For the first time in six years, House Democrats have put forward a climate platform.
Well, sort of. On Tuesday, a subset of nine House Democrats who are part of the Sustainable Energy and Environment Coalition published a menu of hundreds of policy proposals called the Thriving Economy Project. It’s a federal blueprint for the age of AI, surging energy demand, worsening natural disasters, and growing geopolitical uncertainty.
Kathy Castor, a representative from Florida who led the project, told me that instead of a platform, I should think of the project as “a workable plan for long term economic and job growth.”
“We’re not introducing a bill after this,” she said. “We’re providing it to policymakers in Washington for them to build the bipartisan support you need to get something across the finish line. The Trump administration is going to be there for two more years. What can we get done now that would have bipartisan support?”
Nevertheless, this is still the most sweeping environment and energy policy document Democrats have published since 2020, when the House Select Committee on the Climate Crisis — which Castor also chaired — published a nearly 550-page plan to “solve the climate crisis.” Much of that work became a part of the 2021 bipartisan infrastructure law and the 2022 Inflation Reduction Act. Of course, significant chunks of those laws, including tax credits for wind and solar projects, were later dismantled by the Trump administration in the One Big Beautiful Bill Act.
The Climate Crisis Committee disbanded in 2023, but the Thriving Economy Project is, in some ways, a continuation of its work. The document itself is the product of an independent nonprofit, which Democrats from the Sustainable Energy and Environment Coalition enlisted to probe experts, local leaders, companies, and advocates around the country for ideas about what Congress should do to create jobs, lower energy costs, foster innovation, and shore up communities. The nonprofit, known as the Sustainable Energy and Environment Coalition Institute, convened working groups, roundtables, and listening sessions. It also issued a public Request for Information that generated more than 1,300 policy recommendations from around 150 responders, including businesses and trade associations, local governments, nonprofits, and universities, the report said, and assembled a “20-person steering committee of ideologically diverse experts” to challenge its own assumptions.
The resulting report asserts that it is “not a consensus document, nor was it ever intended to be. It is a menu of ideas that have been challenged, refined, and improved by people approaching the same problems from very different perspectives.”
Perhaps that’s why the document reads a little bit like throwing spaghetti at the wall. There’s plenty in it that could conceivably be bipartisan, but there’s also a lot that stands no chance of passing under Trump, even if Democrats take the House and Senate in November’s midterm elections. In that light, it’s both a menu for the next two years and a window into how Democrats are generally thinking about climate policy in the post-IRA era. Here are five of my takeaways after going through it.
The authors do not spill any digital ink lamenting Trump’s dismantling of the IRA. They do, however, propose restoring a bunch of what’s been lost and building on the lessons learned from the brief time the policies were in effect.
For example, the report suggests reinstating federal tax credits for home energy efficiency improvements and residential clean energy systems such as rooftop solar, but recommends offering the credits as a point-of-sale rebate rather than a return claimed on the buyer’s taxes. That would be similar to the way electric vehicle buyers could transfer their tax credit to the dealer to get the discount on their purchase immediately. The goal, according to the report, is to “minimize the upfront costs and administrative frictions for consumer-facing incentives.”
Speaking of the electric vehicle tax credit, bringing it back is also on the menu, justified as a demand pull to support domestic supply chains and as a complement to the manufacturing tax credits, which largely survived the IRA purge (more on that below). Interestingly, a separate section of the report proposes a perhaps more politically palatable consumer rebate for new vehicles based on fuel efficiency rather than a strict EV-only subsidy, framing the idea as an option to address “unaffordable gasoline.”
There is a meaty section on extending and expanding the manufacturing tax credits, which, as you may remember, will no longer apply to wind turbine components after 2027, thanks to Trump’s One Big Beautiful Bill Act. The report suggests cancelling that early termination. It also proposes extending the subsidy to a long list of additional advanced energy technologies, including power transformers, industrial heat pumps, and long duration energy storage components. Additionally, there are several sections on improving federal support for early-stage technologies, helping them get through the “valley of death” to commercial deployment — a major theme in both the bipartisan infrastructure law and IRA.
