On supersonic gas, space solar, and Japanese fusion

Current conditions: The Pacific Northwest’s second atmospheric river in a row is set to pour up to 8 inches of rain on Washington and Oregon • A snow storm is dumping up to 6 inches of snow from North Dakota to northern New York • Warm air is blowing northeastward into Central Asia, raising temperatures to nearly 80 degrees Fahrenheit at elevations nearly 2,000 feet above sea level.
Heatmap’s Jael Holzman had a big scoop last night: The three leading Senate Democrats on energy and permitting reform issues are a nay on passing the SPEED Act. In a joint statement shared exclusively with Jael, Senate Energy and Natural Resources ranking member Martin Heinrich, Environment and Public Works ranking member Sheldon Whitehouse, and Hawaii senator Brian Schatz pledged to vote against the bill to overhaul the National Environmental Policy Act unless the legislation is updated to include measures to boost renewable energy and transmission development. “We are committed to streamlining the permitting process — but only if it ensures we can build out transmission and cheap, clean energy. While the SPEED Act does not meet that standard, we will continue working to pass comprehensive permitting reform that takes real steps to bring down electricity costs,” the statement read. To get up to speed on the legislation, read this breakdown from Heatmap’s Emily Pontecorvo.

In June, Heatmap’s Matthew Zeitlin explained how New York State was attempting to overcome the biggest challenge to building a new nuclear plant — its deregulated electricity market — by tasking its state-owned utility with overseeing the project. It’s already begun staffing up for the nuclear project, as I reported in this newsletter. But it’s worth remembering that the New York Power Authority, the second-largest government-controlled utility in the U.S. after the federal Tennessee Valley Authority, gained a new mandate to invest in power plants directly again when the 2023 state budget passed with measures calling for public ownership of renewables. On Tuesday, NYPA’s board of trustees unanimously approved a list of projects in which the utility will take 51% ownership stakes in a bid to hasten construction of large-scale solar, wind, and battery facilities. The combined maximum output of all the projects comes to 5.5 gigawatts, nearly double the original target of 3 gigawatts set in January.
But that’s still about 25% below the 7 gigawatts NYPA outlined in its draft proposal in July. What changed? At a hearing Tuesday morning, NYPA officials described headwinds blowing from three directions: Trump’s phaseout of renewable tax credits, a new transmission study that identified which projects would cost too much to patch onto the grid, and a lack of power purchase agreements from offtakers. One or more of those variables ultimately led private developers to pull out at least 16 projects that NYPA would have co-owned.

During World War II, the Lionel toy train company started making components for warships, the Ford Motor Company produced bomber planes, and the Mattatuck Manufacturing Company known for its upholstery nails switched to churning out cartridge clips for Springfield rifles. In a sign of how severe the shortfall of equipment to generate gas-powered electricity has become, would-be supersonic jet startups are making turbines. While pushing to legalize flights of the supersonic jets his company wants to build, Blake Scholl, the chief executive of Boom Supersonic, said he “kept hearing about how AI companies couldn’t get enough electricity,” and how companies such as ChatGPT-maker OpenAI “were building their own power plants with large arrays of converted jet engines.” In a thread on X, he said that, “under real world conditions, four of our Superpower turbines could do the job of seven legacy units. Without the cooling water required by legacy turbines!”
The gas turbine crisis, as Matthew wrote in September, may be moving into a new phase as industrial giants race to meet the surging demand. In general, investors have rewarded the effort. “But,” as Matthew posed, “what happens when the pressure to build doesn’t come from customers but from competitors?” We may soon find out.
It is, quite literally, the stuff of science fiction, the kind of space-based solar power plant that Isaac Asimov imagined back in 1940. But as Heatmap’s Katie Brigham reported in an exclusive this morning, the space solar company Overview Energy has emerged from stealth, announcing its intention to make satellites that will transmit energy via lasers directly onto Earth’s power grids. The company has raised $20 million in a seed round led by Lowercarbon Capital, Prime Movers Lab, and Engine Ventures, and is now working toward raising a Series A. The way the technology would work is by beaming the solar power to existing utility-scale solar projects. As Katie explained: “The core thesis behind Overview is to allow solar farms to generate power when the sun isn’t shining, turning solar into a firm, 24/7 renewable resource. What’s more, the satellites could direct their energy anywhere in the world, depending on demand. California solar farms, for example, could receive energy in the early morning hours. Then, as the sun rises over the West Coast and sets in Europe, ‘we switch the beam over to Western Europe, Morocco, things in that area, power them through the evening peak,’” Marc Berte, the founder and CEO of Overview Energy, told her. He added: “It hits 10 p.m., 11 p.m., most people are starting to go to bed if it’s a weekday. Demand is going down. But it’s now 3 p.m. in California, so you switch the beam back.”
