The end of consumer electric vehicle tax credits isn’t great, but clawing back federal funding has been even worse.
Trump’s One Big Beautiful Bill took a huge bite out of the climate economy. One segment that emerged largely unscathed, however, is advanced climate tech. Companies working on nuclear, geothermal, battery storage, biofuels, and carbon capture may be shaken by the volatile business environment and a tad worried about provisions such as foreign entities of concern rules that could make their supply chains more complicated. But as of now, they can pretty much proceed with business as usual.
There is one big exception to that, however: The growing ecosystem of electric vehicle charging startups. Not only did OBBBA take a hammer to consumer EV tax credits, Trump also paused funding for key federal charging initiatives on his first day in office. While the startups I talked to were notably blasé about the former situation, executives are seriously worried about how attempts to clawback funding for charging infrastructure will impact the industry as a whole.
The outlook isn’t entirely bleak. Highway fast charging — generally the domain of larger companies such as Tesla, Electrify America, and ChargePoint — has actually seen solid growth so far this year despite the obstacles. But figuring out how to make charging work in urban centers and outlying communities has been a hot market for venture-backed companies over the past few years. And now some of them are facing a moment of reckoning.
“Cities are still pushing forward, but I would say there is a capital-C caution that’s being applied,” Tiya Gordon, founder of the curbside EV charging company It’s Electric, told me. “I think they feel that they need to get it right, and this is true for us as well as a startup. There’s not a margin for error in this environment.”
It’s Electric’s core innovation is siphoning off spare electrical capacity from buildings in cities to run its curbside Level 2, a.k.a. non-fast-charging EV charging network, negating the need for what can be a lengthy and complex grid interconnection process. The company then shares a portion of its revenue with the building owners who agree to the arrangement.
Just days before Trump took office, the startup was awarded $2.2 million from the Department of Transportation’s Charging and Fueling Infrastructure program to deploy curbside charging in Washington, D.C., legally obligated money that the new administration is now trying to rescind. That award remains in legal limbo. “We are proceeding as if we can’t count on that,” Gordon told me. “It’s sand through your fingers in an hourglass.”
That funding came on top of the company’s numerous awards from the Joint Office of Energy and Transportation, an interagency collaboration between the Department of Energy and the Department of Transportation created under the Bipartisan Infrastructure Law. Now the Joint Office has been effectively dismantled as former employees took deferred resignations and Trump has tried to revoke the funding awarded to It’s Electric and other startups.
All of this threatens to shut down a significant source of capital for It’s Electric, as Gordon told me nondilutive funding — largely from federal and state grants — represents nearly half of the company’s total capital raised to date.
Gordon said she sees states stepping into the breach, as climate leaders such as California and New York have thus far stood by their EV expansion plans. But Gordon has already noticed cities employing more diligence than ever when it comes to selecting partners. “They’re really going deep, they’re really taking time, they’re not rushing into any awards. So time is a big factor that represents caution,” she told me. And when it comes to the amount of chargers that cities seem to be looking to build, “the numbers are a little bit more modest.”
She mainly credits this pullback to the whiplash that Trump’s attempt to rescind funding for EV charging has caused. Compared to that, whatever deceleration the end of EV tax credits will cause in consumer uptake is a secondary concern.
“Honestly, that doesn’t really impact us at all,” Jeffrey Prosserman, CEO at Voltpost told me of the tax credits. His company retrofits lampposts in cities and suburbs, turning them into Level 2 EV charging platforms. “At the end of the day, EV adoption will either increase X or Y percent in a given year, but it’s going to continue to increase year over year. We’re past the tipping point, going from early adopters into the mainstream,” he told me.
EV prices are still falling, large businesses still want to electrify their fleets, and self-driving cars — which are far better suited to electric drivetrains — are still getting people excited, all of which should continue to fuel demand for a charging buildout. So while Prosserman acknowledged that nixing the consumer tax credits could “slow adoption by a couple percentage points,” he’s optimistic that the next political cycle will see a resurgence in support.
