A novel (and increasingly imminent) solution to nuclear waste

When Nucleation's portfolio company, Deep Isolation, choose in early 2025 to access the public markets to complete a reverse merger into a shell company and simultaneously raise approximately $30 million—their last tranche of capital—they did so with one big goal in mind: funding the costs to complete their full-scale test of their deep borehole nuclear waste solution.

Deep Isolation had been, by that point, developing this concept and testing aspects of their design for a full decade, having been founded in Berkeley, California in 2016 by the UC Berkeley physicist and MacArthur Genius Award-winner, Prof. Richard Muller, and his daughter, Elizabeth Muller, in an effort to provide a cheaper, easier and yet potentially permanent alternative solution for disposing and/or storing nuclear waste.

The only other waste solutions that have been developed and used for nuclear waste (post-cooling tank) include ground-level storage in dry cask containers in protected areas on the grounds of nuclear power plants (seen as temporary, not completely satisfactory but largely cost-effective), and below-ground mined repositories that are virtually impossible to site (think Yucca Mountain), are quite expensive, difficult and time-consuming to build and which would require being fully staffed and powered forever (needing electrical power for heat, lights, air circulation and ventilation, among other services, and requiring regulators to perform routine checks and security teams to provide protection around the clock, at enormous expense).

In contrast, the Deep Isolation solution leverages highly mature, deep-borehole drilling technology developed for the oil and gas extraction industry (which has now drilled hundreds of thousands of extractions boreholes) but modified so as to enable sealed stainless steel canisters of waste to be lowered into deep, horizontally-drilled boreholes and either termporarily or permanently sealed up, thereby minimizing ongoing costs.

It is an elegant and highly viable solution because the drilling technology exists to emplace those boreholes in layers of the earth's strata a mile or two underground that are highly stable. Deep Isolation has, in the interim ten years, been amassing patents and now has a portfolio of more than 100 patents protecting this waste storage solution. They have been working to educate potential customers about their solution, earning bits of revenue by developing feasibility studies with EPRI for the U.S. and European countries like the UK, Estonia, Solvenia and, through ERDO, Croatia, Denmark, the Netherlands and Norway. And, importantly, they have developed technology and provider partnerships with groups like Halliburton, Bechtel, Amentuk, NAK, Occlusion Nuclear Solutions and Westinghouse. These partners would do the hard work of the drilling, casing and emplacement—which they already know how to do—and Deep Isolation would continue to make sales and earn a premium as the technology developer and owner of the proprietary aspects of their solution. It's a highly workable solution.

Now that Deep Isolation is a publicly listed company (OTCQB: DBHL), there has been growing press coverage of their activities. We expect that, as word gets out, more investors and analysts will come to recognize that Deep Isolation has a very unique opportunity here to help address the nuclear waste issue. Furthermore, assuming their full-scale testing process is successful, there could be a sharp increase in revenues as orders are placed, which for this still small but highly innovative company, means that nearly all of their growth is ahead of them.

Fortune recently published an article by Jordan Blum, titled This nuclear startup and Halliburton repurposed oil-drilling tech in a bid to solve America's radioactive waste problem.  This title may give Halliburton too much credit but, thanks to its successful reverse merger financing, the company has the requisite capital to pay Halliburton to actually drill a new well at the larger diameter specified by the Deep Isolation design and deploy a full-scale test using the universal canister developed with the help of the U.K. government. Proving that they can actually store waste deep underground is the last hurdle anticipated to be covered before quite a few prospective customers could begin to place orders, according to company officials and others.

The Mullers moved on in 2024, having taken the company as far as they could, but Deep Isolation is now led by Rod Baltzer, the CEO since 2024 and the former COO, who is an experienced oil and gas executive. There could well be a little bit of trial and error completing this first true test of the technology, which must be drilled at about triple the standard fracking well size, yet those in the industry with expertise see no major barriers that would prevent their success, and Mr. Baltzer is up for the challenge.  Meanwhile, the real work is now happening at a time of intense and growing interest in deploying additional nuclear power as a solution to energy security, energy growth and concerns about carbon emissions and climate change, and the emergence of an easier, potentially cheaper and more flexible waste storage option can make those deployment decisions easier.