In bigger fundraising news with more immediate implications for our energy system, next-generation geothermal darling Fervo Energy has raised another $462 million in a Series E round to help push its first power plants over the finish line, as Matthew wrote about this morning.
When Sanae Takaichi became the first Japanese woman to serve as prime minister in October, I told you at the time how she wanted to put surging energy needs ahead of lingering fears from Fukushima by turning the country’s nuclear plants back on and building more reactors. Her focus isn’t just on fission. Japan is “repositioning fusion energy from a distant research objective to an industrial priority,” according to The Fusion Report. And Helical Fusion has emerged as its national champion. The Tokyo-based company has signed the first power purchase agreement in Japan for fusion, a deal with the regional supermarket chain Aoki Super Co. to power some of its 50 stores. The Takaichi administration has signaled plans to increase funding for fusion as the new government looks to hasten its development. While “Japan still trails the U.S. and China in total fusion investment,” the trade newsletter reported, “the policy architecture now exists to close that gap rapidly.”
Another day, another emerging energy or climate technology gets Google’s backing. This morning, the carbon removal startup Ebb inked a deal with Google to suck 3,500 tons of CO2 out of the atmosphere. Ebb’s technology converts carbon dioxide from the air into “safe, durable” bicarbonate in seawater and converting “what has historically been a waste stream into a climate solution,” Ben Tarbell, chief executive of Ebb, said in a statement. “The natural systems in the ocean represent the most powerful and rapidly scalable path to meaningful carbon removal … Our ability to remove CO2 at scale becomes the natural outcome of smart business decisions — a powerful financial incentive that will drive expansion of our technology.”

Robotaxis are more likely to be EVs, and that’s not a coincidence.
Here in Los Angeles, the hot new thing in parenting is Waymo. One recent article argued that driverless electric vehicles have become the go-to solution for overscheduled parents who can’t be everywhere at once. No time to drive the kid to school dropoff or to practice? Hire a rideshare, preferably one without a potentially problematic human driver.
Perhaps it’s fitting that younger Americans, especially, are encountering electric cars in this way. Over the past few years, plenty of headlines have declared that teens and young adults have fallen out of love with the automobile; they’re not getting their driver’s licenses until later, if at all, and supposedly aren’t particularly keen on car ownership compared to their parents and grandparents. Getting around in a country built for the automobile leaves them more reliant on the rideshare industry — which, it so happens, is a place where the technological trends of electric and autonomous vehicles are rapidly converging.
This isn’t the way most people, myself included, talk about the EV revolution. That discourse typically runs through the familiar lens of our personal vehicles — which, it should be noted, Americans still lease or buy in the millions. In that light, EVs are struggling. Since buyers raced to scoop up electric cars in September before the federal tax credit lapsed, sales have slowed. Automakers have canceled or delayed numerous models and pivoted back to combustion engines or hybrids in response to the hostile Trump-era environment for selling EVs. While the world has carried on with electrification, America has backslid.
While all this was happening, however, the rideshare industry was accelerating in the opposite direction. Waymo’s fleet of autonomous vehicles is all-electric, currently made up of Jaguar I-Pace SUVs. Uber just invested more than $1 billion in Rivian as part of a plan to add thousands of the brand’s new R2 EVs to its fleet of electric robotaxis. Tesla’s moves are particularly telling. Elon Musk is still selling plenty of normal, human-driven Model Y and Model 3 EVs to make some money for the moment, but the company’s future prospects are all-in on the Cybercab, a two-seater robotaxi that would never be driven by a person. Who’d buy such a thing? Rideshare companies — or, perhaps, people see the Cybercab as a passive income machine that shuttles their neighbors around town whenever they’re not riding in it.
