What the Council on Foreign Relations’ new climate program gets drastically wrong.

Let’s start with two basic facts.
First, the climate crisis is here now, killing people, devastating communities, and destroying infrastructure in Los Angeles and Asheville and Spain and Pakistan and China. And it will get worse.
Second, Donald Trump is the President of the United States. He began the process to withdraw the United States from the Paris Agreement on January 20, 2025, his first day in office in his second term. (He, of course, did this in his first term as well.) He illegally froze funding for climate programs that had passed and became law during the Biden administration, and his administration continues to ignore court orders to unfreeze these monies. He has signed numerous executive orders, including on reinvigorating clean [sic] coal, reversing state-level climate policies, “Zero-based regulatory budgeting to unleash American energy,” and “unleashing” American energy, the last of which revoked more than a dozen Biden era executive orders.
How do we address a world that is increasingly shaped by these two facts?
One attempt can be seen in the Council on Foreign Relations’s new “Climate Realism Initiative.” Its statement of purpose attempts to make climate action palatable to MAGA world by securitizing it, framing climate change as a foreign threat to Fortress America. It calls for investing in next-generation technologies and geoengineering in the hopes of leapfrogging the Chinese-led clean energy revolution that is beginning to decarbonize the world today is the best realistic way forward.
This attempt is doomed to failure. Real climate realism for the United States is to stop the destruction of American state capacity, and then to reflect and build on areas of core strength including finance and software.
CRI’s launch document does not call for the U.S. to reduce its own emissions. I’ll say that again: There is no call for the U.S. to reduce its own emissions in the essay establishing the mission and objectives of the Climate Realism Initiative. Written by Varun Sivaram, formerly chief strategy and innovation officer at wind energy developer Orsted and now the leader of the initiative, the essay proposes that four dug-in “fallacies” are getting in the way of effective policy-making: that climate change “poses a manageable risk” to the U.S.; that “the world’s climate targets are achievable;” that the clean energy transition is a “win-in for U.S. interests and climate action;” and that “reducing U.S. domestic greenhouse gas emissions can make a meaningful difference.” For Sivaram, the problem is always other places and their emissions.
He then goes on to propose three “pillars” of climate realism: the need for America to prepare for a world “blowing through climate targets;” to “invest in globally competitive clean technology industries;” and to “lead international efforts to avert truly catastrophic climate change.” How an America that does not commit to reduce its own emissions will have any credibility or standing to lead international efforts is left unstated.
Sivaram attempts to trick the reader into overlooking America’s emissions by ignoring the facts of the past and focusing instead on guesses about the future. It’s true that in 2023, China produced more than a quarter of new global carbon pollution — more than the United States, Europe, and India combined. But no country has contributed more to the blanket of pollution that traps additional heat in our atmosphere than the United States, which has emitted over 430 billion tons of CO2, or 23% of the world’s total historical emissions. Even in 2023, the U.S. remained the world’s number two carbon polluter.
Sivaram goes further than merely minimizing the U.S. role in creating our current climate problems. Indeed, he sets up climate change as a problem that foreign countries are imposing on Americans. “Foreign emissions,” he writes, “are endangering the American homeland,” and the effects of climate disasters “resemble those if China or Indonesia were to launch missiles at the United States.” There is something to this rhetoric that is powerful — we should think about climate-induced disasters as serious threats and respond to them with the kind of resources that we lavish on the military industrial complex. But the idea that it is foreign emissions that are the primary source of this danger is almost Trumpian.
The initiatives proposed in the Climate Realism launch are the initiatives of giving up. Investing in resilience and adaptation is needed in any scenario, but tying this spending on adaptation to Trumpian notions of protecting our borders reeks of discredited lifeboat ethics, which only cares to save ourselves and leaves others to suffer for our sins. And while supporting next-generation technologies is an appropriate piece of the policy puzzle, they should be like the broccoli at a steakhouse: off to the side and mostly superfluous compared with the meat and potatoes of deployment and mitigation to decarbonize today.
Sivaram may argue that there’s no point in trying to compete against China in the technologies of today when Chinese firms are so dominant and apparently willing to make these products while earning minimal profits. And from a parochial profit-maximizing perspective, there is a business case that firms should not be building lots of new solar cell manufacturing facilities given global manufacturing capacity.
But if American automotive firms simply ignore the coming EV wave and hope against hope that some breakthrough in solid state batteries will allow them to leapfrog over the firms vying today, they are fooling themselves. Electric vehicle giant BYD and world-leading battery manufacturer CATL have both announced batteries that can charge a car in five minutes. Both are also moving in the solid state space, and CATL is pushing into sodium ion batteries.