Notably absent is any discussion of reinstating the tax credits for wind and solar generation. When I asked Castor about that, she said “a lot of that ground had been plowed already,” referring to the contentious battle over the credits during the OBBBA negotiations. “In this Congress, that’s not going to happen. This effort is driven by solving problems ASAP where we think there can be bipartisan support going forward.”
The report intentionally stays away from one of the most significant ways Congress could speed up solutions to address rising energy demand: permitting reform. A disclaimer at the top notes that since Congress was actively debating legislation on that issue while the report was being written, the authors chose not to tackle it directly.
It does, however, spend plenty of time working around the edges on ways to clear up clogged interconnection queues and fix bottlenecks to getting more transmission online. For one, it suggests more funding for the Department of Energy’s Transmission Facilitation Program, which allows the agency to temporarily serve as an anchor customer for new transmission lines. Creating a 30% investment tax credit for transmission lines is another idea in the report.
A lot of the recommendations revolve around improving grid planning and integrating grid-enhancing technologies, advanced conductors, and energy storage into the process. The report suggests establishing a national transmission conductor standard, for example, setting a minimum efficiency level for the wires strung along transmission lines to reduce waste.
Beyond transmission, there are a slew of ideas for reforming energy markets to better support demand response and virtual power plants. Congress could create federal guidance for how grid operators and state regulators assess the value of energy storage to the grid, and direct the DOE to provide more technical assistance to operators on incorporating flexible resources that can shift load, relieve congestion, and integrate more renewables into the grid.
One of the biggest challenges Democrats will have to contend with is writing policy that can endure past a change in party control. Trump has found myriad ways to block projects approved by the previous administration and withhold congressionally mandated funding. The courts are still deciding whether his administration’s methods are actually legal. Nonetheless, the report reflects an interest in creating more certainty for federal grantees and restoring trust in the federal government as a funding partner.
For one, it explicitly recommends that Congress restore awards that were legally obligated under IRA programs such as the Greenhouse Gas Reduction Fund, the Environmental and Climate Justice Block Grants, the Community Change Grants, and the Neighborhood Access and Equity Grants that the Trump administration has attempted to terminate — though it stops short of specifying how.
In the future, though, it recommends that federal funding be funneled through “trusted third-party fiscal intermediaries to allow for nimbler program management and structural insulation from political shifts.” Congress should also more narrowly define the circumstances under which an award can be terminated, it says, offering the suggested language: “funds awarded under [identified programs] may not be rescinded, reprogrammed, or deferred except by law.”
In cases where an administration does rescind or terminate funding, it recommends that Congress put in law that any legal challenge to the termination belongs in the U.S. District Courts. The Department of Justice is attempting to argue that the disputes over Trump’s grant terminations constitute breach of contract claims, and therefore belong in the court of federal claims. If the cases end up there, however, the grantees will only be able to sue for damages — they won’t be eligible to get their grants reinstated. A provision explicitly placing these cases in the district court would ensure awardees have a path to actually contributing to congressionally-mandated goals.
While these provisions are promising, however, it’s hard to imagine that Trump would sign off on them.
One of the most obvious differences between the world we live in now and the world lawmakers occupied in 2020 is that the race for artificial intelligence is in full swing, driving a surge in electricity demand the country has not seen in decades. Data centers have become the locus of a number of intersecting issues — permitting obstacles for energy infrastructure, rising electricity costs, local opposition to anything getting built at all, fear of AI, and concerns about cybersecurity.
The Thriving Economy Project treats data centers as a central organizing problem across several of its chapters. It offers policies to address environmental concerns such as requiring data centers to use closed-loop cooling systems to reduce water use. It proposes unifying the piecemeal approach states are taking to meet data center electricity demand under a federal standard that would require large loads to pay the full cost of connecting to the grid.