We are thrilled that Deep Isolation is finally going to be able to showcase a true demonstration of their solution and transition from a trickle of revenue—largely from feasibility studies and government grants—to actual orders in the hundreds of millions for their solution to be implemented both in Europe and in the U.S., where progress is being made in solving the nuclear waste storage impasse. The Trump Administration has already made noises about passing legislation that would enable each state to determine if they would like to host a waste storage facility. We think, placing nuclear waste deep underground in safe but cost-effective boreholes could be one of the most important technological steps forward that helps expand support for nuclear power while preserving our ability access to that used fuel material when we have better waste reprocessing capabilities.

Deep Isolation: Now publicly trading and preparing to solve nuclear’s last mile

Nucleation's portfolio company, Deep Isolation, is now a public trading entity, listed on the OTCQB Venture Market as DBHL. We are pleased to have recently announced the registration and listing to our LPs.

Now, the company, led by CEO Rod Baltzer, is focusing its full attention on completing its full-scale demonstration of its technology in Texas. Deep Isolation signed a amaster services agreement with Halliburton, through which Halliburton is providing drilling, well construction and subsurface engineering services for Deep Isolation’s first full-scale demonstration project. Other partners in the project include Westinghouse, NAC International, Occlusion Nuclear Solutions and Amentum.

While few investors are familiar with Deep Isolation Nuclear, as it is now called, Washington Post Intelligence reporter, Kathryn Clay, spoke with Deep Isolation CEO Rod Baltzer about the company’s technology, its recent Department of Energy support, the economics of deep borehole disposal and why he believes advances in drilling technology could reshape the decades-long debate over nuclear waste management. We think you'll find this interview compelling.

Vital Climate Science Resource Re-emerges As Non-Profit

Climate.us launches independent website for trusted climate information

For more than a decade, NOAA’s Climate.gov website was among the U.S. government’s most important platforms for climate information for the public. At the start of 2025, if someone in the U.S. googled “climate,” Climate.gov was the top result. It served 15+ million visitors in 2024 and had more than half a million social media followers and its reach was growing every year.

In the first half of 2025, Trump administration officials at NOAA terminated Climate.gov’s full-time federal and contractor staff, ordered removal of content, and redirected the home page to a page under more direct control of political appointees. With little fanfare, Climate.gov found itself unable to continue its operations which would deprive the public of a highly trusted source of climate information. Finding themselves unable to permit this loss, former Climate.gov staff decided to take matters into their own hands to continue the site's mission. In June, 2026, they launched Climate.us, as a new online platform that will carry on the legacy of Climate.gov and  even expand its scope.

A new home outside the federal domain allows the team to rescue Climate.gov and other federal assets, including the Fifth National Climate Assessment,  bringing key climate information together under one roof. The Climate.gov team, which has long excelled at delivering elegant content through which the public, journalists, educators, and students could easilylearn about climate, will now build a next-generation platform expanded to serve new audiences—climate service providers, community planners, app developers, etc.—seeking data and tools for analysis and decision-making.

Climate.us is now run by an independent nonprofit entity hosted and managed by Multiplier, a 501(c)(3) organization. An advisory panel with members representing target audiences and stakeholders will guide the site’s scope of contents and utility; science and data experts will help content teams ensure information is based on the best available science. We are thrilled by the heroic actions of the Climate.gov staff and their bold, forward-thinking strategy to safeguard public access to vital, trusted climate data and services. We have provided a donation in support of this effort and hope you will too. Please visit the Climate.us fundraising site and consider providing support in any amount.

Nuclear for Climate Change: A luncheon discussion

Luncheon discussion

A Ladies Luncheon discussion of nuclear!

Los Angeles is still reeling from a series of horrific fires that devasted multiple communities, particularly Palisades and Eaton in early 2025. Recent reports found that these fires caused between $28 and $54 billion in property damange, along with what may be $9 billion in related economic losses in LA County alone. The fires have caused a loss of almost 50,000 job-years in the region, reducing area wages, business income, and federal, state and local tax revenue.

