🌎 Who builds Europe’s biggest climate companies #318

Happy Monday!

We're taking a Eurotrip and diving into a new report from AENU, built on Currence data, that traces who actually builds Europe’s best-funded climate companies. We compare them with their US counterparts below.

In deals, $298m for salt-cooled high-temperature nuclear reactors in California; $78m for smart energy systems in Hamburg; and $70m for disaster-exposed property insurance in California.

In other news, the DOJ moves to reopen Revolution Wind’s approval, steep new solar cell tariffs on India and Southeast Asia, and geothermal wins rare bipartisan love.

Old World, new founders

In the US, the climate tech founder stereotype is Tesla mafia or a Stanford MBA. That’s not the case in Europe. Our friends at AENU, a Berlin-based early-stage VC investing in energy transition, industrial transformation, and resilience tech, just released a report using market data from Currence 😉 to see who actually builds Europe’s biggest climate companies, and how they got there.

Check out the really cool interactive version of AENU’s The Execution Game here and download the report there, or read on for more!

The team traced the careers of the founders behind Europe’s 100 best-funded climate companies, each of which had raised at least €50m, then ran the same analysis on 100 US founders for comparison. (You can see all the companies in the report.) They also interviewed ten company leaders, including the founders of Tokamak Energy, Wallbox, and Sunly, and named 20 “Tomorrow’s Champions” to watch. 

European founder highlights

1. Europe has no founder campus, compared to three in the US. Europe’s 100 top founders studied at 118 institutions, and no school produced more than five founders (Cambridge). In the US, Harvard, Stanford, and MIT alone produced 30 of the 100 top founders. Degrees split too: 55 Europeans stopped at a master’s vs. 18 Americans, while 28 Americans hold an MBA vs. 11 Europeans. 
2. In both the US and Europe, successful founders are seasoned, but not necessarily old. The median US founder had 16 years of work at founding vs. 13 in Europe, and 54 Americans and 43 Europeans had 15+ years of experience. Yet the age split is nearly identical across the Atlantic: about four in ten founded before 35, a third between 35 and 44, and roughly a quarter at 45 or older.
3. Serial founders are common across geographies, slightly more in the US. 63 Americans had founded a company before vs. 51 Europeans, and at least 25 Europeans had already sold or taken public a previous company before starting their current one. 
4. On both sides of the Atlantic, the founder pipeline runs through incumbents. Nearly a third of founders - 32 Europeans, 31 Americans - spent most of their careers in industry or energy before starting up. About seven in ten - 72 Europeans, 66 Americans - worked at a tier-1 employer like Siemens, Shell, or McKinsey. 
5. Europe’s capital is steadier, but concentrated, and founders still look to the US for scaling. Currence data shows European climate funds raised $61bn in 2025 vs. $37bn in the US, with a 71% fund close rate vs. 35%. But the money clusters. European batteries, solar, and low-carbon materials companies still received 58% of the roughly €80bn raised. For scale-up capital, the interviewees pointed west. Tokamak Energy’s David Kingham cited US investors’ higher risk appetite, Cloover’s Jodok Betschart said Europe is “ten years behind the US” on securitization.

Why it matters

The US and Europe are the two most developed markets for climate tech VC, and investors constantly compare where the capital is going, how fast deals close, which region builds faster. AENU’s report helps explain why the same technologies scale differently on each side of the Atlantic, and reveals what the next generation of founders could look like.

The sharp split is at growth funding. Many European companies aren’t leaning on equity. Elvy, which sells Swedish homeowners solar, heat pumps, and batteries on a fixed monthly subscription, raised a roughly $585m debt facility against under $12m of equity. Cloover, a Berlin-based financing platform for home energy installers, paired a $22m Series A with more than $1.3bn in debt backed by a European Investment Fund guarantee. Hometree founder Simon Phelan, who closed the UK’s first residential renewable securitization, says he’d take venture much later if he did it again.

That tracks with our own 2026 Founder Survey with Elemental Impact, in which 73% of founders flagged capital structure as a top financing challenge. Traditional VC wasn’t built for capital-intensive, long-horizon projects, so nearly half (47%) said non-dilutive grants would accelerate their growth, and 29% pointed to blended finance.