The notion that U.S. firms ought to sit out this fight for strategic reasons also ignores how China has come to dominate these sectors — by investing in today’s state of the art and pushing it forward through incremental process improvements at scale. The Thielian notion that “competition is for losers” leads to an immense amount of waste as wannabe founders search for unbreakable technological advantages. If venture capitalists want to fund such bets, I’m not going to stop them. But as a policy prescription for climate realism, it fails.
The final gambit of the essay is to advocate for America-controlled geoengineering. This, too, is an area where research may be needed. But regardless, it is the kind of emergency backup plan that you hope that you never need to use, rather than something that should be central to anyone’s policy strategy. Trump is currently decimating American capacity to research hard problems, whether they be cancer or vaccines or social science or anything else, so it is difficult to imagine that this administration is likely to spend real resources to investigate geoengineering.
The Climate Realism Initiative pitches itself as “bipartisan.” But where is the MAGA coalition that supports this? Even simple spending on adaptation and resilience seems unlikely to find much of a political home given the Trump administration’s drastic cuts in weather and disaster forecasting. Sivaram even mentions the need to balance the budget as part of climate realism, which must be a sick joke. For all of the fanfare over cuts to the federal government under Trump, the budget deficit is the last thing that they care about. Tax cuts remain the coin of the realm, with the House budgetary guidelines expanding the deficit by $2.8 trillion. Elon Musk’s Department of Government Efficiency, similarly, has a distorted notion of government efficiency, ignoring the returns to government investments and gutting the tax collection capacity of the IRS.
The Biden administration had plans — “all of the above” energy among them — that were coherent, if not necessarily the most appealing to the world. They were based on the idea that a resilient climate coalition in the U.S. required more than just deploying Chinese-made products.
CRI seems to want to engage instead in a fantasy conversation where anti-Chinese nationalism can unite Americans to fight climate change — an all-form, no-content negative sum realpolitik that does little to address the real, compelling, and deeply political questions that the climate crisis poses.
Alternative visions are possible. The American economy is services based. Americans and American firms will inevitably make some of the hardware components of the energy transition, but the opportunities that play to our strengths are mostly on the software side.
It is critical to remember that the clean technologies that power the energy transition are categorically different from the fossil fuels that the world burned (and still burns) for energy. We do not require a constant stream of these technologies to operate our economy. The solar panels on your roof or in the field outside of town still generate electricity even if you can’t buy new ones because of a trade war. Same with wind turbines. In fact, renewables are a source of energy security because the generation happens from domestic natural resources — the sun and wind. Yet smart thinkers like Jake Sullivan fall into the trap of treating “dependence” on Chinese renewable technologies as analogous to European dependence on Russian natural gas.
Even China’s ban on U.S.-bound rare earth exports won’t make much of a dent. Despite the name, rare earths aren’t that rare, and while China does dominate their processing, it’s a tiny industry; in making fun of the “critical” nature of rare earths, Bloomberg opinion writer Javier Blas noted that the total imports of rare earths from China to the U.S. in 2024 was $170 million, or about 0.03% of U.S.-China trade. That being said, the major concern is if supplies fall to zero then major processes that require tiny amounts of rare earths (like Yttria and turbine construction) could be completely halted with serious fallout.
The American government should carefully choose what industries it would like to support. Commodity factories that have little-to-no profits, like solar cells, seem unattractive. There are many more jobs in installing solar than there are in manufacturing it, after all.
On the other hand, sectors with a much larger existing domestic industry, such as wind turbines and especially automobiles, should not be left to wither. But rather than a tariff wall to protect them, the U.S. auto firms should be encouraged to partner with the leading firms — even if those firms are Chinese — to build joint ventures in the American heartland, so that they and the American people can participate in the EV shift.
But the core of real climate realism for the United States is not about new factories. It’s about playing to our strengths. The United States has the best finance and technology sectors in the world, and these should be used to help decarbonize at home and around the world. This climate realism agenda can come in left- and right-wing flavors. A leftist vision is likely state-led with designs, guides, and plans, while the right-wing vision relies on markets.
Take Texas. On May 7, 2020, the Texas grid set a record with 21.4 gigawatts of renewable electricity generation. Just five years later, that figure hit 41.9 gigawatts. Solar and batteries have exploded on the grid, with capacity hitting 30 gigawatts and 10 gigawatts respectively. They have grown so rapidly because of the state’s market-based system, with its low barriers to interconnection and competitive dynamics.
