Revoy is already hitching its power packs to semis in one of America’s busiest shipping corridors.

Battery swaps used to be the future. To solve the unsolvable problem of long recharging times for electric vehicles, some innovators at the dawn of this EV age imagined roadside stops where drivers would trade their depleted battery for a fully charged one in a matter of minutes, then be on their merry way.
That vision didn’t work out for passenger EVs — the industry chose DC fast charging instead. If the startup Revoy has its way, however, this kind of idea might be exactly the thing that helps the trucking industry surmount its huge hurdles to using electric power.
Revoy’s creation is, essentially, a bonus battery pack on wheels that turns an ordinary semi into an EV for as long as the battery lasts. The rolling module carries a 525 kilowatt-hour lithium iron phosphate battery pack attaches to the back of the truck; then, the trailer full of cargo attaches to the module. The pack offers a typical truck 250 miles of electric driving. Founder Ian Rust told me that’s just enough energy to reach the next Revoy station, where the trucker could swap their depleted module for a fresh one. And if the battery hits zero charge, that's no problem because the truck reverts to its diesel engine. It’s a little like a plug-in hybrid vehicle, if the PHEV towed its battery pack like an Airstream and could drop it off at will.
“If you run out of battery with us, there's basically no range anxiety,” Rust said. “And we do it intentionally on our routes, run it down to as close to zero as possible before we hit the next Revoy swapping station. That way you can get the maximum value of the battery without having to worry about range.”
To start, a trucker in a normal, everyday semi pulls up to a Revoy station and drops their trailer. A worker attaches a fully charged Revoy unit to the truck and trailer—all in five minutes or less, Revoy promises. Once in place, the unit interfaces seamlessly with the truck’s drivetrain and controls.
“It basically takes over as the cruise control on the vehicle,” he said. “So the driver gets it up to speed, takes their foot off the gas, and then we actually become the primary powertrain on the vehicle. You really only have to burn diesel for the little bit that is getting onto the highway and then getting off the highway, and you get really extreme MPGs with that.”
The Revoy model is going through its real-world paces as we speak. Rust’s startup has partnered with Ryder trucking, whose drivers are powering their semis with Revoy EVs at battery-swap stops along a stretch of Interstate 30 in Texas and Arkansas, a major highway for auto parts and other supplies coming from Mexico. Rust hopes the next Revoy corridor will go into Washington State, where the ample hydropower could help supply clean energy to all those swappable batteries. Happily, he said, Revoy can expand piecemeal like this because its approach negates the chicken-and-egg problem of needing a whole nation of EV chargers to make the vehicles themselves viable. Once a truck leaves a Revoy corridor, it’s just a diesel-powered truck again.
Early data from the Ryder pilot shows that the EV unit slashed how much diesel fuel a truck needs to make it down the designated corridor. “This is a way we can reduce a path to reduce the emissions of our fleet without having to buy anything — and without having to have to worry about how much utilization we're going to have to get,” Mike Plasencia, group director of New Product Strategy at Ryder, told me.
Trucking represents one of the biggest opportunities for cutting the carbon emissions of the transportation sector. It’s also one of the most challenging. Heatmap has covered the problem of oversized SUV and pickup truck EVs, which need larger, more expensive batteries to propel them. The trucking problem is that issue on steroids: A semi can tow up to 80,000 pounds down an American highway.
There are companies building true EV semi trucks despite this tall order — Tesla’s has been road-testing one while hauling Pepsi around, and trucking mainstays like Peterbilt are trying their hand as well. Although the EV model that works for everyday cars — a built-in battery that requires recharging after a couple hundred miles — can work for short-haul trucks that move freight around a city, it is a difficult fit for long-haul trucking where a driver must cover vast distances on a strict timetable. That’s exactly where Revoy is trying to break in.
"We are really focused on long haul,” he told me. “The reason for that is, it's the bigger market. One of the big misconceptions in trucking is that it's dominated by short haul. It's very much the opposite. And it's the bigger emission source, it's the bigger fuel user."
Rust has a background in robotics and devised the Revoy system as a potential solution to both the high cost of EV semis and to the huge chunks of time lost to fueling during long-distance driving. Another part of the pitch is that the Revoy unit is more than a battery. By employing the regenerative braking common in EVs, the Revoy provides a redundancy beyond air brakes for slowing a big semi—that way, if the air brakes fail, a trucker has a better option than the runaway truck lane. The setup also provides power and active steering to the Revoy’s axle, which Rust told me makes the big rig easier to maneuver.