There’s a whole section on the challenges of meeting data centers’ power needs that contains more than two dozen policy ideas. A few that stand out include mandatory energy and water use disclosure requirements, a federal Energy Star-equivalent for AI tools, and the creation of a “U.S. Electron Accelerator.” That last idea is one of the most interesting proposals I came across. Data centers would pay into a fund for every kilowatt-hour of their demand not met with clean electrons generated at the same time and in the same location. The funds would then be available to help data centers cover the premium for procuring round-the-clock clean electricity, such as nuclear and geothermal power.
Similarly, the report suggests requiring data centers to pay into a fund to support the Low Income Home Energy Assistance Program and the Weatherization Assistance Program, two perennially underfunded federal programs that help Americans who are struggling to pay their energy bills.
It also raises the concern that data centers powered by behind-the-meter natural gas plants will drive up the price of natural gas for other customers, thereby increasing home heating and residential electricity bills. The report suggests several ideas to reduce natural gas price volatility, including taxing oil and gas companies to create a “strategic energy affordability reserve.” If the president declares an “energy affordability emergency,” it says, the funds can be released to states to help residents pay their bills. Additionally, Congress could create an “energy price safety valve” to temporarily ban exports of key fuels when prices spike.
A lot of the Thriving Economy Project reads like a manual for playing defense in an increasingly dangerous world. It is consumed with addressing risk — the risk of cybersecurity attacks on our electric grid, water systems, and airports, and of global supply shocks that throttle domestic energy prices and supply chains. While discussion of “climate change” as a problem to tackle is notably absent from the report, a rhetorical shift I wrote more about here, adapting to the realities of a warming planet is one of its main preoccupations.
It suggests establishing a federal climate relocation program, for example, and setting federal climate-adapted transportation standards, such as elevation in flood zones and transit facility shading. There’s a recommendation to build a “national climate-health early warning system” to alert people about extreme heat, wildfire smoke, vector-borne diseases, and harmful algal blooms. Along those lines, it suggests that severe wildfire smoke events qualify for federal disaster assistance. At the same time, federal disaster assistance is too fragmented across various agencies, it says, and the government could establish a single, mobile-friendly app “as the front door to all federal individual disaster aid.”
It recommends creating an independent National Disaster Safety Board, an independent watchdog to investigate deaths and damages after a disaster and issue recommendations for how governments at all levels can prevent these losses the next time. Congress could also establish a national climate risk disclosure standard for the real estate industry, giving homebuyers access to more consistent, transparent data about property risks.
These are just a few of many dozens of proposals to improve federal leadership on this especially local, disjointed issue.

Smoke from the raging fires in Indonesia may go down as this year’s deadliest climate tragedy.
It’s a morbid game to try to name the worst climate disaster of 2026. In Europe this summer, a series of extreme heat waves killed an estimated 50,000 people. In September, a thawing Himalayan glacier collapsed, sending a wall of water cascading through Tibet and Nepal, killing at least 1,500 people, with nearly 6,000 still missing months later. And this past January, authorities feared hundreds of migrants died while trying to cross the Mediterranean during Cyclone Harry, including 50 in one shipwreck alone.
But the disaster that will result in perhaps the greatest and longest-lasting tragedy is the one unfolding right now in Indonesia.
Wildfires in Sumatra and Kalimantan have burned more than 7 million acres in what is likely a record year for the fire-prone islands. The blazes have destroyed critical wildlife habitats, including rainforests occupied by orangutans, Sunda pangolins, and Javan leopards. But it’s not the direct human deaths from the fires, the habitat loss, or the historic acreage burned — those being the typical headline numbers for gauging how “bad” a given fire or fire season is — that best tell the story of the impacts, in this case.
Rather, it is the toxic smoke blanketing Indonesia, Singapore, Malaysia, and Timor-Leste. For months, those emissions have been in every breath taken by the region’s 12.5 million inhabitants, about 4% of the world’s population.
