How to Fund the Future of Climate Tech

Tom Steyer is still riding the wave.

The climate investor and philanthropist told the audience at Heatmap House’s third session of the day, “Up Next in Climate Tech,” that he started his investment firm Galvanize in 2021 because “there’s a huge, powerful wave behind us.” And now, after the One Big Beautiful Bill Act and the Trump administration’s regulatory assault on renewables? “Does any of that change? No, it’s better,” Steyer said.

Steyer was skeptical that the oil and gas industry could ultimately compete with clean energy, even with the current administration’s support.

“For the people who never look at the numbers, for the people who don’t pay attention to actual investment decisions, costs, profit margins, you can say whatever you want. But I’ll tell you this: The rig count is down 10% to 20% in 2025 in America. That’s a statement about future profitability” of the oil industry Steyer said, pointing to declining domestic drilling.

For Steyer, the math is simple. A huge portion of demand for oil comes from the transportation sector, and the movement towards electric vehicles is “unstoppable.”

“We’re talking about a commodity with a worldwide price where we’re the biggest producers of oil in the world,” Steyer said. He noted that the U.S. is also the “high-cost producer” compared to countries like Saudi Arabia, which can produce oil more cheaply than in the U.S. shale patch.

So if there’s such a huge market opportunity for clean energy businesses, can they get funded? That’s the challenge fellow investor Dawn Lippert is trying to solve. Lippert is the founder and chief executive of Elemental, a non-profit climate investment firm, and a founding partner of Earthshot Ventures, a venture capital firm. The trick she’s trying to perfect is to attract investors beyond the specialized, earlier stage investor group that typically seeds decarbonization, who can fund actual, steel-in-the-ground projects.

“We are trying to finance the energy transition with venture capital,” referring to the broader financing community. “It’s a total mistake.”

Venture capital has catalyzed “a huge wave of technology, invention, and technologies that are really working,” Lippert added. What’s happening now is that those companies are “trying to deploy, they’re trying to build their first plants, trying to build their second plants. It takes quite a lot of capital, and there’s no one to hand it out on the financial infrastructure side. They’re not ready for infrastructure investors. They’re definitely not ready for banks.”

This problem of “bankability,” or the “missing middle,” has bedeviled the climate tech sector for years, as technologically innovative energy projects struggle to get funding from infrastructure investors who want projects that can produce predictable cash flows, not risky venture-stage experiments.

Elemental developed an investment vehicle called a D-SAFE — a.k.a. a Development Simple Agreement for Future Equity — to help solve this problem. The D-SAFE is an investment agreement that can unlock future investment by pointing investment directly at development costs. “A development SAFE says, I’m going to give you dollars, and I’m going to get those dollars back when you hit specific milestones,” Lippert said.

So far, Elemental has done nine D-SAFEs. “We’re trying to create much simpler financial infrastructure so that financial innovation can catch up to where technology innovation is, and we can stop slowing things down,” Lippert said.

The challenge for American climate technology and infrastructure companies will be to compete with state-supported Chinese businesses, Lippert said. “China actually does have a very methodical way of putting a ton of state capital into these companies to get them all the way through. We don’t have that in this country, so we have to be much more creative and make sure that companies where technology is working are not falling into a scale gap just because we can’t get our act together.”