Of course, not every location is blessed with as much wind, sun, and open space as Texas. But there’s no reason why its market systems can’t be a template for other states and countries. This, too, is industrial policy — not just the factory workers building the technologies or even the installers deploying them. There is lots of work for the lawyers and power systems engineers and advertisers and policy analysts and bankers and consultants, as well.
Yet instead of seizing these real chances to push climate action forward at home and abroad, the Trump administration is eviscerating American state capacity, the rule of law, and global trust in the government. The whipsawing of Trump’s tariffs generates uncertainty that undercuts investment. The destruction of government support for scientific exploration hits at the next-generation moonshots that Sivaram is so enamored of, as well as the institutions that educate our citizens and train our workforce. Trump’s blatant disregard for court orders and his regime’s cronyism undercut belief in the rule of law, and that investments will rise and fall based on their economics rather than how close they are to the President.
But it’s not just Trump. Texas legislators are on the verge of destroying the golden goose of cheap electricity through rapid renewables deployment out of a desire to own the libs. Despite the huge economic returns to rural communities that have seen so much utility-scale expansion in the state, some Republican legislators are pushing bills that would stick their fingers into the electricity market pie, undercutting the renewable expansion and mandating expensive gas expansion.
The Trump business coalition, which was mostly vibes in the first place, is fracturing. There are conflicting interests between those who want to fight inflation and those who see low oil prices as a problem. Pushing down oil prices by pressuring OPEC+ to pump more crude and depressing global economic outlooks with the trade war (Degrowth Donald!) has hurt the frackers in Texas. Ironically, one way to lower their costs is to electrify operations, so they don’t have to rely on expensive diesel.
Climate change is here, but so is Donald Trump. Ignoring either one is a recipe for disaster as they both create destructive whirlwinds and traffic in uncertainty. The real solution to both is mitigation — doing everything possible today to stop as much of the damage as possible before it happens.

Representatives Jake Auchincloss and Mark Amodei want to boost “superhot” exploration.
Geothermal is about the only energy topic that Republicans and Democrats can agree on.
“Democrats like clean energy. Republicans like drilling. And everyone likes baseload power that is generated with less than 1% of the land and materials of other renewables,” Massachusetts Representative Jake Auchincloss, a Democrat, told me.
Along with Republican Representative Mark Amodei of Nevada, Auchincloss is introducing the Hot Rock Act on Friday, focusing specifically on “superhot” or “supercritical” geothermal resources, i.e. heat deposits 300 degrees Celsius or above. (Temperatures in large traditional geothermal resources are closer to 240 degrees.)
The bill — of which Heatmap got an exclusive early peek — takes a broad approach to supporting research in the sector, which is currently being explored by startups such as Quaise Energy and Mazama Energy, which in October announced a well at 331 degrees.
There’s superhot rock energy potential in around 13% of North America, modeling by the Clean Air Task Force has found — though that’s mostly around 8 miles below ground. The largest traditional geothermal facility in the U.S. is only about 2.5 miles at its deepest.
But the potential is enormous. “Just 1% of North America’s superhot rock resource has the potential to provide 7.5 terawatts of energy capacity,” CATF said. That’s compared to a little over a terawatt of current capacity.
Auchincloss and Amodei’s bill would direct the Department of Energy to establish “milestone-based research grant programs,” under which organizations that hit goals such as drilling to a specific depth, pressure, or temperature would then earn rewards. It would also instruct the DOE to create a facility “to test, experiment with, and demonstrate hot dry rock geothermal projects,” plus start a workforce training program for the geothermal industry.
Finally, it would grant a categorical exclusion from the National Environmental Policy Act for drilling to explore or confirm geothermal resources, which could turn a process that takes over a year into one that takes just a couple of months.
Geothermal policy is typically a bipartisan activity pursued by senators and House members from the Intermountain West. Auchincloss, however, is a New Englander. He told me that he was introduced to geothermal when he hosted an event in 2022 attended by executives from Quaise, which was born out of the Massachusetts Institute of Technology.
It turned out the company’s pilot project was in Nevada, and “I saw it was in Mark Amodei’s district. And I saw that Mark is on Natural Resources, which is the other committee of jurisdiction. And so I went up to him on the floor, and I was like, Hey there, you know, there's this company announcing this pilot,” Auchincloss told me.
In a statement, Amodei said that “Nevada has the potential to unlock this resource and lead the nation in reliable, clean energy. From powering rural communities and strengthening critical mineral production to meeting the growing demands of data centers, geothermal energy delivers dependable 24/7 power.”