Plasencia agrees. “The feedback from the drivers has been positive,” he said. “You get feedback messages like, it felt like I was driving a car, or like I wasn't carrying anything.”
As it tries to expand to more trucking corridors across the nation, Revoy may face an uphill battle in trying to sell truckers and trucking companies on an entirely new way to think about electrifying their fleets. But Rust has one ace up his sleeve: With Revoy, they get to keep their trucks — no need to buy new ones.

The bipartisan proposal from the House Science Committee comes with the backing of the Fusion Industry Association.
The nuclear fusion industry has been asking for a $10 billion investment from the U.S. government. Now, there’s a bipartisan coalition in Congress ready to give it to them.
On Thursday, Californians Zoe Lofgren, ranking member of the House Science Committee, and Jay Obernolte, chair of the body’s Subcommittee on Research and Technology, introduced the American Leadership in Fusion Act, which would pump some $10 billion into the industry to commercialize the frontier nuclear energy technology.
The $10 billion number was not pulled out of a hat (or a stellarator). The Fusion Industry Association called for a “one-time $10 billion injection of U.S. public capital into efforts and partnerships with the private fusion industry” late last year, a figure the group said was based on analyses from the National Academies of Science and a Department of Energy advisory committee.
“Fusion is the future, and this bipartisan bill is a major step in capitalizing on the promise of its emission-free power,” Lofgren said in a statement. “This bill will unleash a new era of fusion energy development in the United States.”
At our Heatmap House event at New York Climate Week on Wednesday, Commonwealth Fusion Systems CEO Bob Mumgaard acknowledged that $10 billion is a lot of money, but “you have to say what gets the job done. It’s a disservice to lowball what is needed. It’s this very important thing — it’s an entire new industry. Let’s treat it as such.”
The fusion industry hasn’t necessarily been hurting for private capital. In July, the FIA reported that 56 companies had raised almost $4.5 billion in the past year. CFS alone announced $1 billion of new funding in July, bringing its total investment up to $4 billion. Of the over $14 billion the industry has raised, almost a third has gone to CFS.
Whether this federal funding ever materializes remains to be seen. A Department of Energy official poured cold water on the $10 billion figure in July, telling the industry that the figure wasn’t plausible, according to Politico.
Obernolte and Lofgren’s bill would split the $10 billion into several pots all aimed at commercializing fusion technology, which has been the subject of university and scientific consortium research for decades.
The biggest chunk, almost $4 billion, would be devoted to building test facilities to work on materials and fuel. Another $2 billion would be put into the existing “milestone-based development program,” established by 2020’s Energy Act and expanded in the 2022 CHIPS and Science Act, which links funding to preset scientific and business targets. CFS has won funding through this program, as have seven other companies including Thea Energy and Tokamak Energy. Another $3 billion in the bill would go to a new demonstration program, analogous to the existing Advanced Reactor Demonstration Program for fission projects, which would probably involve fewer awards for bigger projects that require substantial cost sharing.
While it’s unlikely that this bill could become law this Congress, considering that the House of Representatives has left town to campaign for the midterms, fusion legislation typically garners bipartisan support. The ADVANCE Act, which included regulatory language easing fusion’s regulatory pathway, was signed into law in 2024 after passing the Senate in an 88-2 vote. It is unlikely, Democratic committee staff acknowledged, that the bill get a vote this Congress, but it could start momentum towards a bipartisan fusion bill in a future Congress.
Science Committee staff have been working on the American Leadership in Fusion Act since earlier this year, soliciting advice from national labs, universities, and companies working on fusion technology. The bill has won the endorsement of fusion industry heavyweights like CFS, the Fusion Industry Association, and several energy policy nonprofits and universities, including the Clean Air Task Force and ClearPath Action.
And it’s not crazy to expect the administration to take an interest in the bill, either, considering the latter’s bipartisan backing and alignment with the former’s own stated goals, a senior Democratic committee staffer told me.
Earlier this year, the Department of Energy released a Fusion Science and Technology Roadmap, which “aims to usher a burgeoning U.S. fusion industry toward maturity on the most rapid, credible timeline” including through “leveraging public and private sector investments.”