In Indonesia alone, authorities estimate the smoke has caused 400,000 respiratory infections. As of a few weeks ago, more than 75,000 cases had been recorded in children between birth and age 5. “Behind those numbers are worried families, parents keeping watch, and children struggling to breathe,” Herawati Supolo-Sudoyo, a trustee of the Indonesian Open Science Voice Foundation and chair of the Indonesian Academy of Sciences’ Commission on Medical Sciences, said during a recent public health webinar. “Babies certainly cannot say, ‘My chest feels tight.’ They rely on us to protect their breath.” (That’s according to an automated YouTube translation of her remarks.)

Children are especially vulnerable to wildfire smoke because their lungs are not fully developed, and they breathe in more air relative to their body weight than adults. Reports from local hospitals are harrowing. “Yesterday, in the inpatient ward, I saw three toddlers struggling to breathe,” one mother, whose 14-month-old died suddenly after experiencing shortness of breath, told BBC Indonesia (as translated by Mongabay). The Indonesian Philanthropy Association, a nonprofit, has taken to describing the children of Indonesia as the “lost generation” due to the suspected physical and cognitive toll of the relentless smoke exposure. Timor-Leste, which borders Indonesia to the west, has one of Asia’s youngest populations, with about 44% of its inhabitants under 18.
“We must not wait until these children are adults to calculate the losses,” Supolo-Sudoyo said.
There seems little doubt that the smoke is a climate-change-fueled public health crisis. A new study by World Weather Attribution, released Thursday, found that while the super El Niño is the primary cause of the severe reduction in rainfall that helped fuel the fires, Indonesia’s drought was “then exacerbated by record heat throughout the fire season, which was made possible due to human-caused climate change,” Theodore Keeping, a research associate with WWA, said during a press call about the findings. (The study, which uses peer-reviewed methods, has not yet been peer-reviewed itself.)
Indonesia’s fire season was about 1.6 degrees Celsius hotter due to climate change, compared to about a third of a degree Celsius hotter due to the current El Niño, WWA reports. “We also found that this year’s record-breaking heat would have been virtually impossible without climate change, even in a similar El Niño state,” Keeping said.

Smoke is still a relatively new way of quantifying the impact of a wildfire. Alistair Hayden, an assistant professor of practice in Cornell’s Department of Public and Ecosystem Health and creator of the school’s wildfire smoke mortality estimation tool, told me that though researchers have been studying smoke toxicity for years, the bad U.S. fire seasons in 2018 and 2020 helped accelerate interest and urgency. “Really high visibility and growing interest leads to a lot more studies that then enhance our knowledge about the details of this hazard,” he said of the recent spike in smoke-related research.
For example, new research released just last month by researchers at Harvard indicates that wildfire smoke exposure during pregnancy is related to higher instances of autism in children. Separately, a study about chronic wildfire smoke exposure linked the pollution to an estimated 24,100 deaths in the lower 48 states every year — more than twice the number killed in drunk-driving accidents. Looking only at Indonesia, researchers linked smoke exposure in the womb during the region’s severe 1997 fire season to poorer health outcomes by age 17.
Still, coverage of wildfires largely focuses on how many people were killed by direct flame impacts, or how many acres or buildings burned. A “megafire,” for example, is a nonscientific term used by the media to describe how large a fire is physically, but not the thousands of miles further its smoke will travel. The National Interagency Coordination Center’s Wildland Fire Summary and Statistics Annual Report, the end-of-year summary of fire season impacts in the United States, doesn’t even mention smoke exposure. Deadly and destructive fires in Maui and Los Angeles stand out in memory, but the hazardous air quality in the Midwest this season from the Canadian wildfires may turn out to cost as many or more lives. (Smoke toxicity and chronic exposure also complicate the cost-benefit analysis of a favorite tool of progressive fire managers: prescribed burns.)