Like Gordon, however, he is quite concerned about the holdup in funding for both the Charging and Fueling Infrastructure program, or CFI, and its sister initiative, the National Electric Vehicle Infrastructure program, or NEVI. “It creates challenges for the EV charging companies like Voltpost, but it really fundamentally creates challenges for the cities and the general public who expected to have access to charging through these programs,” he told me. “That’s not to say that there isn’t a path forward. It’s just that the path that effectively the entire sector was operating on for the last few years has been reconfigured.”
NEVI is a $5 billion program that aims to build out a national charging network along highways, while CFI allocates $2.5 billion to deploy charging infrastructure in cities, towns, and hard-to-reach areas. Both were stood up in 2021 by the Bipartisan Infrastructure Law.
Politicians, industry analysts, and transportation officials alike have heavily critiqued these programs over the years for appearing to lack urgency, as building a network from scratch has proven to be an enormously complex and cumbersome undertaking. The former executive director of the joint office, Gabe Klein, said at a conference last year that the NEVI program wouldn’t really hit its stride until sometime between 2026 and 2028. Then Trump entered the White House and paused funding for both initiatives, creating a major roadblock for “the entire U.S. EV sector,” Prosserman told me.
Much like It’s Electric, Voltpost started the year by winning its own CFI funding to deploy its chargers in the broader Washington, D.C. region and also secured a number of awards through the Joint Office of Energy and Transportation. With all of that money now tied up in lawsuits challenging Trump’s attempts to freeze the programs, Voltpost’s plans for growth have slowed. “We’re taking a more conservative approach for this year,” Prosserman told me, saying that while the company will eventually seek to raise a Series A it’s “not actively raising that Series A right now, given the macro situation.”
Prosserman said he’s been disappointed to see the general pullback in climate tech venture funding in the first half of 2025. “You have a group of investors who frankly said they are mission aligned, but are now taking a pause, not a stop, given the macroeconomic conditions, and having to wait until the dust settles to see how to reconfigure their portfolios,” Prosserman said. For now, he told me that Voltpost is leaning into its private-sector partnerships such as those with AT&T and Zipcar.
Not all charging companies have experienced this whiplash of funding awards and rescissions, though. SparkCharge, which makes portable, battery-powered fast chargers for commercial fleets and businesses, hasn’t received any NEVI or CFI grant money. The startup primarily serves customers by dispatching off-grid chargers on-demand or setting up stand-alone deployments, which are not core focus areas of either program.
The startup’s Chief Financial Officer David Piperno told me he’s glad that SparkCharge hasn’t relied on such capital, as it’s managed to “become a profitable enterprise with zero incentives, no state funding, no government funding.” That, he said, has allowed the company “to take a different approach to EV charging and be more innovative and have a variable pay-as-you-go model.” So far that seems to be working out pretty well, as it announced $30.5 million in new funding in May through a combination of equity financing and a venture loan.
Reaching former President Joe Biden’s goal of installing 500,000 publicly accessible EV chargers by 2030 still might be a longshot, though, especially as long as the Trump administration continues to target all things EV-related. And yet, charging executives remain relatively upbeat about the sector’s long-term fortunes.
“If you drive one of these vehicles, compared to what you had before, it’s just a superior car, right?” Piperno said, arguing that should continue to power steady consumer growth, even if it doesn’t happen as quickly as experts once predicted. While growth in EV sales increased by 40% in 2023, that slowed to just about 10% last year, as concerns over the availability of charging infrastructure, price, and range persist. “I think everyone thought that [the EV adoption] curve was going to be a lot faster. But I think that’s really normalized over the past few years already, and we don’t, quite frankly, see it normalizing much more than it has.”
At least now, executives told me, there’s more certainty regarding the policy landscape than at the beginning of the year. That holds especially true for startups that are willing and able to operate under the assumption that they might never see much of their recently awarded federal funding — at least anytime soon.