Third Way’s head of climate and energy argues that both sides have lost voters’ trust, with serious consequences for our infrastructure.
In September 2024, then-presidential candidate Donald Trump told a crowd in Wilmington: “We will cut your energy prices in half … Mark it down, and you can get very angry at me if we don't do it.” He gave himself one year from when he’d take office.
Two years later, rates are up. And we’re angry.
Utilities requested $18.6 billion in rate increases in the first half of 2026, including a record $9.2 billion in the second quarter alone. Gas prices are hovering close to $4.50 a gallon, almost a full dollar more than this time last year. Diesel prices are even worse, recently passing $6.50 a gallon, up by over 50% from one year ago.
In the past two years, electricity prices have increased by over 10%. In the past five years, it’s over 36%.
President Trump’s failure to lower costs has tanked his approval ratings, currently just 34% overall and 33% on his handling of the economy. But he’s not alone. Incumbent politicians across the country — along with utilities, energy-intensive businesses, and tech companies — have found themselves swept up in the backlash.
Those feelings of blame and distrust have emanated throughout our democracy. Just 27% of Americans trust national institutions, according to a June Gallup poll, a single point above the all-time low. Just 17% trust the federal government to do what's right. Nearly seven in 10 people fear that institutional leaders are deliberately misleading them.
Looking at our energy infrastructure, I understand the feeling. Government and industry have chronically neglected our electricity delivery system, offering impossible-to-fulfill slogans rather than real solutions.
Over the past four years, this has created what I’m calling the Energy Trust Gap. It results from the toxic collision of an aging, neglected, and overstressed grid; rising prices; and voter frustration with policymakers, regulators, and industries that overpromise and underdeliver.
This is not merely a Trump problem, though it is true that the president’s chaotic tariff strategy, his impossibly stupid war in Iran, and his senseless energy obstruction have dramatically widened this rift.
Instead of deploying more energy to the grid, the Trump administration has blocked renewables when Americans need them most. It paid TotalEnergies $928 million and Invenergy $765 million to abandon offshore wind leases — $1.7 billion of public money not to build power. Through the Pentagon, it has halted over 28 gigawatts of onshore wind projects in 21 states, and attempted to suspend five fully permitted projects already under construction. Thankfully, all five won injunctions and resumed development by February. Still, the industry's trade association estimated that the cancellations and delays would add $45 billion in East Coast energy costs over a decade.
Though a federal appeals court recently ruled against it, the administration was also using emergency authority to keep 11 fossil units at seven plants running at a cost of roughly $1.5 million per day. The evidence is quite weak that these units are necessary to maintain grid stability or meet unexpected demand. Some are producing substantially less power than they can, or have even been taken offline.
But the Energy Trust Gap has not been created by Republicans alone. Here is the part my side needs to sit with.
In 2022, then-President Biden promised that the Inflation Reduction Act would “bring down family energy bills by an average of $500 a year.” The White House projected that, alongside the 2021 Bipartisan Infrastructure Law, the IRA would cut electricity rates by up to 9% by 2030. Advocates promised the law would create “more than 9 million good jobs.”
The Trump administration undid some of the efforts to fulfill these promises before they could bear fruit. But others were flimsy from the start.
An accompanying report on the 9 million jobs figure acknowledged, in a footnote, that “not all of the jobs created will be net new employment,” but rather would constitute workers hired away from elsewhere to remedy a tight labor market. It also clarified that “job” was less accurate than “job-year equivalent,” a technical measure of labor volume rather than individual people holding durable positions.
These caveats never made it into the president’s public comments, including at events I helped host.
We expected the government to spur private sector demand and create jobs across the country. We assumed the public would see the benefits and credit our clean energy policies. But voters didn’t see an IRA-driven jobs boom in their communities, didn’t feel its impact in reducing costs amid a crisis, and didn’t see it improving their lives.
Yes, there were jobs. But in an economy as large as the United States, the public simply doesn’t distinguish “clean energy jobs” from other sectors.
The promise of a national electric charging network to enable EV ownership didn’t pan out, either. Congress made $4.4 billion available for chargers in 2022; four years later, states had opened only around 150 public charging stations, a flop for a program designed to fund about 1,600 stations on the path to phasing out gas vehicles. Same story with home heating. The American Council for an Energy-Efficient Economy found that in all four high-electricity-price states it modeled, the average gas household's bills increased after electrification.
