“This is what you’d expect from China,” a veteran mining industry lobbyist told Heatmap.

President Donald Trump is chasing a new American mining boom. In the process, he’s making quick bets on projects that haven’t completed routine financial analyses or would be situated in environmentally sensitive areas with significant legal risk — and occasionally both at the same time.
In March, Trump issued an executive order that changed the landscape of American mining for the foreseeable future, commanding agencies to approve permits for individual mines as quickly as possible and requesting government funds go toward domestic mining. The Interior Department has also taken strides to hasten the environmental review process for mining on federal lands, asserting that it will complete comprehensive analyses in less than 30 days, a truncated time-table the likes of which mining industry lobbyists have long sought.
So far in his second term as president, Trump’s administration has claimed to have approved, expedited, or publicly endorsed at least 28 different mines and mineral exploration projects, according to a review of Bureau of Land Management notices and federal permitting databases, with more likely in the offing. Many of these projects may very well produce minerals required for key energy or defense purposes, and some of them are guaranteed to do so. But at least a few have not yet been proven to be economically viable in the way investors typically expect from mining companies.
Conservationists have decried these actions as an unnecessary risk to sensitive landscapes, which could be irrevocably changed without a guarantee of improved energy security. And even some in the mining industry are quietly noting these examples, saying they could represent a paradigm shift in how America treats the mining industry.
“This is what you’d expect from China,” a former veteran mining industry lobbyist told me, requesting anonymity to protect their current business from retribution. “The U.S. prides itself on mines that are good neighbors. The U.S. doesn’t have a perfect record, but those are things that it values.”
“I’m not saying the companies are going to do something wrong here,” the source continued, “but we don’t know that.”
The most headline-grabbing example of this rush to permit came last week, when the Interior Department said it would fast-track the permitting of a large uranium mine in Utah known as Velvet-Wood. The department said it would complete Velvet-Wood’s environmental review within two weeks — a process that has historically taken years.
On first blush, abbreviating the approval process for a mine that will produce energy fuel for nuclear power plants resembles the sort of permitting reform that climate hawks and centrist policy wonks have craved for years. Velvet-Wood’s developer, Anfield Energy, claims the site will also produce vanadium, a strategic mineral used in defense-grade steel.
A deeper examination, however, exposes signs of haste that go beyond all deliberate speed.
Ordinarily, mines take years to develop for reasons wholly unrelated to the federal permitting process. Usually a project requires years of exploration and study to verify that the area where digging will happen holds proven “resources” and then “reserves.” Think of resources vs. reserves as the difference between lukewarm and high levels of confidence that minerals are not only present but also economic to mine and process. It is unusual for any mine to be built without proven resources, let alone reserves, and feasibility studies are the way companies usually communicate that level of proof to investors. These studies have also been a primary mode of conveying a project’s value and design to the government.
Until our present policy moment, the permitting process was so lengthy that it made little sense to pursue it without first giving investors the certainty brought by a feasibility study. Anfield and other companies appear to have found a work-around to demonstrate that certainty, however, at least to the government: Asking to dig in places where mines used to be decades ago.
Anfield has not yet completed a feasibility study for Velvet-Wood, which would include the site of a former underground uranium mine. The most recent study of the project was a 2023 “preliminary economic assessment” that documented some of the old mining infrastructure and otherwise largely referenced historical data about mineralization. The company stated in the report that the study was “too speculative geologically to have economic considerations applied to them,” and that “there is no certainty that the preliminary economic assessment will be realized.”
In Anfield’s own press release announcing the Trump administration’s decision to quickly permit the project, the company states that it “has not done sufficient work to classify these historic estimates” for uranium and vanadium at the site. Anfield did not respond to requests for comment on why the company requested government permits before finishing a feasibility study.
Under the Velvet-Wood deposit’s previous owner, Russian mining company Uranium One, a draft feasibility study did find economically viable uranium. But that study is more than a decade old and was not made public, according to press materials at the time.