Auchincloss told me that the bill “started from the simple premise of, How do we promote this technology?” They consulted climate and technology experts before reaching consensus on the milestone-based payments, workforce development, and regulatory relief components.
“I didn't have an ideological bent about the right way to do it,” Auchincloss said.
The bill has won plaudits from a range of industry groups, including the Clean Energy Buyers Association and Quaise itself, as well as environmental and policy organizations focused on technological development, like the Institute for Progress, Third Way, and the Breakthrough Institute.
“Our grassroots volunteers nationwide are eager to see more clean energy options in the United States, and many of them are excited by the promise of reliable, around-the-clock clean power from next-generation geothermal energy,” Jennifer Tyler, VP government affairs at the Citizens' Climate Lobby, said in a statement the lawmakers provided to Heatmap. “The Hot Rock Act takes a positive step toward realizing that promise by making critical investments in research, demonstration, and workforce development that can unlock superhot geothermal resources safely and responsibly.”
With even the Trump administration generally pro-geothermal, Auchincloss told me he’s optimistic about the bill’s prospects. “I expect this could command broad bipartisan support,” he said.
Plus a pre-seed round for a moon tech company from Latvia.
The nuclear headlines just keep stacking up. This week, Inertial Enterprises landed one of the largest Series A rounds I’ve ever seen, making it an instant contender in the race to commercialize fusion energy. Meanwhile, there was a smaller raise for a company aiming to squeeze more juice out of the reactors we already have.
Elsewhere over in Latvia, investors are backing an early stage bid to bring power infrastructure to the moon, while in France, yet another ultra-long-duration battery energy storage company has successfully piloted their tech.
Inertia Enterprises, yet another fusion energy startup, raised an eye-popping $450 million Series A round this week, led by Bessemer Venture Partners with participation from Alphabet’s venture arm GV, among others. Founded in 2024 and officially launched last summer, the company aims to develop a commercial fusion reactor based on the only experiment yet to achieve scientific breakeven, the point at which a fusion reaction generates more energy than it took to initiate it.
This milestone was first reached in 2022 at Lawrence Livermore National Laboratory’s National Ignition Facility, using an approach known as inertial confinement fusion. In this method, powerful lasers fire at a small pellet of fusion fuel, compressing it until the extremely high temperature and pressure cause the atoms inside to fuse and release energy. Annie Kritcher, who leads LLNL’s inertial confinement fusion program, is one of the cofounders of Inertia, alongside Twilio co-founder Jeff Lawson and Stanford professor Mike Dunne, who formerly led a program at the lab to design a power plant based on its approach to fusion.
The Inertia team plans to commercialize LLNL’s breakthrough by developing a new fusion laser system it’s calling Thunderwall, which it says will be 50 times more powerful than any laser of its type to date. Inertia isn’t the only player trying to commercialize laser-driven fusion energy — Xcimer Energy, for example, raised a $100 million Series A in 2024 — but with its recent financing, it’s now by far the best capitalized of the bunch.
As Lawson, the CEO of the new endeavor said in the company’s press release, “Our plan is clear: build on proven science to develop the technology and supply chain required to deliver the world’s highest average power laser, the first fusion target assembly plant, and the first gigawatt, utility-scale fusion power plant to the grid.” Great, but how soon can they do it? The goal, he says, is to “make this real within the next decade.”
In more nuclear news, the startup Alva Energy launched from stealth on Thursday with $33 million in funding and a proposal to squeeze more capacity out of the existing nuclear fleet by retrofitting pressurized-water reactors. The round was led by the venture firm Playground Global.
The startup plans to boost capacity by building new steam turbines and electricity generators adjacent to existing facilities, such that plants can stay online during the upgrade. Then when a plant shuts down for scheduled maintenance, Alva will upgrade its steam generator within the nuclear containment dome. That will allow the system to make 20% to 30% more steam, to be handled by the newly built turbine-generator system.
The company estimates that these retrofits will boost each reactor’s output by 200 megawatts to 300 megawatts. Applied across the dozens of existing facilities that could be similarly upgraded, Alva says this strategy could yield roughly 10 new gigawatts of additional nuclear capacity through the 2030s — the equivalent of building about 10 new large reactors.
