Vermont’s natural gas company is selling heat pumps and rebranding itself a “thermal service provider.”

On a recent Friday morning, I sat down to watch a webinar about a natural gas utility and unexpectedly found myself glued to the screen.
The video featured Morgan Hood, the new product development manager at a small utility once called Vermont Gas Systems, now known simply as VGS, that serves about 55,000 customers in its titular state. For 80 minutes Hood described how the company was working to reinvent itself as a “thermal solutions provider.” As part of that mission, it had recently started selling and leasing electric heat pump water and space heaters to its customers to help them reduce their gas use.
As a reporter who has covered natural gas utilities’ expansion plans and the industry’s all-out war on electrification, I was stunned. The programs alone were unusual, but what surprised me more was the way Hood talked about them.
“If we want to continue to serve our customers, which we do, significant changes are necessary,” she said, describing a “dramatic shift” in public sentiment toward natural gas in Vermont. “We know we're not going to be expanding our customer base with natural gas customers in the future.”
It’s hard to overstate how different Hood’s tone and message were from that of the average gas utility executive, who tends to highlight their product’s popularity and make a case for its role in a low-carbon future. Consider the remarks of Kim Greene, the CEO of the much larger Southern Company Gas, at a conference I attended in November. “Natural gas is foundational to America's clean energy future," she told an audience of state regulators. Without ever once acknowledging that natural gas contributes to climate change, she went on to describe it as a “magical molecule” that was important to the company’s decarbonization strategy.
When I later probed climate advocates in Vermont about VGS, I learned that many dismiss the company’s image change as greenwashing, or are at least skeptical of its plans. They pointed to a highly contested $165 million pipeline the company recently built, and a controversial plan to replace the fuel in its pipelines with biogas and hydrogen.
But my initial impressions also weren’t unfounded. The company does in fact seem to be unique in the way it has actively started leaning into the shift that science, policy, and economics are all driving toward — a transition to all-electric buildings.
“VGS is among the most progressive gas utilities in the country, there's no question about that,” Ben Walsh, the climate and energy program director at the Vermont Public Interest Research Group, and a longtime critic of VGS, told me.
The company still has a lot to figure out. Hood was remarkably transparent in acknowledging that the new products VGS is offering aren’t nearly as profitable as selling natural gas. But its recent past and its uncertain future make it a revealing case study of the challenges gas companies face in trying to stay viable as they try to decarbonize.
The webinar, titled “A Gas Utility Goes Electric,” was organized by a Portland, Oregon-based advocacy group called Electrify Now. Its co-founder Brian Stewart told me he initially had some reservations about featuring a gas utility in their event series, but he and his partners were impressed with the company’s interest in engaging with an electrification group. They hoped the talk might reveal a model that other utilities could follow — particularly Northwest Natural, their local gas utility in Oregon.
“They're doing the exact opposite of what VGS is at least attempting to do,” Stewart said. “Northwest Natural is still denying the idea that electrification is even better from an emissions standpoint.”
In fact, Northwest Natural is not just denying it — it’s reportedly putting millions of dollars into opposing electrification. In February, the Oregon city of Eugene passed an ordinance banning gas hookups in new residential buildings. Northwest Natural responded by spending more than $900,000 to get a measure to overturn the gas ban on the city’s November ballot, according to campaign finance records reviewed by The Washington Post. And it’s just getting started. The Post obtained audio indicating that the gas industry plans to spend $4 million on the Eugene referendum.
The strategy has been widely adopted by the gas industry. Last year, a utility in Southern California, SoCalGas, was fined $10 million for spending ratepayer funds to fight stronger building efficiency standards that would have reduced natural gas demand. New York Focus reported last week that National Fuel, a gas utility in Western New York, is spending hundreds of thousands of ratepayer dollars to lobby against a statewide push to reduce natural gas use.
VGS, on the other hand, first signaled it was reading the writing on the wall for natural gas in 2019, when it announced a new strategy to eliminate its greenhouse gas emissions by 2050.
That was around the time state leaders were contemplating a new climate law called the Global Warming Solutions Act, which passed the following year. VGS hired a new CEO, Neale Lunderville, who reorganized the company, creating new positions focused on decarbonization, including Hood’s role. Richard Donnelly, who spent a decade working for a nonprofit utility dedicated to energy efficiency joined VGS as its Director of Energy Innovation.
“The creation of that job was a clear signal to me that they were investing in the right things,” Donnelly told me.
VGS rolled out its first electrification program in early 2022, offering customers the option to lease or buy heat pump water heaters. The company was in a fairly unique position to do this, as it already had a sales and leasing program for gas equipment and an in-house team trained to install heating equipment.
Then, a couple of weeks ago, VGS launched an electric space heating program, offering central heat pumps that utilize the same ductwork as a homeowner’s existing furnace. For now, the company is installing these as dual fuel systems, meaning recipients keep their gas furnaces as a back-up source of heat. While heat pumps designed for cold climates don’t require this, they do lose efficiency in the coldest temperatures. Customers can decide when they want the system to switch over to gas, and the company developed a calculator that shows them how much carbon they can save, and what the anticipated costs will be, depending on where they set the switchover point.
The space heating systems are only available to a portion of the company’s customers — about 40% — because most have boilers and radiators with no ductwork. Hood said they hope to offer electric options for those homes in the future.
Dylan Giambatista, director of public affairs for VGS, told me the program is already taking off. Two weeks after it launched, they had well over 100 inquiries, he said. The water heaters, on the other hand, have had a pretty slow start. Only about 6% — or 48 total — of the water heaters the company has installed since January 2022 were heat pumps. “I don't think that folks are yet aware of that technology,” he said. “We expect heat pump water heater use will increase over time as incentives and consumer awareness increase,” he added in an email later.