In order to become operational, Anfield expected to have to update the decades-old plan of operations for Velvet-Wood, according to the 2023 economic assessment, which also said BLM would need to take into account the impacts of restarting a formerly operational mine, as well as mining in areas that have not previously been mined before. That’s quite a lot of work to complete in only two weeks. While it’s possible that staff at Interior got a head start on their review when Anfield submitted its mine plan last year, they have not confirmed anything to that effect since the department’s announcement about permitting the project.
Aaron Mintzes, senior policy counsel for the mining reform advocacy group Earthworks, told me the practice of approving a mine before feasibility studies have been done carries the risk of painting a misleading portrait to investors about a project’s viability.
“Every mining company does this. All of them. If you’re a publicly traded mining company and you want investors to give your mine money, you must provide a feasibility study. That’s how you know they’re telling the truth,” Mintzes said of this approach. “Investors should be upset about this.”
In an email, BLM press secretary Brian Hires told me that “feasibility studies are not legally required by BLM for mining projects.”
“The BLM continues to ensure appropriate environmental oversight including coordination with other agencies, balancing mineral development rights and responsible public lands management,” Hires stated.
On Velvet-Wood, Hires said the agency acted under “recently established emergency procedures” created under the Trump administration to quickly approve new resource projects. “The expedited review is expected to significantly contribute to meeting urgent energy demands and addressing key threats to national energy security.”
Velvet-Wood is not the first mine Trump’s Interior Department has expedited so early in the approval process.
On April 8, the Trump administration gave Dateline Resources, an Australian company, a green light to build a large mine inside of the Mojave National Preserve. Like Velvet-Wood, the project, known as Colosseum, got this approval without a feasibility study. Colosseum would be a gold mine, according to Dateline’s website, which also states that the project is “prospective” for producing rare earth elements as a byproduct. The company cites previous radiomagnetic reviews by the U.S. Geological Survey and the project’s proximity of roughly 8 kilometers — or about 6 miles — from an operating rare earths mine, Mountain Pass. The company also cites decades-old information about the site from when it used to be an operating gold mine in the 1970s and 1980s.
Are there rare earths at the Colosseum dig site? There may be — but how much and how commercially useful they’d be are normally determined through a feasibility study process.
BLM approved Colosseum without any new environmental review, or at least nothing that was public at the time it made the decision known. Instead, it said in a five-sentence press statement that Dateline could rely entirely on a construction and operations plan from the previous mine, which shut down in the 1990s.
BLM’s press release also referred to Colosseum as a rare earths mine, with no mention of gold.
“For too long, the United States has depended on foreign adversaries like China for rare earth elements for technologies that are vital to our national security,” the release stated. “By recognizing the mine’s continued right to extract and explore rare earth elements, Interior continues to support industries that boost the nation’s economy and protect national security.”
Hires, the BLM press secretary, told me that the agency made this claim to highlight “the project’s potential to produce rare earth elements, which are required for economic and national security.”
On April 21, investors were informed that a “bankable feasibility study” was now “underway.” But that didn’t stop Trump from jumping far ahead of the usual process a few days later, publicly calling the project “America’s second rare earths mine” on Truth Social.
There’s a big reason this area stopped being mined, by the way: According to the National Park Conservation Association, the area is heavily restricted from mineral development under a law Congress passed in the early 1990s, the California Desert Protection Act.
There is a separate law that provides companies the ability to mine in national preserves and parks under very specific and limited conditions, and with the approval of the National Park Service, the association told me. Kelly Shapiro, an attorney representing Dateline, told E&E News in a story published last week that Interior told the company its mine plan of operations was “valid.” Shapiro also told the news outlet that “rare earths have been found at the Colosseum mine site.”
Dateline has now begun work at the mine site and conservation activists are sounding public alarms. The company did not respond to requests for comment.
Asked why BLM gave Colosseum the right to construct a new operating mine, Hires said the project site, which has not been active for decades, “is not a new mine.” He said the facility was granted the “right” to “continue mining operations” under the plan from when the site was active in the 1980s, which the agency said “includes exploration for rare earth minerals.”
