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.

Net Zero Needs Nuclear


"Rather quietly, a new age of atomic energy may be approaching. Splitting atoms may not be as exciting as fusing them, or as modish as wind and solar projects. Yet old-fashioned fission is poised to make a comeback thanks to innovative new reactor designs. The world will be better for this revolution — if policymakers allow it."

So begins an online article in the Washington Post with the unflinching title "Net Zero Isn't Possible Without Nuclear."  This piece is described as "Analysis by The Editors | Bloomberg."

[Aside: This is an amazing piece of writing—which we entirely agree with and truly admire—but it is all highly unusual. Newspapers typically do not publish "analysis." Also, newspapers typically will not publish opinion pieces from "The Editors" of other organizations. Yet, here it is, Bloomberg Editors (might that include Michael Bloomberg?) have effectively placed an OpEd in the WaPo on the last business day of the year that is, we suspect, going to serve as the exclamation mark for the year. End aside.]

This piece packs a punch. It's not too long. It's not too technical. It just makes the case that we need tons more nuclear energy if we hope to reduce emissions and yet our progress in that direction is blocked by a Nuclear Regulatory Commission that is effectively disfunctional and unable to understand relative risks.

Sadly, we agree. The NRC as it is now, is not well-suited for supporting the success of an innovative nuclear tech sector. Today's NRC could remain the regulator for the traditional industry, which is used to slow and plodding and isn't building all that much. But what the Advanced Nuclear sector needs is a new, more innovative regulatory body which operates at the pace of technology and which can be empowered to use different methods and objectives to provide suitable guidelines and support for innovators but which doesn't stop them from innovating and commercializing good designs, simply because those designs haven't been tested for decades. This group should be empowered to use probabilistic risk assessments, advanced technologies, modeling and even AI to help launch the advanced nuclear sector and ensure that we get the commercial reactor designs we need to prevent climate change from destroying humanity. 

The NRC, as it exists now, does not recognize that climate change is barreling down on the world with an absolute certainty, if we don't eliminate emissions. For the sake of zeroing out risks so miniscule that they don't pose a realistic threat, the NRC is standing in the way of important, planet-saving climate solutions.

Amazon, Ikea and others commit to zero-emission shipping by 2040


An initiative organized by the Aspen Institute helped Amazon, Ikea, Unilever, Michelin and Patagoniz to pledge that they won't use shipping companies which allow emissions by 2040.  Shipping the world's products around produce about 3 percent of human emissions each year, an amount similar to what Germany's annual emissions are, as the sixth largest emitter in the world.

In signing the pledge, the companies hoped to signal their determination to decarbonize this part of their supply chains and inspire "a surge in investment by ocean freight carriers and producers of zero-carbon shipping fuels," their announcement read.  They also urged government officials to "to set ambitious marine fuel goals, implement regulations and market-based measures to encourage the rapid development of new fuels and technology, and to allow zero-carbon shipping fuels to “become competitive with fossil fuels as soon as possible.”

Earth’s health at worst levels on record


Sarah Kaplan's review on the findings released by the National Oceanic & Atmospheric Administration (NOAA) in their report "State of the Climate in 2020," as described in a Washington Post article entitled Many measures of Earth’s health are at worst levels on record, NOAA finds, gives this prognosis: "Earth is arguably in worse shape than it’s been."

Even with a global pandemic that halted commerce and human activities for most of the year, Earth's fever has simply increased and global health metrics—including that for CO2 levels—have just continued to get worse. It's a dire report but nothing new, coming on the heels of the IPCC's "Physical Basis" report and follows along on the same trajectory as eleven prior reports published annually by NOAA.

NOAA’s assessment, published in the Bulletin of the American Meteorological Society, draws on the work of 530 scientists from 66 countries. Atmospheric researchers found no evidence that last year’s 6 to 7% dip in global annual emissions had any lasting effect. The roughly 2 gigatons of carbon dioxide not emitted during the most severe pandemic-related shutdowns have been dwarfed by the more than 1,500 gigatons humans have unleashed since the Industrial Revolution began.

“It’s a record that keeps playing over and over again,” said Jessica Blunden, a NOAA climate scientist who has co-led “State of the Climate” reports for 11 years. “Things are getting more and more intense every year because emissions are happening every year.”.

Because carbon dioxide typically lingers in the atmosphere for a few hundred to 1,000 years, humans will have to stop emitting for much longer than a few months to make a meaningful dent in concentrations of the pollutant. Methane concentrations were also found to have spiked dramatically — rising 14.8 parts per billion to its highest level in millennia. The drilling and distribution of natural gas helps drive up methane emissions. But it is also produced by microbes found in both natural environments such as wetlands and human-built ones such as landfills and farms.

While a spike from natural gas usage is bad, the more worrying possibility is that this increase comes from natural methane sources — such as salt marshes, peatlands and mangrove forests — which would be indicative that we have reached a tipping point, where higher temperatures boost microbe action within thawing permafrost areas. This could continue to add methane for a long time to come, at ever increasing levels, even if we were able to successfully reduce emissions from fossil fuel usage.