Electrification isn’t the company’s only strategy to meet Vermont’s emissions goals.
It’s trying to reduce customers’ total energy usage through weatherization and other home efficiency improvements.
It’s also investing in alternative fuels, like renewable natural gas and hydrogen, to pump through its pipelines to any remaining gas customers. Nearly two-thirds of the gas that VGS sells is delivered to commercial and industrial customers, not all of whom may be able to fully electrify their operations. But local climate advocates have a lot of concerns about that aspect of the plan. Renewable natural gas, which typically comes from decomposing waste or dairy manure, is a lot more expensive than fossil gas. There’s also research indicating that it doesn’t necessarily have the climate benefits that proponents claim.
While Walsh, of the Public Interest Research Group, acknowledged how unique VGS’ electrification programs were, he said it's way too early to give the company the benefit of the doubt.
“There are some strategies that a gas utility could implement, that on the surface look good, but ultimately don't serve Vermont,” he said. “I think it's incumbent on all of us that are focused on cutting carbon pollution and cutting energy costs for Vermonters to watchdog their efforts very closely as they unfold.”
Others discount VGS’ heat pump programs because the company also continues to market and sell gas equipment and hook up new gas customers. Annette Smith, who runs a group called Vermonters for a Clean Environment sent me a screenshot of a VGS Facebook ad from May 8 offering people $500 to switch to natural gas.
Jim Dumont, a lawyer who has represented opponents of VGS in regulatory cases and lawsuits for years, said the first thing the company has to do to win public trust is come clean. “They have to tell the public that burning gas to heat your homes is helping push us over the climate cliff,” he told me. “They can sell heat pumps, but it's a competing message.”
VGS doesn’t deny that natural gas contributes to climate change. Lunderville, the CEO, told Vermont officials in a 2021 letter that the company recognizes “that its principal product today — fossil gas — has significant climate impacts.”
But the message stings with irony to Dumont, who has spent the last decade fighting a 41-mile gas pipeline the company built prior to its come-to-Jesus moment. Back in 2013, when VGS was first seeking approval for the pipeline from regulators, it argued that the project would cut energy costs and carbon emissions in the state. Most Vermonters did, and still do, heat their homes with fuel oil, propane, or wood — and gas can be a cleaner and often cheaper option. But opponents argued that cold climate heat pumps that were coming on to the market would be more affordable and effective.
Cold climate heat pumps were still pretty new at the time, and certainly weren’t being adopted in Vermont yet. The idea was sidelined, and while the scale of the pipeline was ultimately reduced, its cost ballooned from $86 million to $165 million. And now that it's completed, VGS is marketing heat pumps.
To Dumont, that’s not only ironic, it’s worrisome. The way gas utilities like VGS pay for big pipeline projects is to recover the costs over decades through customer bills. But if VGS helps people go electric, the residual costs of the pipeline are going to fall on fewer and fewer customers. As VGS leans into electrification, it could also be barreling toward a scenario referred to as the utility death spiral: the cost of gas will increase, driving more people to get off it.
“Is the public going to be asked to bail out the company, or will the company be responsible for its own bad judgment and will its sole shareholder have to swallow the loss?” Dumont asked. “If there are no consequences for making a bad investment, then effectively it's not a regulated utility, it's effectively a taxpayer-funded business.”
This is a problem that all gas utilities are facing or will likely face, whether or not they embrace a transition to electric buildings. Mike Henchen, a principle in the carbon-free buildings program at RMI, a national nonprofit, said this was “the elephant in the room” around the country.
“How to deal with all the customers hooked up to this fossil fuel system looms large on the horizon,” he said. “There's not going to be an easy way to tackle that.”
I reached out to Énergir, the Canadian company that owns VGS, to find out whether it had any concerns about VGS’ financial future. “Énergir has always believed in the complementarity of different energy solutions and in accelerating electrification where it makes sense,” Éric Lachance, president and CEO of Énergir said by email, adding that “Énergir strongly supports VGS’s approach.”
Though heat pumps aren’t as profitable as natural gas, the company does see opportunities for growth. It can sell and lease the water heaters to residents outside its existing customer base. It’s also exploring the potential to build and manage geothermal heating networks, where entire neighborhoods could be heated by underground pipes carrying nothing but water.
“The market opportunity is huge,” said Donnelly, the Director of Energy Innovation. For now, the company is primarily limited by staffing, and is being careful not to create more demand than it can fulfill. He estimated VGS was looking at “hundreds of installs over the next couple of years and growing that part of our business quite rapidly, hopefully, within the next five years.”
VGS also sees potential for these programs to become more profitable thanks to a law passed by the state legislature earlier this month called the Affordable Heat Act that directs the state’s utility regulators to design a clean heat standard. The company could eventually earn credits for its electrification programs and sell them to other fuel providers in the state that need to comply with the standard.
As policy and technology continue to evolve, it makes sense that VGS doesn’t know exactly what the future holds. But faced with similar uncertainty, most gas utilities have responded by putting their heads in the sand or fighting tooth and nail against change.
What makes VGS remarkable is that it’s at least trying to find its place in a post-gas world.

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: It looks like rain on Valentine’s Day across the South • Storm Nils is battering France with heavy rain and gales of up to 100 miles per hour • A Northeast Monsoon, known locally as an Amihan, is flooding the northern Philippine island of Luzon, threatening mudslides.
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.