Before I came to Heatmap, I spent years writing about the mining industry. One of the stories I’m proudest of was an investigation into the amount of mining needed to build the vastly different energy and transportation systems we’ll need to fully decarbonize. So I can safely say this: We truly will need more minerals like lithium, copper, nickel, graphite and cobalt to decarbonize, and we might need to open more mines to get them, although recycling and technological innovation could easily reduce the tonnage required over time.
The Trump team has a different argument for mining this much. It says our country needs to wean off foreign sources of metals because relying on imports is a weakness in the eyes of hawkish security experts.
For the past decade, U.S. policymakers of both parties have rallied behind the basic notion that the country should stop relying as much on minerals from nations considered to be adversaries by the national defense apparatus, including China and Russia, as well as companies perceived to be substantially controlled by those nations. The idea first gained traction under Trump 1.0, leading to the creation of a list of so-called “critical minerals” that the military and domestically essential businesses rely on but are generally mined or refined in other countries.
Under Joe Biden, the “critical mineral” concept was magnified by multiple signature laws, including the 2021 infrastructure law and the 2022 Inflation Reduction Act, which together established large grant and tax credit programs intended to stimulate a new American mining economy.
Trump has sped up the federal permitting process for some copper, nickel, and lithium mining and exploration projects. These commodities markets are ones in which China genuinely has an outsized influence, per national security experts, through market share and existing business relationships held by Chinese state-owned mining and refining companies.
Some of these U.S. mining projects likely would’ve been permitted no matter the outcome of last year’s election, either because their environmental impacts would be relatively limited or because they’d produce metals crucial for the energy transition that a Democrat-led government would have supported as a trade-off. Take South32’s Hermosa copper mine in Arizona, which the Biden administration fast-tracked and Trump 2.0 has signaled it will approve. A handful of these mines would supply a meaningful amount of defense minerals for which we currently rely on China, such as the Stibnite gold mine in Idaho, which would yield antimony for military-grade ammo as a byproduct.
Then there are special cases like the Resolution copper mine in Arizona, where the government’s hands are essentially tied under federal legal requirements to approve the conveyance of land to a mining company.
Other “transition metal” mining projects fast-tracked or endorsed by Trump 2.0, however, likely would not have been given priority — or even a second look — under a more neutral federal regulator. That’s because they are located in areas that officials under previous administrations fretted would produce outsized pollution risk and potentially run afoul of environmental laws.
Take for example the NewRange copper mine in Minnesota, which the company says would be the state’s only active copper mine if approved and constructed. NewRange is better known in the mining industry as PolyMet, which was its moniker for most of the nearly two decades it has been in the works. NewRange/PolyMet has struggled to get requisite permits, to the point of being referred to by its opponents as a “zombie” project, because it’s situated in an especially porous area of northern Minnesota covered in protected wetlands.
In 2022, the Environmental Protection Agency under Biden said the Army Corps of Engineers should rescind a water permit issued under Trump 1.0 because the project would violate the pollution standards of the Fond du Lac Tribe, which relies on the wet ecosystem to cultivate wild rice for subsistence and cultural practices.
At the beginning of May, the Trump administration added NewRange/PolyMet to a federal “transparency” dashboard that it says will soon have a timetable for approving the project under the same authority it fast-tracked Resolution. Representative Pete Stauber of Minnesota, whose congressional district includes the mining project, reacted in a statement that said the designation shows Trump “understands the vital importance of this project,” and that he looks forward to “seeing NewRange meet and exceed every permitting standard in a timely manner.”
This is an example of mine that, if approved hastily, would probably create new litigation just as fast.
At the risk of repeating myself, it’s not the only example of such a case, and there are more examples where the Trump administration has opened the door to new, legally risky directions on a mine.
Most notable in that pile is the Pebble mine in Alaska, which Trump halted during his first term but may be given what appears to be a last shot at survival under his new government. Decades of battle between a would-be gold mine and the denizens of Bristol Bay have dominated conversations around American mining. Opponents across the political spectrum have tried to stop the project because they fear construction would pollute the bay and its world-class fishing grounds.
