstacles to efforts to overturn the California legislature's extension approval are being filed.

2. MOTHERS FOR NUCLEAR

Mothers for Nuclear was created on Earth Day 2016 by the power team of San Luis Obispo-based Heather Hoff and Kristin Zaitz, two moms to better represent the voices of women and mothers in support of Diablo Canyon and nuclear energy in general. Coordination with Californians for Green Nuclear Power, Save Clean Energy and many other groups enabled Governor Newsom to respond to strong public pressure to save Diablo Canyon when appealing to the California Legislature. Progressive women remain predominantly opposed to nuclear power, but Mothers for Nuclear have begun to rebuild the social norm of women being pronuclear. (Donations can be made online. EIN: 81-3349003)

3. GENERATION ATOMIC

Generation Atomic was created by Eric Meyers to represent the voices of younger generations and empower them to express support for nuclear in every type of venue and forum where discussions of how solve climate change is happening. The group creates fun, engaging, public actions in an effort to safeguard our future by championing the cause for nuclear energy. Not only do they use research, communication and relationship-building to advocate for nuclear, their actions typically involve dancing, singing, inflatable costumes and humor to inspire, empower and engage youth and defang anti-nuclear wrath. Operatic nuclear arias, anyone? (Donations can be made online. EIN: 81-4500446)

4. THORIUM ENERGY ALLIANCE

Thorium Energy Alliance was started in 2006 by John Kutsch to bring together scientists and energy experts who believe that thorium should be recognized as a high-value nuclear fuel and not treated as waste. Thorium is far more abundant and less radioactive than uranium, yet was rejected early on in the development of nuclear fuel. This despite evidence that the use of thorium is feasible and can be highly cost-effective. TEA works to raise awareness about thorium and hosts conferences, posts videos and serves as a central organizing and educational entity for many nuclear advocates, which history was beautifully captured in the Frankie Fenton documentary film "Atomic Hope." (Donations of cash or cars can be made online.)

5. CLIMATE COALITION

Climate Coalition was founded in 2016 by Valerie Gardner and a group of technology-oriented climate activists who recognized how much stronger the climate movement would be if climate advocates were not fighting amongst themselves. Unfortunately, activists who support renewables often ardently oppose nuclear power and vice versa. Climate Coalition views this internecine conflict as the primary reason why global effort to transition to 100% clean energy systems are delayed everywhere. So long as this fighting continues, demand for and investment in fossil fuels will remain strong. Join Climate Coalition to show your support of unity against carbon emissions.

A New Oppenheimer Moment

We've had a resurgence of interest in and conversation about nuclear energy since the release at the end of April of Oliver Stone's exceptional documentary, Nuclear Now. But Stone's historic film, much like Robert Stone's Pandora's Promise and Dave Schumacher's The New Fire, before it, suffers from the endemic unpopularity of documentaries. People don't flock to theaters to see them. Which made (what was called) "Barbenheimer,"  the culturally clashing concurrence of opening nights for Greta Gerwig's very pink Barbie movie and Christopher Nolan's explosive Oppenheimer so different. Theaters were packed. People went to see them as double-features. The press had a field day for a week and both films exceeded box-office expectations, providing welcome relief for movie theaters everywhere.

The public is, as a result, reacquainted with J. Robert Oppenheimer (JRO to those who knew him) and his tortured if heroic role in leading the U.S.'s war time emergency program, dubbed "The Manhattan Project," to a successful conclusion: creation of the first atomic bomb. Whether or not this crowning achievement by the secretive project—that recruited the world's top physicists, engineers and scientific minds to Los Alamos, a remote area in New Mexico—and let the atomic genie out of bottle was a net positive or a net negative, may still be debated. But now that it has, we must rely on our ability to self-regulate the use of this technology for good, as JRO understood so well.

We are now in the throes of sorting out how best to limit nuclear bombs but expand the beneficial uses of atomic tech for energy, industry, agriculture and medicine. Which is why we were so pleased to have been connected with Charles Oppenheimer some weeks ago and to have been invited to participate in the Oppenheimer Exchanges, a day long event bringing together leadership from within the DOE's National Labs and a few business groups, orchestrated to coincide with opening night for the Oppenheimer film. Fortunately, this included tickets to the San Francisco premiere at the Metreon iMax Theatre and a brief pre-screening conversation between younger members of the Oppenheimer family, who provided some perspective on the family's legacy and ongoing initiatives. 