“The expression was, wait and see, wait and see, wait and see,” Gordon told me of Trump’s first months in office and the uncertainty around EV incentives and funding programs. “And now we waited and we saw, and it’s gone. And so we mourn and we move on, right?”

Tom Ferguson, founder of Burnt Island Ventures, has bigger concerns.
Water — whether too much or too little — is one of the most visceral ways communities experience the impacts of a warming world. It’s also a $1.6 trillion global market that underpins much of the world’s economy. As climate-related risks such as droughts, floods, and contamination converge with systemic challenges like aging water infrastructure and clunky resource management, the need for innovation is becoming painfully obvious.
As Heatmap’s own polling shows, water is also becoming an increasingly large part of the data center story, with many Americans opposing these facilities in part due to concerns over their water usage. That anxiety may not be entirely rational, Tom Ferguson, founder of the water-focused investment firm Burnt Island Ventures, told me.
He’s spent the better part of his career funding water-related innovation, focusing on where new technologies stand to have the greatest impact. So I believed him when he said that while data centers don’t merit quite so much worry, water as a resource deserves a far greater role in the climate tech conversation.
“Everybody assumes that water is a dog of a market because nobody really speaks water. It’s not within their circle of competence,” Ferguson told me, explaining that many firms simply don’t have employees with industry expertise. “But it’s awfully helpful to work with people who can give you a reasonably sized check — ideally two reasonably sized checks, maybe even more — and then also be helpful on that journey to help you better diagnose reality.”
That’s the goal of Burnt Island, which just closed a $50 million fund — its second overall — dedicated to backing early-stage water innovators. Ferguson’s team may have announced the close today, but the firm has already deployed the majority of the fund’s capital into companies working on everything from advanced water treatment and filtration to infrastructure resilience and climate adaptation. At the same time, Burnt Island is also raising money for a $75 million growth fund, designed to invest in later-stage startups with more proven tech.
Ferguson is a veteran of the industry, having previously run an innovation accelerator at the water nonprofit Imagine H2O, which vets hundreds of water startups every year. He’s also solution-agnostic — Burnt Island has already backed a startup developing an underwater desalination plant, a “defrosting innovation company” pioneering a water-efficient way to thaw frozen food, and an effort to build an algae-based wastewater treatment system.
One area Ferguson is not interested in backing, however, is data center cooling systems. Most large data centers cool servers by circulating water through heat exchangers that absorb heat from the equipment. The hot water is then sent to cooling towers where a portion is evaporated. This releases heat into the air, allowing the cooled water to be recirculated. More novel and efficient — but much less proven — cooling methods include applying coolant directly to the chips themselves or submerging entire servers in a non-conductive liquid.
Those approaches are simply too risky, Ferguson told me — both for him and for the hyperscalers. Cooling, he explained, represents a relatively small fraction of a data center’s project cost, but the cost of failure is enormous. If a novel cooling system goes awry, valuable computer chips will fry and operations will grind to a halt. “Under those circumstances, why would you take that chance?” he asked. “You want to use something that has already been proven, that is totally reliable.”
Ferguson told me he’s happy to let firms with larger pocketbooks bet their money on these solutions, but he’s also assuming that hyperscalers will wind up building a lot of these systems themselves. “They’re going to develop their own stuff in house because they want to have the end-to-end control over the architecture,” he told me. “All of this adds up to a pretty tough market.”
That doesn’t mean he’s bearish on data center water efficiency in general. Many of his portfolio companies see opportunities to, say, use metering and sensing tech to track data center water use, or treat water coming into and out of the facilities. And he’s well aware of the public’s growing scrutiny of the industry’s water intensity, having followed the $3.6 billion data center project in Tucson, Arizona that was cancelled in August amidst community-led drinking water concerns.