The first Trump administration actually opposed Pebble after a private lobbying campaign by Donald Trump, Jr. and other conservative conservation advocates. Under Biden, the EPA issued a rare veto of the project area under a provision of the Clean Water Act. This was a step beyond simply rejecting the permit as it would, in the view of advocates, be a permanent restriction against development.
In February, the Trump 2.0 Justice Department requested a stay on the federal lawsuit filed against the veto by Pebble’s developer, Northern Dynasty Minerals, alongside top political leaders in the state of Alaska, who have argued that the agency overstepped its authority. On Wednesday, Justice Department attorneys filed a status report asking that the stay be extended for at least another month because while officials had been briefed on the subject, they “require additional time to determine how they wish to proceed.”
This indicates the government is still not ready to state its position, and leaves open a door for the Justice Department to flip sides. Northern Dynasty Minerals hopes a flip will happen. “This is an important position in any negotiation between a project proponent and a regulator, and for a process that could, hopefully, remove the veto and re-start the permitting process,” the company’s CEO Ron Thiessen said in a public statement made after the stay extension request.
It may be that even Pebble Mine is a bridge too far for Trump 2.0. But after all these other projects have gotten the skids greased, we must all wait with bated breath for the next shoe — er, pebble — to drop.

The administration has already lost once in court wielding the same argument against Revolution Wind.
The Trump administration says it has halted all construction on offshore wind projects, citing “national security concerns.”
Interior Secretary Doug Burgum announced the move Monday morning on X: “Due to national security concerns identified by @DeptofWar, @Interior is PAUSING leases for 5 expensive, unreliable, heavily subsidized offshore wind farms!”
There are only five offshore wind projects currently under construction in U.S. waters: Vineyard Wind, Revolution Wind, Coastal Virginia Offshore Wind, Sunrise Wind, and Empire Wind. Burgum confirmed to Fox Business that these were the five projects whose leases have been targeted for termination, and that notices were being sent to the project developers today to halt work.
“The Department of War has come back conclusively that the issues related to these large offshore wind programs create radar interference, create genuine risk for the U.S., particularly related to where they are in proximity to our East Coast population centers,” Burgum told the network’s Maria Bartiromo.
David Schoetz, a spokesperson for Empire Wind's developer Equinor, told me the company is “aware of the stop work order announced by the Department of Interior,” and that the company is “evaluating the order and seeking further information from the federal government.” Schoetz added that we should ”expect more to come” from the company.
This action takes a kernel of truth — that offshore wind can cause interference with radar communication — and blows it up well beyond its apparent implications. Interior has cited reports from the military they claim are classified, so we can’t say what fresh findings forced defense officials to undermine many years of work to ensure that offshore wind development does not impede security or the readiness of U.S. armed forces.
The Trump administration has already lost once in court with a national security argument, when it tried to halt work on Revolution Wind citing these same concerns. The government’s case fell apart after project developer Orsted presented clear evidence that the government had already considered radar issues and found no reason to oppose the project. The timing here is also eyebrow-raising, as the Army Corps of Engineers — a subagency within the military — approved continued construction on Vineyard Wind just three days ago.
It’s also important to remember where this anti-offshore wind strategy came from. In January, I broke news that a coalition of activists fighting against offshore wind had submitted a blueprint to Trump officials laying out potential ways to stop projects, including those already under construction. Among these was a plan to cancel leases by citing national security concerns.
In a press release, the American Clean Power Association took the Trump administration to task for “taking more electricity off the grid while telling thousands of American workers to leave the job site.”
“The Trump Administration’s decision to stop construction of five major energy projects demonstrates that they either don’t understand the affordability crises facing millions of Americans or simply don't care,” the group said. “On the first day of this Administration, the President announced an energy emergency. Over the last year, they worked to create one with electricity prices rising faster under President Trump than any President in recent history."