In fact, research about smoke toxicity and widespread exposure to particulate pollution increasingly suggests that emissions might be the marquee impact of wildfires. While 30 people died directly from the 2025 Palisades and Eaton fires in L.A., one research paper estimated the loss of life was closer to 440, partially due to the deaths attributable to wildfire smoke in addition to stress, disruptions to the health-care infrastructure, and mental health impacts.

“The difficulty with all of this is that the smoke deaths are difficult to track,” Hayden told me. “They’re not, for instance, showing up on death certificates. While the smoke itself is very visible in the air and leads to nice photos, the impacts are much harder to take photos of.”
That’s certainly the case in Indonesia, where photos show people going about their lives in a cloud of yellow smoke, and in Singapore, where run clubs have moved their workouts into malls to try to avoid the pollution. But while a smoke-exacerbated heart attack isn’t a front-page image, to Hayden’s point, the pictures do reveal something else: just how ill-prepared our infrastructure and public health systems are for dramatic smoke events like these.
What can be done about wildfire smoke? You can invest in a really good air purifier — and use it correctly — which works so long as you can afford it, and if your home isn’t drafty to begin with, and if it isn’t too hot out that you need to open a window to stay cool at the same time. You can wear the right kind of mask, too, but it needs to fit properly and it won’t filter out gases or the smallest toxic particles. And while you can evacuate to protect yourself from an encroaching wildfire, outrunning the smoke might require you to travel hundreds of miles or, as is the case for those in Southeast Asia, literally leave your country.
In that sense, we are thinking about wildfire impacts wrong, too. Fires aren’t a hazard contained neatly within evacuation zones; the “wildland-urban interface” and “wildfire-prone landscape” describe an environment fires may erupt in, but not what they’re contained to. Whether you’re in Los Angeles or New York City, Minneapolis or Madrid, Jakarta or Kuala Lumpur, the smoke will find you.
We need a ratepayer protection pledge for natural gas, too, argue two energy systems experts.
Everyone is talking about high energy prices, which were a major factor in the midterm elections. And it’s not just electricity: Families are paying 16% more for natural gas now than they were just two years ago. Within a few more years, the boom in electricity demand from data centers could add enough natural gas power plants to expand America’s gas power generation capacity by a third. Some back of the envelope math shows that the additional costs to regular customers from this expansion could total more than $23 billion across all retail gas and electricity prices by 2030.
Large users choosing gas will raise costs for the more than 70 million households in America paying a gas bill every month. It’s simple supply and demand. Some data center developers are working with utilities to connect to the grid, but many others are building their own off-grid power plants that would burn natural gas to power their operations. That would require a massive gas infrastructure build-out on top of the supply pressure, raising costs still further.
Earlier this year, hyperscalers and AI companies signed the Ratepayer Protection Pledge, committing to pay the full costs of their energy and infrastructure, “no matter what,” to avoid increasing energy costs for other customers. Agreeing to limit cost increases for energy is a good start, but the details of that pledge focused only on electricity customers, and it’s not enough to solve the problem. Almost nothing has been said on what that means for natural gas customers, or how data centers should help contain gas costs for families. As the 120th Congress, newly elected governors, and state legislators across the country consider the fastest ways to tackle volatile energy prices, they should consider a Gas Customer Protection Pledge to protect consumers from data centers contributing to surging natural gas bills.
All this new gas demand from data centers could increase costs for the rest of us in at least three ways. First, if history is any indication, the sheer volume of increased gas use will both raise gas prices and make them more volatile. Price volatility hurts poorer consumers more, with surprisingly high bills derived from market dynamics over which they have little control. Second, the pipelines, compressor stations, and other infrastructure needed to bring gas to these new facilities will cost money. Because the vast majority of utilities in America pass through both the cost of the fuel itself and the investments required to build and maintain infrastructure, these additional costs will be borne by all customers, not just the data centers.