But he thinks kerfuffles such as this are often more about perception than reality. “The water impact is slightly overblown,” he told me. Data centers “still use a lot less water than golf courses.” And while the rapid expansion of artificial intelligence infrastructure will inevitably put data centers ahead of golf courses one day, Ferguson trusts that this cash-rich industry will be able to reduce water intensity on its own, as developers have a direct incentive to expand in as many geographies as possible.
Even the canceled Arizona project, he told me, had a reliable plan to replenish the local watershed. Microsoft, Amazon, and Google have all pledged to be “water positive” by 2030, returning more water to data center communities than their facilities use by making their operations more efficient while also restoring local ecosystems and replenishing watersheds. But now that the water use narrative has gained steam, “it actually doesn’t matter what you do physically. It’s what people believe about the resource hungriness of these things,” Ferguson explained.
The more important question, he believes, is whether AI’s overall impact on the world will end up justifying the water it consumes. And as he told me, “the jury is really out” on that for now.
But when it comes to weighing water consumption against the pure economic value of data centers, Christopher Gasson, owner and publisher of the market intelligence firm Global Water Intelligence, has actual numbers.
As Gasson asserted in a presentation that Ferguson attended, in terms of the amount of fresh water used per dollar of revenue generated, data centers perform quite well compared to the world’s other leading industries. Their so-called “revenue intensity” is far lower than that of the semiconductor, power generation, food and beverage, and chemicals sectors, for example.
So for Ferguson, the AI-water intersection that feels most relevant is actually “vertical AI” — models trained specifically on water industry data to address targeted problems in the sector. Training these smaller, specialized models is not only far less resource-intensive, it also allows for much more accurate results than general purpose models, which often hallucinate when trying to address niche queries and concerns.
One of Burnt Island’s portfolio companies, SewerAI, trains its model on reams of sewer inspection data. Using video footage, the software can then perform automated sewer inspections to identify defects in pipes, eliminating the timely, costly, and often inaccurate process of manual video review. Another portfolio company, Daupler, uses its specialized model to automate how water utilities respond to service incidents, categorizing and prioritizing customer reports, dispatching crews, and tracking progress. Burnt Island led Daupler’s Series A round and has already supported it with additional capital through its growth fund.
“You have these really, really high quality, very compelling business models that are being built relatively quietly,” Ferguson said. But he expects these opportunities to gain more attention soon — because while the headlines and community uproar around the water intensity of AI may sometimes be hyperbolic, the necessity of water to human life is anything but.
“You can’t believe in water in the same way that people have chosen to believe in the impact of emissions,” Ferguson told me. “You don’t get to choose when it comes to water issues, because once they get real, they get really real.”
On Japan’s atomic ‘Iron Lady,’ Electra’s supercharge, and a mineral deal Down Under

US Wind told a federal court that it will go bankrupt if President Donald Trump succeeds in revoking its building permits. The Baltimore-based developer testified on the fate of its 2.2-gigawatt Maryland Offshore Wind project in response to a lawsuit brought by the Department of the Interior and the City Council of Ocean City, Maryland. “If the plan is lost, surrendered, forfeited, revoked or otherwise not maintained in full force and effect, US Wind’s investors have the right to declare US Wind to be in default on the repayment of the company’s debt and/or refuse to extend the additional financing needed to complete construction of the project,” the company told the court, according to an update on the energy consultancy TGS’ 4C Offshore news website. “Either of these consequences could result in US Wind’s bankruptcy.”
The Trump administration’s “total war on wind,” as Heatmap’s Jael Holzman described the multi-agency onslaught against offshore projects, has drawn a backlash in recent months. As I reported last month in this newsletter, a federal judge temporarily stayed Trump’s stop-work order on a 80% complete wind farm off Rhode Island’s coast. Even the oil industry has come out to support the wind sector, as I wrote earlier this month, with Shell’s top U.S. executive warning that the precedent the administration had set would harm fossil fuel producers once Democrats return to power. Yet the effects of the administration’s policies are starting to pinch.