What comes next will be legal, political and highly dramatic. In the immediate term, it’s likely that after the previous Revolution victory, companies will take the Trump administration to court seeking preliminary injunctions as soon as complaints can be drawn up. Democrats in Congress are almost certainly going to take this action into permitting reform talks, too, after squabbling over offshore wind nearly derailed a House bill revising the National Environmental Policy Act last week.
Heatmap has reached out to all of the offshore wind developers affected, and we’ll update this story if and when we hear back from them.
Editor’s note: This story has been updated to reflect comment from Equinor and ACP.
On Redwood Materials’ milestone, states welcome geothermal, and Indian nuclear
Current conditions: Powerful winds of up to 50 miles per hour are putting the Front Range states from Wyoming to Colorado at high risk of wildfire • Temperatures are set to feel like 101 degrees Fahrenheit in Santa Fe in northern Argentina • Benin is bracing for flood flooding as thunderstorms deluge the West African nation.

New York Governor Kathy Hochul inked a partnership agreement with Ontario Premier Doug Ford on Friday to work together on establishing supply chains and best practices for deploying next-generation nuclear technology. Unlike many other states whose formal pronouncements about nuclear power are limited to as-yet-unbuilt small modular reactors, the document promised to establish “a framework for collaboration on the development of advanced nuclear technologies, including large-scale nuclear” and SMRs. Ontario’s government-owned utility just broke ground on what could be the continent’s first SMR, a 300-megawatt reactor with a traditional, water-cooled design at the Darlington nuclear plant. New York, meanwhile, has vowed to build at least 1 gigawatt of new nuclear power in the state through its government-owned New York Power Authority. Heatmap’s Matthew Zeitlin wrote about the similarities between the two state-controlled utilities back when New York announced its plans. “This first-of-its-kind agreement represents a bold step forward in our relationship and New York’s pursuit of a clean energy future,” Hochul said in a press release. “By partnering with Ontario Power Generation and its extensive nuclear experience, New York is positioning itself at the forefront of advanced nuclear technology deployment, ensuring we have safe, reliable, affordable, and carbon-free energy that will help power the jobs of tomorrow.”
Hochul is on something of a roll. She also repealed a rule that’s been on the books for nearly 140 years that provided free hookups to the gas system for new customers in the state. The so-called 100-foot-rule is a reference to how much pipe the state would subsidize. The out-of-pocket cost for builders to link to the local gas network will likely be thousands of dollars, putting the alternative of using electric heat and cooking appliances on a level playing field. “It’s simply unfair, especially when so many people are struggling right now, to expect existing utility ratepayers to foot the bill for a gas hookup at a brand new house that is not their own,” Hochul said in a statement. “I have made affordability a top priority and doing away with this 40-year-old subsidy that has outlived its purpose will help with that.”
Redwood Materials, the battery recycling startup led by Tesla cofounder J.B. Straubel, has entered into commercial production at its South Carolina facility. The first phase of the $3.5 billion plant “has brought a system online that’s capable of recovering 20,000 metric tons of critical minerals annually, which isn’t full capacity,” Sawyer Merritt, a Tesla investor, posted on X. “Redwood’s goal is to keep these resources here; recovered, refined, and redeployed for America’s advantage,” the company wrote in a blog post on its website. “This strategy turns yesterday’s imports into tomorrow’s strategic stockpile, making the U.S. stronger, more competitive, and less vulnerable to supply chains controlled by China and other foreign adversaries.”
A 13-state alliance at the National Association of State Energy Officials launched a new accelerator program Friday that’s meant to “rapidly expand geothermal power development.” The effort, led by state energy offices in Arizona, California, Colorado, Hawaii, Idaho, Louisiana, Montana, Nevada, New Mexico, Oregon, Pennsylvania, Utah, and West Virginia, “will work to establish statewide geothermal power goals and to advance policies and programs that reduce project costs, address regulatory barriers, and speed the deployment of reliable, firm, flexible power to the grid.” Statements from governors of red and blue states highlighted the energy source’s bipartisan appeal. California Governor Gavin Newsom, a Democrat, called geothermal a key tool to “confront the climate crisis.” Idaho’s GOP Governor Brad Little, meanwhile, said geothermal power “strengthens communities, supports economic growth, and keeps our grid resilient.” If you want to review why geothermal is making a comeback, read this piece by Matthew.