Human-driven rideshare fleets are quickly electrifying, too. Uber now allows riders to request an EV explicitly, an option that has been growing in popularity, especially as rising gas prices make electric rides more appealing. The company has been offering thousands of dollars of incentives to drivers who want to buy an EV, a program that expanded nationwide this month. EV-maker Fisker went bankrupt and folded, but its orphaned Ocean vehicles are roaming New York City as rideshare cars. Sara Rafalson of the charging company EVgo recently told me that rideshare already accounts for a quarter of the energy it distributes.
Yes, gasoline carries certain advantages for a taxi service — a gas-burning cab can drive all night with just momentary refueling stops, for example, whereas an EV must go out of commission during its occasional charging stops. Nevertheless, it’s clear that the rideshare industry is going electric.
That isn’t just because EVs have a futuristic vibe. There are technological reasons, too. Tesla and Rivian have designed their vehicles to be effectively smartphones on wheels, which makes them ideally suited for robotaxis. EVs have plenty of battery power on hand to meet all the computational demands of self-driving. Plus, electric power is particularly efficient for stop-and-go urban driving.
On the EV side, the business case for electric robotaxis is particularly compelling. One reason electric cars have struggled with everyday Americans is that it’s more difficult for an individual to stomach the higher upfront cost of an EV to enjoy its longer-term rewards. That’s less true for a business, whose accountants know EVs mean less long-term maintenance.
In the case of the rideshare economy, EVs are becoming the clear choice even though they’re owned by individual drivers. While the EV purchasing tax credit is gone for individuals, drivers can get financial help from a company like Uber to purchase an EV, which allows them to insulate themselves from the volatility of gas prices and reduce their regular maintenance schedule. They can also charge strategically around their taxi trips; robotaxi fleets often concentrate their recharging to the overnight hours when electricity is cheapest.
There is plenty of evidence that the “Gen Z doesn’t want to own cars” narrative is as reductive and oversimplified as you’d think. Younger generations are interested in cars — and in electric cars, in particular — but they’re often put off by the soaring costs of owning and maintaining a vehicle. As EV prices continue to fall, you can expect EV adoption to accelerate among Gen Z and millennial drivers.
In the meantime, those folks don’t have to buy an EV to join the EV age. It’s getting more and more likely that the car that drives you to the airport will be an EV — and more likely that riders will opt for electric if given the choice.
$4 of gasoline will actually get you pretty far these days.
Everyone’s mad about high oil prices, but are they doing anything about it? With around 11 million barrels per day (about a tenth of global production) shut in, and thus missing from the global oil market, someone has to be using less of it. Maybe it’s petrochemical plants that run on tight margins slowing down. Maybe it’s European airlines cancelling flights.
At least so far, it’s probably not American drivers.
“In the U.S. we’re seeing an indifference, in terms of what we can see from consumption numbers,” David Doherty, head of natural resources research at BloombergNEF, told me on the sidelines of the research group’s annual summit last week. The Energy Information Administration’s proxy for gasoline consumption, “product supplied of finished motor gasoline,” shows no dramatic change following the beginning of the war or subsequent spike in oil prices.
Gas prices in the United States sit at $4.11 per gallon according to AAA, compared to $3.15 a year ago. But even in the context of the almost $5 per gallon in 2022 and the $4.11-ish gas hit in the summer of 2008, the impact on actual households is likely more mild.
“$4 now is very different to $4 five years ago. And it's definitely different to $4 in 2008, which is when the last price spikes came through,” Doherty said. “$4 doesn't get you a coffee now. $4 a decade ago got you coffee plus oat milk.”
For one, a dollar is hardly a dollar anymore. There’s been higher than typical inflation since 2022, and a substantial rise in overall prices since 2008. This means that a dollar of gasoline (or even $4) is taking up a smaller portion of American consumer spending than it has in the past.
Looking back even further, the American auto fleet has gotten more efficient, meaning that drivers are getting more miles per gallon — and thus miles per dollar — than they were in the past. And that’s not even taking into account the rise of electric vehicles, which allow drivers to opt out of gasoline price volatility altogether.