For many of us, this was an eye-opening discussion. It was just in December of 2022, that the DOE finally restored Oppenheimer’s long lost—but still widely lauded reputation—with an order vacating the Atomic Energy Commission's 1954 decision to revoke JRO's security clearance. While largely symbollic, since JRO died in 1967, the DOE's order, and Secretary Granholm's Statement about it, addressed and began to reverse the damage that had been done to the Oppenheimer name, through what the DOE called a "flawed" process.

In 1954, the Atomic Energy Commission revoked Dr. Oppenheimer’s security clearance through a flawed process that violated the Commission’s own regulations. As time has passed, more evidence has come to light of the bias and unfairness of the process that Dr. Oppenheimer was subjected to while the evidence of his loyalty and love of country have only been further affirmed. The Atomic Energy Commission even selected Dr. Oppenheimer in 1963 for its prestigious Enrico Fermi Award citing his “scientific and administrative leadership not only in the development of the atomic bomb, but also in establishing the groundwork for the many peaceful applications of atomic energy.” 

Among scientists and those who knew Oppenheimer's legacy, vindication had already begun as far back as 1963, when the Atomic Energy Commission selected Oppenheimer for the prestigious Enrico Fermi Award for his "scientific and administrative leadership not only in the development of the atomic bomb, but also in establishing the groundwork fo rthe many peaceful applications of atomic energy."

Then, in 2017, the DOE recognized JRO with the creation of the Oppenheimer Science and Energy Leadership Program, which was designed to support early and mid-career scientists and engineers to "carry on [RJO's] legacy of science serving society."

This DOE program has now graduated multiple cohorts. Many of these alumni gathered in San Francisco to discuss the Oppenheimer legacy and explore relevant topics, in particular the need for science and scientists to rise to the challenge of solving global crises with technology. Oppenheimer's leadership example is a model by which the scientific community can organize itself to tackle problems, such as climate change.  Given how badly we are doing responding to the threat posed by climate change, this is a very welcome concept.

 The Oppenheimer Science and Energy Leadership Program (OSELP) run by the DOE is “the premier leadership development program of the national Laboratory Directors’ Council, which comprises the leadership of all 17 National Labs.  The program exposes emerging leaders to the singular breadth, diversity and complexity of the National Labs and their partners in government, industry, and academia. OSELP represents a collective commitment from all 17 DOE labs to cultivate the leaders needed to sustain long-term impacts throughout the complex. Out of the OSELP has grown an alumni group now called the Oppenheimer Leadership Network, who are those who have been through the OSELP program.  The OLN is the formal network of ESELP alumni to collaboratively engage on strategic issues and produce deliverables that address major organizational, policy, scientific or other challenges within the National Labs’ mission space. We were pleased to meet many members of the OLN at the event. Now the Oppenheimer family has a new vision.  They are aiming to develop several initiatives, under the banner of The Oppenheimer Project, whose mission is to promote and advocate for solutions to mitigate the risks posed by technological development.   1) Promote JRO’s legacy and encourage scientific leaders to discuss and address today’s existential threats.2) Advocate and educate about nuclear energy, for increased cooperation on energy and decreased threats of weapons.3) Invest in the energy transition to carbon-free energy sources including nuclear energy. Already, Charles Oppenheimer, JRO's grandson, has come out strongly for nuclear power in a Time Magazine Ideas article, entitled Nuclear Energy's Moment Has Come, published May 11, 2023. In it, Charles calls for a "Manhattan Project" for carbon-free energy production.

In addition to having the support of the younger members of the Oppenheimer family, The Oppenheimer Project has received the support of Lynn Orr, a former Under Secretary for Science and Energy at the DOE and now at Stanford University, and Dr. Larry Brilliant, a physician, epidemiologist and senior counselor at the Skoll Foundation, as advisers. There are now some dozens of graduates of the OSELP and OLN members who could also participate. Given how poorly we are doing mounting the appropriate response to the threat from continued emissions, extending Oppenheimer's inimitable complex project management legacy to tackling this new global challenge has the potential to be significant development in the fight against climate change.