Yet another pipeline is getting the greenlight. Last week, the Federal Energy Regulatory Commission approved plans for Mountain Valley’s Southgate pipeline, clearing the way for construction. The move to shorten the pipeline’s length from 75 miles down to 31 miles, while increasing the diameter of the project to 30 inches from between 16 and 23 inches, hinged on whether FERC deemed the gas conduit necessary. On Thursday, E&E News reported, FERC said the developers had demonstrated a need for the pipeline stretching from the existing Mountain Valley pipeline into North Carolina.
Last week, I told you about a bill proposed in India’s parliament to reform the country’s civil liability law and open the nuclear industry to foreign companies. In the 2010s, India passed a law designed to avoid another disaster like the 1984 Bhopal chemical leak that killed thousands but largely gave the subsidiary of the Dow Chemical Corporation that was responsible for the accident a pass on payouts to victims. As a result, virtually no foreign nuclear companies wanted to operate in India, lest an accident result in astronomical legal expenses in the country. (The one exception was Russia’s state-owned Rosatom.) In a bid to attract Western reactor companies, Indian lawmakers in both houses of parliament voted to repeal the liability provisions, NucNet reported.
The critically endangered Lesser Antillean iguana has made a stunning recovery on the tiny, uninhabited islet of Prickly Pear East near Anguilla. A population of roughly 10 breeding-aged lizards ballooned to 500 in the past five years. “Prickly Pear East has become a beacon of hope for these gorgeous lizards — and proves that when we give native wildlife the chance, they know what to do,” Jenny Daltry, Caribbean Alliance Director of nature charities Fauna & Flora and Re:wild, told Euronews.
The fourth-generation gas-cooled reactor company ZettaJoule is setting up shop at an unnamed university.
The appeal of next-generation nuclear technology is simple. Unlike the vast majority of existing reactors that use water, so-called fourth-generation units use coolants such as molten salt, liquid metal, or gases that can withstand intense heat such as helium. That allows the machines to reach and maintain the high temperatures necessary to decarbonize industrial processes, which currently only fossil fuels are able to reach.
But the execution requirements of these advanced reactors are complex, making skepticism easy to understand. While the U.S., Germany, and other countries experimented with fourth-generation reactors in earlier decades, there is only one commercial unit in operation today. That’s in China, arguably the leader in advanced nuclear, which hooked up a demonstration model of a high-temperature gas-cooled reactor to its grid two years ago, and just approved building another project in September.
Then there’s Japan, which has been operating its own high-temperature gas-cooled reactor for 27 years at a government research site in Ibaraki Prefecture, about 90 minutes north of Tokyo by train. Unlike China’s design, it’s not a commercial power reactor. Also unlike China’s design, it’s coming to America.
Heatmap has learned that ZettaJoule, an American-Japanese startup led by engineers who worked on that reactor, is now coming out of stealth and laying plans to build its first plant in Texas.
For months, the company has quietly staffed up its team of American and Japanese executives, including a former U.S. Nuclear Regulatory Commission official and a high-ranking ex-administrator from the industrial giant Mitsubishi. It’s now preparing to decamp from its initial home base in Rockville, Maryland, to the Lone Star State as it prepares to announce its debut project at an as-yet-unnamed university in Texas.
“We haven’t built a nuclear reactor in many, many decades, so you have only a handful of people who experienced the full cycle from design to operations,” Mitsuo Shimofuji, ZettaJoule’s chief executive, told me. “We need to complete this before they retire.”
That’s where the company sees its advantage over rivals in the race to build the West’s first commercial high-temperature gas reactor, such as Amazon-backed X-energy or Canada’s StarCore nuclear. ZettaJoule’s chief nuclear office, Kazuhiko Kunitomi, oversaw the construction of Japan’s research reactor in the 1990s. He’s considered Japan’s leading expert in high-temperature gas reactors.