Biden’s Department of Energy identified this strategy, known as “uprating”, as capable of adding 2 gigawatts to 8 gigawatts of new capacity to the grid. Alva thinks it can go further. The company promises to manage the entire uprate process from ensuring regulatory compliance to the procurement and installation of new reactor components. The company says its upgrades could be deployed as quickly as gas turbines are today — a five- to six-year timeline — at a comparable cost of around $1 billion per gigawatt.
Deep Space Energy, a Latvian space tech startup, has closed a pre-seed funding round to advance its goal of becoming a commercial supplier of electricity for space missions on the moon, Mars, or even deeper into space where sunlight is scarce. The company is developing power systems that convert heat from the natural decay of radioisotopes — unstable atoms that emit radiation as they decay — into electricity.
While it’s still very early-stage, this tech’s first application will likely be backup power for defense satellites. Long term, Deep Space Energy says it “aims to focus on the moon economy” by powering rovers and other lunar installations, supporting Europe’s goal of increasing its space sovereignty by reducing its reliance on U.S. defense assets such as satellites. While radioisotope generators are already used in some space missions, the company says its system requires five times less fuel than existing designs.
Roughly $400,000 of the funding came from equity investments from the Baltic-focused VC Outlast Fund and a Lithuanian angel investor. The company also secured nearly $700,000 from public contracts and grants from the European Space Agency, the Latvian Government, and a NATO program to accelerate innovation with dual-use potential for both defense and commercial applications.
As I wrote a few weeks ago, Form Energy’s iron-air battery isn’t the only player targeting 100-plus hours of low-cost energy storage. In that piece, I highlighted Noon Energy, a startup that recently demoed its solid-oxide fuel cell system. But there’s another company aiming to compete even more directly with Form by bringing its own iron-air battery to the European market: Ore Energy. And it just completed a grid-connected pilot, something Form has yet to do.
Ore piloted its 100-hour battery at an R&D center in France run by EDF, the state-owned electric utility company. While the company didn’t disclose the battery’s size, it said the pilot demonstrated its ability to discharge energy continuously for about four days while integrating with real-world grid operations. The test was supported by the European Union’s Storage Research Infrastructure Eco-System, which aims to accelerate the development of innovative storage solutions, and builds on the startup’s earlier grid-connected installation at a climate tech testbed in the Netherlands last summer.
Founded in 2023, Ore plans to scale quickly. As Bas Kil, the company’s business development lead, told Latitude Media after its first pilot went live, “We’re not planning to do years and years of pilot-scale [projects]; we believe that our system is now ready for commercial deployment.” According to Latitude, Ore aims to reach 50 gigawatt-hours of storage per year by 2030, an ambitious goal considering its initial grid-connected battery had less than one megawatt-hour of capacity. So far, the company has raised just shy of $30 million to date, compared to Form’s $1.2 billion.
Battery storage manufacturer and virtual power plant operator Sonnen, together with the clean energy financing company Solrite, have launched a Texas-based VPP composed exclusively of home batteries. They’re offering customers a Solrite-owned 60-kilowatt-hour battery for a $20 monthly fee, in exchange for a fixed retail electricity rate of 12 cents per kilowatt-hour — a few cents lower than the market’s average — and the backup power capability inherent to the system. Over 3,000 customers have already enrolled, and the companies are expecting up to 10,000 customers to join by year’s end.
The program is targeting Texans with residential solar who previously sold their excess electricity back to the grid. But now that there’s so much cheap, utility-scale solar available in Texas, electricity retailers simply aren’t as incentivized to offer homeowners favorable rates. This has left many residents with “stranded” solar assets, turning them into what the companies call “solar orphans” in need of a new way to make money on their solar investment. Customers without rooftop solar can participate in the program as well, though they don’t get a catchy moniker.
Current conditions: New Orleans is expecting light rain with temperatures climbing near 90 degrees Fahrenheit as the city marks the 20th anniversary of Hurricane Katrina • Torrential rains could dump anywhere from 8 to 12 inches on the Mississippi Valley and the Ozarks • Japan is sweltering in temperatures as high as 104 degrees.
President Donald Trump has done what he didn’t dare attempt during his first term, repealing the finding that provided the legal basis for virtually all federal regulations to curb greenhouse gas emissions. By rescinding the 2009 “endangerment finding,” which established that planet-heating emissions harm human health and therefore qualify for restrictions under the Clean Air Act, the Trump administration hopes to unwind all rules on pollution from tailpipes, trucks, power plants, pipelines, and drilling sites all in one fell swoop. “This is about as big as it gets,” Trump said alongside Environmental Protection Agency Administrator Lee Zeldin at a White House event Thursday.