And third — perhaps most importantly — during periods of peak system stress like winter storms or summer heat waves, all this additional gas going to data centers will make price shocks more severe. In the case of Winter Storm Fern last January, for example, natural gas prices from Chicago to Boston were 19 to 42 times higher than the national average price from the prior year.
So, how can government officials prevent all this from happening? A Gas Customer Protection Pledge would fill the gaps in the already agreed upon objective not to raise energy cost for average customers. Mirroring the points from the Ratepayer Protection Pledge, here’s how that might work.
To address energy affordability in the long run, finite resources are best spent moving energy systems off fossil fuels to improve public health and reduce greenhouse gas emissions. In the meantime, we must make efforts today to control natural gas costs. America’s energy affordability crisis needs answers today, not down the road.
Now is the time for a Gas Customer Protection Pledge that builds out the other half of the commitment already made by hyperscalers and AI companies not to increase energy bills for other customers.
X-energy is vying against CNNC and Canada’s AtkinsRéalis.
For years now, the United States has watched anxiously as its nuclear industry stagnated while those of its biggest geopolitical adversaries boomed. Russia, America’s top 20th century rival, dominated exports, securing deals to build virtually every nuclear newcomer nation’s first reactors. China, meanwhile, took the lead in domestic construction, with three dozen large-scale reactors under construction right now; Beijing even dabbled briefly in exporting its technology with a deal to build half a dozen reactors in Pakistan. It’s already made an offer to build Serbia’s first nuclear plant, and it’s expected to bid on more deals soon.
Now, for the first time, an American company is going head to head with a Chinese state-owned champion for one of Asia’s most sought-after nuclear deals.
X-energy, the Amazon-backed reactor startup based in Maryland, is one of three companies to take part in a program with Singapore to the country’s regulators in its licensing department so they can see how an atomic power project goes from planning to approval. The goal is to help train the “nuclear manpower” needed to design a reactor buildout that matches Singapore’s unique needs, according to the name of the program. By observing the process to license reactors, the regulators from Singapore’s Ministry of Energy, Trade, and Industry and its Energy Market Authority hope to lay the groundwork for the city-state to import reactor technology and build its first nuclear plant.
Singapore spans less land area than the city of Memphis, Tennessee, yet the Southeast Asian city-state has plans to expand its electricity generating capacity by more than a quarter in the coming years to around 15 gigawatts — more than four times the U.S. city’s all-time high power demand. The country’s Ministry of Energy, Trade, and Industry and its Energy Market Authority will pay the salaries of its embedded workers for the full length of the program, anywhere from six months to two years. Aside from the free labor, the host companies receive an inside track to sell reactors to Singapore if the country moves forward with a nuclear project.
“They need to pick a technology that suits their very, very specific needs and constraints,” Miriam D'Onofrio, X-energy’s senior director of international markets, told me. (While the company announced the partnership at the Singapore International Energy Week summit late last month, X-energy spoke exclusively with Heatmap about the agreement.)
“We’re proud to be the only American entity — and one that wasn’t facilitated by the U.S. government at all,” she added. “That was something that Singapore evaluated for itself and made a central decision to pursue. That’s a testament to the strength of our technology and the trust that they have in us as a company.”
Another company vying for Singapore’s business is AtkinsRéalis, the Montreal-based nuclear company behind Canada’s homegrown CANDU reactor technology. But a source with direct knowledge of the Singaporean government’s thinking told me the country is already sold on the benefits of building a high-temperature gas-cooled reactor, an expensive option that promises a relatively small footprint on land and minimal risk of a meltdown. The CANDU, by contrast, is a pressurized heavy water reactor, which uses a special kind of water as a coolant to use raw uranium as a fuel and avoid enrichment altogether.