Dire warnings from Dr. Hansen and team

Those who receive Dr. James Hansen's occasional newsletter from his Climate Science, Awareness and Solutions team, will have seen some dire reports before. Still, nothing we have seen is quite as unimaginable or alarming as learning that global warming is happening at the equivalent of 750,000 exploding Hiroshima atomic bombs in our atmosphere per day, every day. From burning fossil fuels. That's a lot of warming . . . !

No one likes to think about nuclear bombs. Their very bad reputation already negatively impacts how people think about nuclear energy (even though bombs are designed to explode and nuclear energy is designed so it can't explode). But in this case, Hansen's comparison really helps. Not just as to the scale of the warming problem but as to level of threat.

Earth's Energy Imbalance chart and climate response.

Fig. 1: 12-month running-mean of Earth’s energy imbalance, based on CERES satellite data for EEI change normalized to 0.71 W/m2 mean for July 2005 – June 2015 based on in situ data.

In today's newsletter, Earth's Energy Imbalance and Climate Response Time, Hansen and team review findings recently detailed in a newly issued report called Global Warming in the Pipeline. From this report we learn that there is a lot more solar energy being absorbed by our planet than is being lost through heat radiation out into space. As they explain, the heat budget of our planet is badly out of wack. There is far more energy coming into our atmosphere than going out. As though we have put an "extra blanket" on the planet, our emissions trap heat and are causing excess warming. Dr. Hansen frames this massive experiment as “human-made geoengineering of Earth’s climate.” He writes:

Earth's Energy Imbalance (EEI) varies from year-to-year (Fig. 1), largely because global cloud amount varies with weather and ocean dynamics, but averaged over several years, EEI tells us what is needed to stabilize climate.[4] When [Dr. Hansen] gave a TED talk 10 years ago, EEI was about 0.6 W/m2, averaged over six years (that may not sound like much, but it equals the energy in 400,000 Hiroshima atomic bombs per day, every day). Now, it appears, EEI has approximately doubled, to more than 1 W/m2. [Emphasis added.] The reasons, discussed in our paper, mainly being increased growth rate of greenhouse gases (GHGs) and a reduction of human-made aerosols (fine particles in the air that reflect sunlight and cool the planet).

It appears that Dr. Hansen's 2012 TEDTalk, Why I must speak out about climate change, explained all these phenomena to us a full decade ago. So, in fact, his recent report is just providing us with an update on how little we have done to address the problem and thus how much worse things are. It is clear, we have not listened to him.

Dr. James Hansen's 2012 TEDTalk

In ten years, the amount of forced warming of our planet has nearly doubled and this is not a good thing.

So why has humanity failed to take the requisite actions to stabilize the climate? In characteristic understatement, we’re told it’s because of the climate’s delayed response. In other words, heat applied to oceans and ice sheets will still take a while to fully warm or melt them. Not only do the world’s oceans contain 270 times as much mass as the atmosphere, but water also needs 4 times as much energy as air to raise each unit of mass a degree in temperature. This provides a lag that allows global air temperatures to seem more normal than they really are. Without that lag, we’d likely have acted more aggressively to limit the heating. We’re just not fully experiencing how bad it really is. The good news: the climate’s delayed response gives us a little more time to take meaningful action, before we have so much disruption from our overheated world, that societies break down.

Dan Miller, a co-founder of the venture capital firm, Roda Group and a leading proponent of climate action, took time to review the entire 48 page  Global Warming in the Pipeline paper submitted by Hansen and 14 co-authors. He summarized its findings as follows:

1. The Earth Climate Sensitivity (ECS) — the Earth’s short-term response to a CO2 doubling — is higher than previously assumed. Most scientists said it was ~3ºC, but Hansen et al now say it is 4ºC or more based on paleoclimate data. This means there is more warming “in the pipeline” than previously assumed. 2. While humans have increased atmospheric CO2 by 50% since the industrial revolution, the actual climate forcing from all the added greenhouse gases is now ~4W/m^2, which is equivalent to a doubling of CO2 (i.e., CO2e (including all greenhouse gases, not just CO2) is about 560 ppm). 3. Part of the current warming has been hidden by human-made particulate air pollution (aerosols), mainly sulfur. When North America and Europe started to reduce emissions after the introduction of clean air acts in the 1970's, regional and global warming became more pronounced. In the past decades China and global shipping slashed sulfur emissions through cleaner fuels and sulfur filter systems ('scrubbers'). There are clear signals from ground, ocean and satellite based observations that the rate of global warming has recently doubled, which needs to be taken into account in risk assessments. 4. Assuming today’s forcing (4 W/m^2) stabilizes and human-made aerosols are eliminated, when all feedbacks — including “long-term” feedbacks — play out, we are on track for about 10ºC warming and 6~7ºC if aerosols stay at today’s levels. This is a “scenario” and we still control our future, though we are on track to increase climate forcing from today’s 4 W/m^2. 5. If greenhouse gas forcings keeps growing at the current rate, it could match the level PETM mass extinction within a century. We are increasing climate forcing 20X faster than in the PETM so “long-term” feedbacks won’t take as long as in the paleo record (though some feedbacks will still be much longer than a human lifetime). 6. The paper concludes that we must: (a) implement a carbon fee and border duty (Fee and Dividend); (b) "human-made geoengineering of Earth’s climate must be rapidly phased out,” i.e., we must stop emitting greenhouse gases, remove CO2 from the atmosphere, and research and implement safe solar radiation management to counter the massive geoengineering experiment we are currently running; and (c) we must improve international cooperation to allow the developing world to grow using clean energy. 7. A companion paper will be coming out that addresses the near-term shutdown of the AMOC and associated “multi-meter” sea level rise on a century timescale.

Dan Miller runs a Clubhouse group called Climate Chat. Following the release of Hansen's report, he interviewed Leon Simons, a co-author of the paper, about their findings and the implications. It was a 2.5 hour conversation.  It's not a happy topic but Dan, at least, is willing to confront the hard truths, in this case, that we must act immediately to address the climate crisis.

Part of the hard truth that is increasingly unavoidable, has to do with solutions. Once again, Dr. Hansen recognized the dilemma we have with respect to our options for solutions quite a long time ago: namely that we cannot realistically let go of fossil fuels without finding good alternatives, and the “best candidate is nuclear energy." Here he is discussing this in a 2013 interview:

Even though nuclear energy could dramatically help us alleviate emissions from fossil fuels, many people, including many smart investors, find the idea of proactively supporting nuclear power uncomfortable. They fear and loathe nuclear bombs—rightfully so—and can't emotionally separate those feelings enough to accept that there are compelling benefits from energy achieved by a related technology. Some just love "renewables," which generate energy from free wind and free sun. The costs of installing these have come way down and they are extremely popular, so what's not to like?

Nuclear, in contrast, is very hard to like.  It's so complicated and hard for people to understand, plus it's fraught with scary meltdown scenarios, exclusion zones and radioactive waste. Beside, we know that it's expensive and takes a long time to build, so with solid reasons like that to reject it, why risk putting one's own environmental credibility and "green" loyalty in question by supporting it, since it's already too unpopular to succeed, right?

This type of thinking has made nuclear power, quite likely the best solution we have for eliminating dependence on fossil fuels, easy to either ignore or outright reject. And this might have been the end of the story except for the inconvenient fact that wind and solar are not doing the job of reducing emissions.

It turns out that people not only want but societies need and demand reliable energy.  Even with cheap renewables, fossil fuel usage continues to expand. Because renewables are weather-dependent and the weather doesn't always cooperate. Which is, in turn, why more people are again revisiting the possibility of using nuclear power, because the alternative is natural gas.  This spurred Dan Miller to invite Carl Page, founder of the Anthropocene Institute, into the Climate Chat Clubhouse to explore these issues and discuss why public support for nuclear power has dramatically increased.