Lack of rain, hotter and drier conditions and high winds helped fuel the fires while combating the fires was hindered by the excess heat and widespread shortage of divertable water resources. These are conditions that have been exascerbated by global warming, which is caused by humanity's growing carbon emissions from burning fossil fuels. Gigatonnes of these heat-trapping waste CO2 emissions have amassed within the atmosphere causing the planet to get warmer. Scientists now believe that we've exceeded 1.5°Celsius average increase or 2.7°Fahrenheit and the heating is continuing to rise at an accelerating rate.

While Los Angeles is working to recover, rebuild and repair, the question of how to begin to reverse the damage we're continuing to do to the climate remains. We know with total certainty that we must stop burning fossil fuels. But demand for energy is not just growing around the world, demand is surging—particularly due to AI usage. This means not only do we need to focus on building only new clean energy plants but we also need to replace the 80% of global energy still using fossil fuels with equivalent sources of clean power as well.

We've been building wind and solar as fast as possible but these have never been able to keep up with even the historically lower level of energy growth. Additionally, the enormous costs of "firming" all that dilute and intermittent power (i.e. adding batteries, duplicative generation, and other fossil back up for when the sun and wind aren't cooperating) have increased California ratepayer costs. Meanwhile, we are still reliant on burning fossil fuels for some 60% of our power here in California and new fossil plants continue to get built that lock in continued emissions for decades more, which is extraordinarily bad for our future.

We clearly need better solutions. From our perspective, the only good news on the climate horizon is that energy experts, tech hyperscalers, government officials, industrial companies and investors are increasingly recognizing the importance of nuclear power for addressing our energy and climate needs. Nuclear (fission) power produces massive amounts of energy with zero emissions and runs reliably 24/7 (except for refuelings). It also cleans the air (as it emits zero toxins, unlike coal and gas), it provides good-paying jobs and has one of the smallest possible ecologic footprints. Best of all, there's a race on to develop next-generation nuclear power plants that better meet our 21st century energy needs. (Nuclear fusion may play a role in the future but commercialization of that technology is still much further off.)

Bisconti nuclear surveyNuclear power—and especially newer,  advanced designs—has seen bipartisan support in the Congress since the Obama Administration. Both Biden and Trump have increased funding for development of next-gen nuclear and signed multiples bills to accelerate new deployments for energy security, for climate change and for national security goals. Public support for nuclear power is currently at its highest level in decades. Yet, support by men exceeds that of women overall. Among women, surprisingly, those most concerned about climate change, primarily progressive Democrats, report the least support for nuclear power. This appears to be a function of less awareness and knowledge about the technology and a residual sense that nuclear is dangerous, even though it has been found to be among the safest and cleanest forms of energy ever developed. That does not appear to be common knowledge among women yet.

Valerie Gardner, Nucleation Capital's managing partner, is working to help set the record straight. She is co-hosting a luncheon gathering for an intimate gathering of women in Los Angeles to discuss nuclear power and share what she has learned over the past 15 years of research and investigation, to dispell myths that still infuse women's thinking about nuclear energy.

Official Event Description

Nuclear for Climate

Join a small group of women gathering at an LA restaurant to enjoy a hosted lunch and discussion exploring the proposition that nuclear power could be exactly what we need to meet the surging demand for energy and solve climate climate safely, sustainably and cost-effectively.

As data centers, cloud computing, vehicle electrification, crypto mining, manufacturing and more create unprecedented demand, energy buyers and the broader utility sector in general are facing a pivotal moment. Will we meet this demand with more cheap but often volatile fossil fuel power generation and continue to make our climate crisis worse? Or will we push forward and accelerate the commercialization of revolutionary advanced nuclear technologies that are clean, dense, low-impact, reliable and climate resilient—everything we need! What if next-generation nuclear is able to compete on every level with fossil fuels, including price? This could change our planet's trajectory for the better, reduce emissions, lessen the threat from climate change and help save our children's future.

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?

"The Nuclear Option" panel title displayed on the big screen.      Supply Side

  • 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.