Ironically, a big chunk of the credit comes from the now essentially scrapped Corporate Average Fuel Economy standards — themselves a response to the 1973 oil shock and designed to ease the American auto fleet’s dependency on fuels with volatile prices set by the global market by ratcheting up fuel economy over time. Then in 2007, President George W. Bush signed into law the first major tightening of CAFE standards in nearly 30 years.
“CAFE standards — which have just been neutered — ultimately have helped,” Doherty told me, referring to the Trump administration’s successful efforts to undo further fuel economy progress under the Obama and Biden administrations.
Overall, the U.S. economy has also gotten less “oil intensive” — we simply use less oil per dollar of economic activity than we used to. Since 1970, oil consumption has gone up by about 20%, while the size of the economy as measured in GDP has more than quadrupled.
When it comes to how the changing price of oil, and thereby gasoline, affects drivers, it’s a little trickier. I decided to calculate the “miles per dollar” on an annual basis, and then conservatively estimated how fleet efficiency would have increased by now.
To do this, I looked at the average miles per gallon of the U.S. car fleet and the “all grades” gasoline price for those same years. (“All grades” a little higher than the typical “regular” gas series, but the data goes back further.) The MPG data only goes back to 2024, so I conservatively projected it out to this year. While U.S. drivers are getting less out of their dollar than they did in 2024, they’re also going farther than they did in 2022 and 2008, the last time gas prices spiked dramatically.
I also wanted to get an idea of how much household spending is on gasoline. There’s no perfect way to do this with up-to-date data, but I was able to look at the relative importance of transportation fuel in the Consumer Price Index, which tells you the portion of spending on gasoline among the goods and services tracked by the Bureau of Labor Statistics. As expected, the relative importance rose dramatically in the 1970s and early 1980s, and hit a new high in 2007; in 2025, it fell close to its all time lows at just under 3%.
The Bureau of Labor Statistics also looks at annual household spending on gasoline. The latest data from 2024 agreed that it had been falling, from $2,805 in 2022, to $2,449 in 2023, and then $2,411 in 2024, but the 2025 data isn’t available yet.
Looking at more frequently updated data, the Republican staff of the Joint Economic Committee estimated that spending in February on “gasoline and other energy goods” was just over 1.9% of all personal consumption, a more than 0.2 percentage point decline from a year ago. This was, of course, before gasoline prices soared in March and into April.
“If you were to put [gasoline] beside the cost of your rent, for example, it's becoming a much smaller slice of your outlays,” Doherty said. This is the now-abandoned fuel efficiency standards actually working, Doherty said. “It's a different share of your budget. It's a more efficient car, and that’s through design.”
This also helps explain why in the United States, we’re not seeing the “demand destruction” that should accompany a contraction in oil supply, where consumers cut back consumption in response to high prices.
But with lines of empty tankers queuing up at the United States’ Gulf Coast petroleum export complex, looking to bring American crude to markets that can’t get their hands on oil from the Persian Gulf, prices may still have a way to go. Drivers in the United States are now in a barrel-for-barrel competition with the rest of the world.
On China’s fossil fuel controls, Maine data centers, and a faster NRC
Current conditions: Nearly two dozen states from Texas to Minnesota are bracing for days of thunderstorms, tornadoes, hail, and winds up to 70 miles per hour • Japan is deploying 1,400 firefighters to battle a wildfire in Iwate prefecture that has forced at least 3,000 people to evacuate • While it’s nearly 50 degrees Fahrenheit and sunny today in Chernobyl, Ukraine, exactly 40 years ago yesterday the weather worsened the world’s worst nuclear accident by blowing radiation from the melted-down reactor.
The Trump administration has dismissed every member of the independent board that oversees the National Science Foundation. In what The New York Times described as a “terse email” sent Friday afternoon, members of the 25-member National Science Board were told their position was “terminated, effective immediately.” Willie E. May, a terminated board member and a vice president at Morgan State University, told the newspaper: “I am deeply disappointed, though I cannot say I am entirely surprised. I have watched the systematic dismantling of the scientific advisory infrastructure of this government with growing alarm, and the National Science Board is simply the latest casualty.” The move to seize tighter control over funding for scientific research comes two months after the Environmental Protection Agency repealed the legal finding that underpins all federal climate regulations and days after the Department of Health and Human Services nixed publication of a study about the safety of COVID-19 vaccines.