It seems Russia's attack of Ukraine followed by energy scarcity elevated global appreciation of several critical facets of energy systems beyond mere price. People woke up to the fact that energy supply security, grid reliability, energy price stability, climate resilience and limiting carbon are all important. Europe's dependence on Russian natural gas and now a war-induced energy crisis has re-focused the world's spotlight on nuclear energy—the only energy solution that addresses all of these critical energy needs. Germany, a nation deeply committed to nuclear phase-out, chose to delay the closures of its last nuclear power plants, rather than risk worsening their energy crisis. California choose to extend the life of Diablo Canyon for similar reasons.

Well maybe not shutting down existing plants makes sense, you might be thinking. But isn't it true that building new nuclear is too expensive and takes too long? The answer is not necessarily. Although Gen III nuclear power plant construction experiences have been mixed, with many in that class greatly delayed and vastly over-budget, a few of these Gen III plants have been built on time and in budget and nearly all are finally being completed. These are newer, safer light water designs and the learning process on those new designs has begun. Which means that costs of new builds can come down, if they get proper support. The question now for the industry and the world, is whether we are going to build on that construction knowledge to improve on past performance or abandon it.

Additionally, there's been movement in a whole new direction for nuclear technology: that of innovation.  Gen IV nuclear, or what many call advanced nuclear and next-generation nuclear, are innovative new designs on the cusp of commercialization. A new crop of developers are working to reimagine nuclear without water cooling. These designs largely rely on  physics for cooling, rather than muscular engineering. This reduces the need for back-up safety systems and redefines how small and how quickly nuclear can be built.

Next-gen is now widely expected to be smaller, modular, manufactured and constructed in a period of months and will be well-suited for use by corporate and industrial sites, college campuses, data centers, district heating systems and remote villages around the world. These advanced fission designs are engineering evolutions of previously demonstrated technologies such as molten salt, high-temperature gas and liquid metal-cooled reactors that do not require scientific discovery or breakthroughs. Fusion, which is developing the potential of magnetic confinement, inertial confinement and even metallic lattice confinement (formerly called "cold fusion") to generate massive amounts of carbon-free energy, still requires significant scientific breakthroughs but they also seeing progress and are widely expected to be ready to serve energy needs by mid-century.

[Click image to learn more about why Dr. Hansen and other scientists are suing the EPA.]

The question now is, will this growing global support for nuclear energy and the efforts of innovators to redesign nuclear for the 21st century enable us to meet our urgent climate goals?  Can we build nuclear faster while steadily reducing costs? Or will lingering antinuclear prejudice induce an investor delayed response that prevents construction of new Gen III designs and commercialization of a range of Gen IV designs?

The answer to that question will determine whether or not humanity meets or misses our very limited window to eliminate fossil fuels emissions by 2050. This is why we applaud the growing investor enthusiasm for building existing commercially-viable Gen III nuclear plants, as well as investing in the further development of innovative Gen IV designs, including fusion. We need them all if we are to have any hope of supplanting the 100 million barrels of oil burned every day and the 80% of electricity powered by coal and gas before it is too late.

According to Dr. Hansen, it is already very late and our climate situation is frighteningly dire. People need to act with urgency and purpose on climate: we can no longer afford delay. What we decide to do to move off the wrong path that we have been on up until now will set our course, perhaps permanently. We need good alternatives to fossil fuels. Nuclear power may not be environmentalists' or investors' first choice but it has decades of proven efficacy and safety. Best of all, current innovations hold the promise of being able to scale rapidly to serve the world's urgent energy needs.

Those who invest wisely into this risky "contrarian" area may ultimately reap the reward of seeing their investments succeed. If they do, it means they will have helped displace fossil fuel as the energy of choice and provided a compelling clean energy alternative. And for that, there could well be extraordinary returns.  There are plenty of risks for sure but, as it looks now, the risks of not investing in the solutions that can reduce emissions could well be far worse.

Hansen and team have  recently detailed new warnings and updated data in a newly issued report called Global Warming in the Pipeline, which has been submitted to Oxford Open Climate Change for publication. Read more of the history of Dr. James Hansen's research into the heating effect of CO2 in the atmosphere.  In August 1981, the New York Times published Study finds warming trend that could raise Sea Level, a report by Walter Sullivan about the study Dr. Hansen and six colleagues wrote which revealed the risk of sea level rise from global warming.