Electra announced a series of major deals on Tuesday as the green iron startup unveiled its debut demonstration facility in Boulder, Colorado. Just a month after Microsoft agreed to buy green steel for its data centers from Sweden’s green steelmaker Stegra, Facebook owner Meta agreed to buy environmental attribute credits linked to emissions cut from Electra’s clean iron. The startup also announced three major offtake agreements — the steelmaker Nucor, the European metal trader Edelstahl Group, and Japanese steel-trading giant Toyota Tsusho all signed deals for Electra’s iron. Meanwhile, Electra brought on new financing. Bill Gates’ Breakthrough Energy invested $50 million in grants into the company, while Colorado Governor Jared Polis provided the five-year-old startups with an $8 million tax credit from the state’s clean industrial financing program. And all that is just what the company announced Tuesday. Earlier this year, as Heatmap’s Katie Brigham reported, Electra closed a $186 million Series B round.

The top U.S. solar trade group, the Solar Energy Industries Association, is looking for a new leader. After eight years in office, Abigail Ross Hopper, the lobby organization’s chief executive, announced her departure Tuesday amid what she called a “challenging” year for the industry in her public exit letter. When she took office in 2017, the solar industry had a total capacity of 36 gigawatts and just over 1 million residential customers. By today, the industry has grown to more than 255 gigawatts and more than 5.5 million residential customers. Despite struggles competing against China, U.S. solar manufacturing capacity vaulted from 14th globally to the world’s third-largest hub of photovoltaic factories. “The growth we’ve experienced over the years is a result of our collective grit and determination,” she wrote in the letter. “We’ve navigated fierce policy battles and market challenges, from trade cases to tax debates, and yet we’ve always emerged stronger. We fought — and won — historic policy battles, at every level of government.” While the Trump administration’s cuts to solar programs have dulled growth forecasts, she said she was “optimistic” about the future. Her last day will be January 30, 2026.

After months of negotiations, the U.S. and Australia signed onto a two-way trade deal on critical minerals worth $8.5 billion. The move comes as China ratchets up export controls on rare earths and other metals over which Beijing dominates global supplies. Australia and Canada, whose economies heavily depend on mining, are widely considered the most dependable sources of minerals for the U.S., a dynamic highlighted last week by the cancellation of an American metal project by the leaders of a coup in Madagascar, as I reported for Heatmap. For Australia, the agreement “is a really significant deal,” Hayley Channer, the director of the economic security program at the United States Studies Centre at the University of Sydney, told The Guardian. “I’m surprised how good it is. The fact that any U.S. money is coming to Australian companies is huge; we really need this money. I don’t think it could have gone any better.”
Japan just elected its first female prime minister, the arch-conservative former minister of economic security Sanae Takaichi. Like Margaret Thatcher, the first woman to serve as British prime minister, Takaichi has been dubbed the Iron Lady due to her hard-line nationalistic views. But uranium may be a better metal for the nickname. Like Thatcher, Takaichi has vowed to restore Japan’s nuclear industry to its former might. Less than half of Japan’s 33 operable nuclear reactors are currently online and generating electricity, a legacy of the mass shutdown that followed the 2011 Fukushima-Daiichi plant. In lieu of atomic energy, Japan — which lacks the land for vast wind and solar installations — has turned instead to costly liquified natural gas imports. To Takaichi, who wants to remilitarize Japan and take a more aggressive stance toward China, this creates a vulnerability. Without domestic gas fields, Japan relies on imports whose routes the Chinese navy could disrupt in a conflict, weaponizing blackouts in much the same way Russia has in Ukraine. Japan’s offshore wind efforts are badly delayed. And Takaichi has warned that Beijing’s grip over global manufacturing of photovoltaic panels makes solar a threat, as well.