That means the real competition is between X-energy and the China National Nuclear Corporation. CNNC, the second of China’s two state nuclear companies, which currently operates the world’s only commercial high-temperature gas-cooled reactor. Located at Shidao Bay Nuclear Power Plant on the tip of the Shandong Peninsula that juts from northern China into the Yellow Sea, the demonstration reactor came online in December 2023. The completion of the 210-megawatt reactor, which runs on a specialized and fuel known as TRISO that’s specifically engineered for safety, vaulted China to the front of the global race for what are called fourth-generation technologies that use coolants other than water.
While the U.S., Britain, Germany, and Japan all built experimental high-temperature gas-cooled reactors (America also briefly operated a commercial plant in Colorado before shutting it down in the early 1990s due to high costs), China is the first in decades to actually pump its electricity onto the grid. Construction began earlier this month on a second such unit.
That could afford CNNC some advantages. “China has an HTGR that’s been operating,” D'Onofrio told me. “But it is demonstrably more difficult to get information out of China and on that program.”
The trouble is, countries that “are embarking on new nuclear programs want to learn and absorb themselves,” she said. “They don’t just want to buy something off the shelf,” she said. “That’s unfortunately not how nuclear works.” With the Xe-100, an 80-megawatt small modular reactor cooled with helium, D'Onofrio said, “we tried our best to optimize constructability, to optimize manufacturability, to optimize efficiencies in the core.”
X-energy is making progress. On Monday, the U.S. Nuclear Regulatory Commission granted the company a permit to begin construction on its first plant, a small facility on Texas’ Gulf coast to funnel electricity and heat to Dow’s second-largest chemical plant. X-energy has also inked at least two deals with American utilities for full-scale plants in Washington State, with Energy Northwest, and in Indiana with American Electric Power.
Though the company has yet to fully build one of its reactors, she said, “I am confident that once we do, there will be a wave that we’re excited to see of interest from industry, from data centers, and from customers all over the world.”
If China’s edge is having an actual operating reactor, the strongest argument for X-energy may be its plans to manufacture its own fuel.
Both the Chinese and the American reactors run on TRISO. Rather than slotting pellets of enriched uranium into PEZ dispenser-like fuel assemblies that go into conventional reactors, TRISO producers ball the enriched uranium into poppyseed-sized spheres coated in ceramic material. That coating absorbs the dangerous materials produced during fission and makes a meltdown physically impossible, eliminating the need for the massive steel and concrete domes that serve as containment in traditional nuclear plants.
While China fills its TRISO kernels with conventional low-enriched uranium, X-energy is manufacturing its own fuel out of a more potent type of fuel. That fuel, known as high-assay low-enriched uranium or HALEU, burns through more of the energy in the uranium, but it’s also more expensive, and the only major commercial vendor in the world today is Russia’s Rosatom.
“We have the [intellectual property] on some of the most reliable TRISO fabrication that’s ever been invented,” D'Onofrio said.
Some experts doubt that Singapore will actually commission a nuclear plant anytime soon. “The Singaporeans are treating nuclear energy as a long-term risk-monitoring exercise rather than an active engineering [project],” François Morin, the World Nuclear Association’s director in Beijing, told me in a text message. “For now, the state’s priority is maintaining a superficial, multi-directional radar so they aren’t blindsided if regional neighbors like Indonesia or Malaysia move forward with their own nuclear plans.”
While the appeal of a TRISO-fueled high-temperature gas-reactor is the absence of a multi-mile emergency planning zone like those that surround water-cooled plants, Morin said the Singaporean government is “ignoring the reality that no international regulator has universally codified a ‘zero-EPZ’ standard for a hyper-dense metropolitan area.”
X-energy said it doesn’t need to ultimately build a reactor in Singapore for the effort to be worthwhile.
“Even if Singapore doesn’t pursue an HTGR program — we’d love them to — they’re going to play a role in regional development,” D'Onofrio said. “We want to play a role in regional development, and the strength of Singaporean institutions — the ease of doing business here — makes it a really, really interesting option for us for a future footprint.”