When heating homes already accounts for more than 40% of residential energy consumption, you cannot credibly advocate for more expensive options.
These functional failures were also messaging failures. By 2024, 40% of registered voters hadn’t heard anything about the IRA. Governors got more credit for new renewable energy and green manufacturing facilities than President Biden did, according to a post-mortem on the law led by the University of Michigan’s Alexander Gazmararian. The Biden administration placed a big political bet on actions that were misbranded, inadequately promoted, and ultimately undeliverable before November 2024 — the only timeframe that mattered.
Let me be clear: The Energy Trust Gap will cost Democrats elections.
As policymakers head into November’s midterm elections, they are being called upon to answer for the proliferation of data centers and the skyrocketing cost of electricity. In this moment, Democrats could seize momentum from Republicans. But many are still ignoring the lessons of the past four years.
A large number of voters believe clean energy advocates are exaggerating the affordability of renewable energy. If candidates argue that the transition to clean energy is a guaranteed outcome, and that Biden’s climate law worked, they will lose.
Reality is breaking through in some places: Officials are concerned about the cost-of-living crisis, explicitly acknowledging the trade-offs that come with climate policy and prioritizing affordability for ratepayers above all else. In March, for example, Massachusetts Governor Maura Healey signed an executive order to bring more energy and energy storage to the Bay State, calling for an “all-of-the-above approach to energy, including “solar, wind, gas, nuclear and hydro.” In New York, Governor Kathy Hochul has been honest that the state cannot meet its 2030 climate targets “without imposing new and additional crushing costs,” citing state estimates of more than $4,000 a year for upstate households burning oil and gas.
“Something has to give,” she said.
That honesty is critical. Policymakers, clean energy and climate advocates, and industry cannot fix the issues plaguing our energy system without regaining some credibility.
Here’s where I would start:
This is the uncomfortable but necessary path to closing the Energy Trust Gap. The alternative is more broken promises and putting our ambitions for energy, the economy, national security, and climate completely out of reach.
If policymakers can’t be straightforward about the trade-offs and deliver on their solutions, we’ll doom ourselves to policy whipsawing and another energy crisis.
Then another. Then another. Then another.
Current conditions: Aside from tides up to two feet above average on Staten Island and Long Island, the powerful nor’easter barreling toward the East Coast is likely to spare New York City • Tropical Storm Nolo is set to hit Hawaii with a potentially historic multi-day deluge • Hurricane Polo is slamming into Mexico’s Pacific coast with dangerous swells and heavy rain.
On Tuesday, President Donald Trump told reporters he had “called for” halting exports of diesel as prices roared to record highs amid a shortage of refining capacity to produce the fuel. On Wednesday, Politico reported that the administration was “preparing” a 90-day export ban. When Secretary of Energy Chris Wright took the stage at Heatmap House, our day-long summit on Wednesday in Midtown Manhattan, he told our executive editor Robinson Meyer that — contrary to the previous comments — the president “didn’t endorse” an export ban. “We are open to any ideas to lower energy prices for Americans,” Wright said at our annual event for New York Climate Week, essentially the amuse bouche before the United Nations climate summit in November. “We have a continual, thoughtful dialog based on the facts on the ground of what are the most practical steps moving forward, and it looks like right now we do need to grow the diesel supply in the United States.”
Former Vice President Al Gore, meanwhile, injected some optimism into the discussion about decarbonization. Reflecting on how climate discourse had evolved since the release of his famous film An Inconvenient Truth 20 years ago, he said booming electric vehicle sales and a global shift to renewables and nuclear power spurred by the energy shock from the war in Iran showed that “these are signs that this thing is really moving into high gear.” He added: “The fossil fuel industry is losing. They know they’re losing, and they’re trying to slow down how quickly they lose.” Yet perhaps one of the best hopes for speeding up deployment of more clean energy dimmed last night when Punchbowl News reported that increasingly bullish talks on permitting reform may be tanking. “The administration and congressional Republicans agreed to a strong bipartisan offer. The Democrats have since refused to take yes for an answer. If they think that the administration is going to freeze these concessions until the lame duck, they are severely mistaken,” a White House official told the outlet.