Japan isn’t the only country looking to revive its past atomic ambitions. South Africa’s government approved the state-owned utility Eskom’s integrated resource plan last week, which included starting work again on the company’s abandoned pebble-bed modular reactor program. First proposed in 1999, the technology is billed as safer than light water reactors and more versatile, with the potential for use in more heavy industry settings. But South Africa canceled the program in 2010 after spending $980 million developing the reactor. The country currently depends on coal for nearly 60% of its electricity.
Scientists discovered an ancient climate archive in a remote cave in northern Greenland. In a study published in Nature Geoscience, the researchers found calcite deposits that only form when the ground is unfrozen and water flows. The findings cast new light on past warm periods in the Earth’s climate, particularly the Late Miocene, which began about 11 million years ago. “These deposits are like tiny time capsules,” Gina Moseley, a geologist with the University of Innsbruck in Austria and an author of the study, said in a press release. “They show that northern Greenland was once free of permafrost and much wetter than it is today.”
Rob and Jesse hang with Dig Energy co-founder and CEO Dulcie Madden.
Simply operating America’s buildings uses more than a third of the country’s energy. A major chunk of that is temperature control — keeping the indoors cool in the summer and warm in the winter. Heating eats into families’ budgets and burns a tremendous amount of fuel oil and natural gas. But what if we could heat and cool buildings more efficiently, cleanly, and cheaply?
On this week’s episode of Shift Key, Rob and Jesse talk to Dulcie Madden, the founder and CEO of Dig Energy, a New Hampshire-based startup that is trying to lower the cost of digging geothermal wells scaled to serve a single structure. Dig makes small rigs that can drill boreholes for ground source heat pumps — a technology that uses the bedrock’s ambient temperature to heat and cool homes and businesses while requiring unbelievably low amounts of energy. Once groundsource wells get built, they consume far less energy than gas furnaces, air conditioners, or even air-dependent heat pumps.
Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap, and Jesse Jenkins, a professor of energy systems engineering at Princeton University. Jesse is an adviser to Dig Energy.

Here is an excerpt from our conversation:
Jesse Jenkins: We’ve been throwing a few different terms around here to describe this. We talked about geothermal heating and cooling, ground source heat pumps, geoexchange. There’s a little bit of ambiguity here in the language people used to talk about these things. What’s your favorite way to talk about this product and why?
Dulcie Madden: Ugh.
Jenkins: Or is this just an endless debate that is not resolved?
Madden: It is a great question. It’s a big debate. When I think of geoexchange, just so everyone knows, it’s really about, like, are you able to basically create a larger array, potentially, across buildings, more like exchanging heating and cooling, like both point source and — I think about it more in the context of Princeton, where it’s also across buildings, right? And that starts to move into what some people call a thermal energy network. And so there’s some work there.
There is a lot of back and forth between geothermal heat pump and ground source heat pump, and a lot of people will use them interchangeably. I think that there is technically a differentiation, but I don’t know if there’s a didactic, like, This is what it is. It’s just … you have to be interchangeable.
Jenkins: Yeah, I’m curious, I don’t know what the best marketing term is, what people actually resonate with beyond the technical crowd. I was describing what you guys were doing when you closed your seed series round on X or BlueSky, and somebody jumped into the replies. That’s not geothermal energy, it’s ground source heat pump. And it’s like, okay. And I guess the argument is that, because it’s basically just using it as a source for heat exchange in the heat pump operation as opposed to extracting heating out of the ground — which you can do. I mean, you can just do direct heating from geothermal.
Madden: Right.
Jenkins: Deep geothermal drilling, as well. It’s something that Eavor, which is an Alberta-based deep geothermal company that I advise, as well, is working on their first commercial project in Bavaria. That’s gonna go into a district heating system. So they’re going produce a little bit of power, but a lot of that is just direct heat. But again, they’re drilling, five, six kilometers deep and pulling out heat at high temperatures. And so it’s because it’s kind of back and forth, you’re using this kind of buffer for both heating and cooling. I think that’s why people might push back on the idea that it’s geothermal. But you’re using the heat in the ground.