“Our chief nuclear officer and some of our engineers are the only people in the Western world who have experience of the whole cycle from design to construction to operation of a high temperature gas reactor,” Shimofuji said.
Like X-energy’s reactor, ZettaJoule’s design is a small modular reactor. With a capacity of 30 megawatts of thermal output and 12 megawatts of electricity, the ZettaJoule reactor qualifies as a microreactor, a subcategory of SMR that includes anything 20 megawatts of electricity or less. Both companies’ reactors will also run on TRISO, a special kind of enriched uranium with cladding on each pellet that makes the fuel safer and more efficient at higher temperatures.
While X-energy’s debut project that Amazon is financing in Washington State is a nearly 1-gigawatt power station made up of at least a dozen of the American startup’s 80-megawatt reactors, ZettaJoule isn’t looking to generate electricity.
The first new reactor in Texas will be a research reactor, but the company’s focus is on producing heat. The reactor already working in Japan, which produces heat, demonstrates that the design can reach 950 degrees Celsius, roughly 25% higher than the operating temperature of China’s reactor.
The potential for use in industrial applications has begun to attract corporate partners. In a letter sent Monday to Ted Garrish, the U.S. assistant secretary of energy in charge of nuclear power — a copy of which I obtained — the U.S. subsidiary of the Saudi Arabian oil goliath Aramco urged the Trump administration to support ZettaJoule, and said that it would “consider their application to our operations” as the technology matures. ZettaJoule is in talks with at least two other multinational corporations.
The first new reactor ZettaJoule builds won’t be identical to the unit in Japan, Shimofuji said.
“We are going to modernize this reactor together with the Japanese and U.S. engineering partners,” he said. “The research reactor is robust and solid, but it’s over-engineered. What we want to do is use the safety basis but to make it more economic and competitive.”
Once ZettaJoule proves its ability to build and operate a new unit in Texas, the company will start exporting the technology back to Japan. The microreactor will be its first product line.
“But in the future, we can scale up to 20 times bigger,” Shimofuji said. “We can do 600 megawatts thermal and 300 megawatts electric.”
Another benefit ZettaJoule can tap into is the sweeping deal President Donald Trump brokered with Japanese Prime Minister Sanae Takaichi in October, which included hundreds of billions of dollars for new reactors of varying sizes, including the large-scale Westinghouse AP1000. That included financing to build GE Vernova Hitachi Nuclear Energy’s 300-megawatt BWRX-300, one of the West’s leading third-generation SMRs, which uses a traditional water-cooled design.
Unlike that unit, however, ZettaJoule’s micro-reactor is not a first-of-a-kind technology, said Chris Gadomski, the lead nuclear analyst at the consultancy BloombergNEF.
“It’s operated in Japan for a long, long time,” he told me. “So that second-of-a-kind is an attractive feature. Some of these companies have never operated a reactor. This one has done that.”
A similar dynamic almost played out with large-scale reactors more than two decades ago. In the late 1990s, Japanese developers built four of GE and Hitachi’s ABWR reactor, a large-scale unit with some of the key safety features that make the AP1000 stand out compared to its first- and second-generation predecessors. In the mid 2000s, the U.S. certified the design and planned to build a pair in South Texas. But the project never materialized, and America instead put its resources into Westinghouse’s design.
But the market is different today. Electricity demand is surging in the near term from data centers and in the long term from electrification of cars and industry. The need to curb fossil fuel consumption in the face of worsening climate change is more widely accepted than ever. And China’s growing dominance over nuclear energy has rattled officials from Tokyo to Washington.
“We need to deploy this as soon as possible to not lose the experienced people in Japan and the U.S.,” Shimofuji said. “In two or three years time, we will get a construction permit ideally. We are targeting the early 2030s.”
If every company publicly holding itself to that timeline is successful, the nuclear industry will be a crowded field. But as history shows, those with the experience to actually take a reactor from paper to concrete may have an advantage.