What’s next

• Europe’s near-term edge sits in the grid and heavy industry. Europe already leads in deployment for grid infrastructure and long-duration storage, driven by a renewables buildout that needs balancing and a data center boom adding demand. In steel, cement, and process heat, European incumbents are some of the biggest customers. 
• Can Europe keep the next stage at home? After Northvolt, investors are wary of European hardware scale-ups, and the hard-to-abate sectors are still waiting for capital. Formo’s Raffael Wohlgensinger expects Europe to keep its R&D lead while large-scale manufacturing moves to China.

This is a sample of deals available for Currence clients. Can’t get enough deals?

Reading List

💨 The Justice Department asked a federal court to send Interior’s approval of Revolution Wind back for review, putting at risk Orsted’s 704MW offshore wind farm, which has fed power to the Northeast grid since March and installed its last turbine in September. Interior wants to reevaluate whether its 2023 sign-off complied with federal offshore leasing law. [Link]

Offshore wind has been a Trump political target for years. This filing came shortly after Trump agreed to free up 30 stalled wind projects as part of the Senate permitting deal, whose lead Democrat, Sen. Whitehouse, represents Rhode Island, calling the deal into question. 

☀️ In tariff news, the US International Trade Commission ruled that solar cells from India, Indonesia, and Laos hurt US manufacturers, clearing the way to issue duty orders in early November. Combined rates could reach about 268% for Indonesia, 249% for India, and 219% for Laos, on top of existing tariffs. [Link]

Indian and Southeast Asian cell capacity filled the gap after earlier duties hit China. Meanwhile, China’s five largest solar makers cut 40,589 jobs last year as they lost money on rising sales. US developers racing the end-of-2027 placed-in-service deadline for 48E and 45Y will pay more for cells while the global glut deepens.

🔋 Battery storage failures fell 98% per GWh from 2018 to 2025, with stationary systems now failing at 0.04% to 0.14% a year and no US BESS injuries or fatalities reported since April 2019. [Link]

Systems commissioned before 2021 make up 3% of global capacity and carry most of the explosion risk. Community opposition remains after high-profile fires, though, so developers will have to emphasize safety where storage projects keep stalling.

💰 Affordability is driving electrification, from heat pumps to EVs. Canada announced a National Heat Pump Rebate as part of a CAD 2bn (about $1.4bn) plan to retrofit 1m homes over eight years, and US EV sales may be starting to rebound. [Link, Link]

Canada’s rebate covers up to 820,000 households, with CAD 10,000 for below-median-income households and CAD 2,000 for everyone else. The eight-year commitment gives installers a horizon to hire and stock up. In the US, EVs hit 6.5% of new car sales in Q3, their best quarter since the federal tax credit ended last fall, with gas above $4 a gallon driving the market.

💦 A new study finds US households’ drinking water costs are climbing, rising 62% from 2015 to 2025, outpacing both inflation (39%) and grocery prices (30%). [Link]

Water affordability is following the same trajectory as electricity bills, and for overlapping reasons: aging infrastructure, increasing demand, climate stress, and deferred capex all landing on the ratepayer.

🌋 Geothermal has found rare bipartisan support in Washington. The Senate permitting bill gives it more help than wind or solar, and the House passed several of the same provisions this summer with sponsors from AOC to Utah Republican Mike Kennedy. Currence data shows the average winning bid for federal geothermal leases jumped from $10 an acre in 2023 to $182 this year. [Link]

🪨 Frontier made its first purchase of in-situ mineralization, buying $11.7m of removal from 44.01, which injects CO2 into peridotite rock in the UAE to turn it to stone. [Link, read more about Frontier’s newest thesis in CTVC here.]

☀️ Qcells aims to build the world’s first large-scale factory for next-gen tandem solar, as the race to finally scale perovskite-silicon tandem continues. [Link]

🔋 China is getting in on compressed CO2 storage. [Link]

🎬 BBC Earth and Speed & Scale launched Fixing the Planet, a digital series on climate progress. New short films premiere weekly on YouTube through March 2027. [Link, Link]