The repeal, which is sure to face legal challenges, opens up what Reuters called a new front in the legal wars over climate change. Until now, the Supreme Court had declined to hear so-called public nuisance cases brought by activists against fossil fuel companies on the grounds that the legal question of emissions was being sorted out through federal regulations. By eliminating those rules outright, litigants could once again have new standing to sue over greenhouse gas emissions. To catch up on the endangerment finding in general, Heatmap’s Robinson Meyer and Emily Pontecorvo put together a handy explainer here.
A bill winding its way through Ohio’s Republican-controlled state legislature would put new restrictions on development of wind and solar projects. The state already makes solar and wind developers jump over what Canary Media called extra hurdles that “don’t apply to fossil-fueled or nuclear power plants, including counties’ ability to ban projects.” For example, siting authorities defer to local opposition on renewable energy but “grant opponents little say over where drilling rigs and fracking waste can go.”
The new legislation would make it state policy “in all cases” for new power plants to “employ affordable, reliable, and clean energy sources.” What qualifies as “affordable, reliable, and clean”? Pretty much everything except wind and solar, potentially creating a total embargo on the energy sources at any utility scale. The legislation mirrors a generic bill promoted to states by the American Legislative Exchange Council, a right-wing policy shop.

China’s carbon dioxide emissions fell by 1% in the last three months of 2025, amounting to a 0.3% drop for the full year. That’s according to a new analysis by Carbon Brief. The decline extends the “flat or falling” trend in China’s emissions that started in March 2024 and has now lasted nearly two years. Emissions from fossil fuels actually increased by 0.1%, but pollution from cement plunged 7%. While the grid remains heavily reliant on coal, solar output soared by 43% last year compared to 2024. Wind grew by 14% and nuclear by 8%. All of that allowed coal generation to fall by 1.9%.
At least one sector saw a spike in emissions: Chemicals, which saw emissions grow 12%. Most experts interviewed in Heatmap’s Insiders Survey said they viewed China has a climate “hero” for its emissions cuts. But an overhaul to the country’s electricity markets yielded a decline in solar growth last year that’s expected to stretch into this year.

Rivian Automotive’s shares surged nearly 15% in after-hours trading Thursday when the electric automaker announced earnings that beat Wall Street’s expectations. While it cautioned that it would continue losing money ahead of the launch of its next-generation R2 mid-size SUV, the company said it would deliver 62,000 to 67,000 vehicles in 2026, up 47% to 59% compared with 2025. Rivian CEO RJ Scaringe told CNBC that the R2 would make up the “majority of the volume” of the business by the end of next year. He told investors 2025 was a “foundational year” for the company, but that 2026 would be “an inflection point.”
Another clean energy company is now hot on the stock market. SOLV Energy, a solar and battery storage construction contractor, secured market capitalization eclipsing $6 billion in the two days since it started trading on the Nasdaq. The company, according to Latitude Media, is “the first pure-play solar and storage” company in the engineering, procurement, and construction sector of the industry to go public since 2008.

Israel has never confirmed that it has nuclear weapons, but it’s widely believed to have completed its first operating warhead in the 1960s. Rather than give up its strategic ambiguity over its arsenal, Israel instead forfeited the development of civilian nuclear energy, which would have required opening up its weapons program to the scrutiny of regulators at the United Nations’ International Atomic Energy Agency. That apparently won’t stop the U.S. from building a reactor in Israel to power a joint industrial complex. Washington plans to develop a campus with an advanced microchip factory and data centers that would be powered by a small modular reactor, NucNet reported. So-called SMRs have yet to be built at a commercial scale anywhere in the world. But the U.S. government is betting that smaller, less powerful reactors purchased in packs can bring down the cost of building nuclear plants and appeal to fearful skeptics as a novel spin on the older technology.
In reality, SMRs are based on a range of designs, some of which closely mirror traditional, large-scale reactors but for the power output, and a growing chorus of critics say the economies of scale are needed to make nuclear projects pencil out. But the true value of SMRs is for off-grid power. As I wrote last week for Heatmap, if the U.S. government wants it for some national security concern, the price doesn’t matter as much.
Of all the fusion companies racing to build the first power plant, Helion’s promise of commercial electricity before the end of the decade has raised eyebrows for its ambition. But the company has hit a milestone. On Friday morning, Helion’s Polaris prototype became the first privately developed fusion reactor to use a deuterium-tritium fuel source. The machine also set a record with plasma temperatures 150 million degrees Celsius, smashing its own previous record of 100 million degrees with an earlier iteration of Helion’s reactor.