Meanwhile, a top Republican in Congress has confirmed the limits of President Donald Trump’s bid to cap pay at the Tennessee Valley Authority. The White House’s push to limit compensation at the nation’s largest public power utility to $500,000 only applies to the chief executive, Representative Chuck Fleischmann, Republican from Tennessee, told The Knoxville News Sentinel. The White House sought to fire TVA CEO Don Moul last year, but ultimately backed down.

Beijing has laid out plans for tighter controls over fossil fuel use and greater oversight of heavy emitters in what experts told Carbon Brief was “a signal of China’s ongoing commitment to climate action and bridging policy” between the government’s national and sectoral five-year plans. The policy document, totaling nearly 2,800 words when translated into English, is what’s known as a “guiding opinion,” and “is not strictly binding, it bears the stamp of the two highest bodies in China’s political system, conveying a strong sense of authority,” wrote Anika Patel, the China editor at Carbon Brief, noting that “this is the first high-level document to explicitly link decarbonisation efforts with energy security and industrial development.” As Qi Qin, a China analyst at the Centre for Research on Energy and Clean Air, told Heatmap’s Katie Brigham last month: “I don’t think China is creating these technologies as a niche climate experiment anymore. They’re being folded into a broader industrial strategy. I think that the more important question is which of them are moving into real deployment now, and which are still at the stage of strategic signaling.”
At roughly the same time, the Chinese government has published an atlas of deep-sea mineral deposits as the People’s Republic looks to ramp up its ambitions to harvest critical metals from the ocean floor.
At the start of this month, I told you Maine was poised to become the first state to ban construction of data centers, at least temporarily. Not anymore. On Friday, Governor Janet Mills vetoed the bill, the Portland Press-Herald reported. In her message to the legislature, the Democrat said that, while a moratorium “is appropriate given the impacts of massive data centers in other states on the environment and on electricity rates,” the “final version of this bil fails to allow for a specific project in the Town of Jay that enjoys strong local support from its host community and region.” The 2023 closure of Androscoggin Mill, a pulp and paper plant, dealt what she called “a devastating blow” to the town, located roughly an hour and 20 minutes north of Portland, and the server farm would help “promote reinvestment and job creation at the former mill,” she said. Mills is locked in a heated race with left-wing populist Graham Platner for the Democratic nomination to take on Republican Senator Susan Collins this November.

The British-listed green fertilizer company Atome is set to build a first-of-a-kind project in Paraguay, taking advantage of low-cost hydropower to produce ammonia using green hydrogen instead of natural gas. The firm’s final investment decision on the $665 million plant in Villeta, south of the capital of Asunción, comes as the Iran War disrupts fertilizer markets and drives up costs. “We’ve proven that you can actually close and finance an industrial-scale, green fertilizer facility,” chief executive Olivier Mussat told the Financial Times. “It’s never been done before.”
Duke Energy’s Robinson nuclear power plant in South Carolina just won the Nuclear Regulatory Commission’s approval to operate for 80 years as part of the fastest license renewal review in the agency’s history. The NRC cleared Unit 2 of the Robinson Steam Electric Plant — a single-unit pressurized water reactor — to operate for another 20 years. This, according to World Nuclear News, is the unit’s “second, or subsequent, license renewal: it received a 20-year renewal of its original 40-year license in 2004.” The NRC formally accepted the license renewal application for docketing on April 28, 2025, then completed the review within a 12-month timeframe. That’s six fewer months than the previous schedule, in accordance with an executive order Trump issued last year. “This milestone proves we can deliver results quickly without compromising safety,” NRC Chairman Ho Nieh said in a statement. “By focusing on essential factors for sustained nuclear power plant safety and applying lessons learned from past renewals, our team was able to work efficiently while maintaining their commitment to enabling timely safety decisions.”
TotalEnergies may be exiting offshore wind in the U.S. for the price of $1 billion from the Trump administration. But over in Kazakhstan, the French energy giant is expanding its wind footprint. While the landlocked Central Asian country doesn’t have much in the way of shores off of which to build turbines, it does have vast, windy steppelands. TotalEnergies plans to invest in a gigawatt of wind power and 600 megawatt-hours of battery storage, Renewables Now reported.