Later in the afternoon yesterday, I scurried off to the New York Nuclear Symposium, the annual conference organized by the advocacy group Nuclear New York. In the august halls of the New York Bar Association on 44th Street, policy experts and executives debated exactly what was needed to shift the excitement over atomic energy into actual projects with shovels in the ground. While some doubts persisted over how quickly anyone would commit to new fission plants in the U.S., at least beyond the various first-of-a-kind projects currently under development, the American government charged forward with export deals. Earlier this week, the U.S. Trade and Development Agency announced a partnership with Turkey to build as much as 5 gigawatts of small modular reactor power in the country. On Thursday, NucNet reported that Poland’s national nuclear company had reached a deal with the U.S. developers Bechtel and Westinghouse on the commercial terms for the European nation’s first atomic power station, a trio of Westinghouse AP1000s on the Baltic sea.
Meanwhile, the South Korean project manager and builder Samsung C&T unveiled new deals with two SMR companies in the U.S. The company pledged $100 million toward building the next-generation reactors designed by Google-backed Kairos Power. A day later, the company signed onto projects involving GE Vernova Hitachi Nuclear Energy’s 300-megawatt reactor, based on a traditional water-cooled design.
Enhanced geothermal leader Fervo Energy announced Thursday morning that it had shipped the first megawatts to the grid from its flagship Cape Station project, nearly three years to the day after breaking ground at the site. The facility in Beaver County, Utah marks a significant scale-up from the company’s earlier Project Red, located in the Blue Mountain geothermal field of Nevada, which began supplying 3.5 megawatts of electricity to the grid in 2023. Cape Station, by contrast, is the company’s first greenfield project. Phase I of the facility consists of three 33-megawatt units, the first of which has begun ramping up, while the remaining two are expected to reach commercial operations by 2027. “I could not be more proud of the years of hard work from Fervo’s employees, investors, suppliers, customers, and partners, which brought us to this moment,” Fervo CEO Tim Latimer said in a statement. “We are just getting started.”

Last month, my colleague Emily Pontecorvo and I reported on the Department of Commerce’s latest import levies on polysilicon, the main ingredient in most solar panels. The restrictions were designed to keep out cheap, subsidized competition from Chinese companies. But the nearly four-month delay in the policy’s implementation opened the door to companies stockpiling foreign-made reactors. To avoid that, the Commerce Department’s Bureau of Industry and Security has issued a temporary rule explaining how it will monitor imports, Solar Power World reported. Starting December 4, polysilicon components in a panel such as wafers, cells, and the finished rigs themselves will have a 15% tariff.
“Flooding the U.S. market with large volumes of imported products is a strategy that companies abroad have long used to undermine American manufacturers,” Andy Park, the global chief executive officer of Hanwha Qcells, said in a statement. “We have repeatedly seen import volumes surge ahead of the implementation of significant U.S. trade or industrial policies, as companies seek to exploit loopholes and gain an unfair advantage before new measures take effect.”
“When it comes to fuels, we have plenty of options, but nothing has hit the jackpot.” That’s what Ernest Moniz, former President Barack Obama’as energy secretary, told me yesterday morning on stage at a Climate Week breakfast hosted by his nonprofit, the EFI Foundation. Just 21% of the world’s end-use energy comes from electricity, meaning 79% comes from molecules — mostly natural gas and oil. The point Moniz, a Massachusetts Institute of Technology-trained physicist, was making was that we need to take green fuels such as hydrogen and biodiesel more seriously. “My bet for scalability is some or multiple colors of hydrogen,” referring to the rainbow of names that denote how hydrogen fuel is produced. Hours later, Hydrogen Insight reported that the German energy giant Uniper had signed “one of the largest” offtake deals ever for aviation fuel made with green hydrogen. As part of the deal, the Düsseldorf-based firm will buy 40,000 metric tons of green fuels for at least the next decade.
The New York State Research and Development Authority announced awards for eight energy storage facilities and 13 large-scale renewable projects on Wednesday, totaling $3.7 billion in private investment. Combined, the projects are expected to pump out 1.7 gigawatts of power. “These newly-contracted large-scale energy projects not only further the growth of clean energy and more than double the utility-scale energy storage that exists currently statewide — but they contribute to New York’s comprehensive, all of the above energy strategy,” Doreen Harris, NYSERDA’s chief executive, said in a statement. “This will help reduce costs for New York ratepayers while continuing to improve the reliability of our state’s grid.”
