- At this point, when you hear “venture capitalist,” you probably think of … software. Or artificial intelligence. Or cryptocurrency.
The Engine Ventures, which spun out of MIT a few years ago, is different. It tries to fund what it calls “tough tech,” a somewhat nebulous category that includes companies working in energy, decarbonization, health, and infrastructure. As such, it’s backed some of the most interesting “climate tech” companies in business today, such as Form Energy, Commonwealth Fusion.
On this episode of Shift Key, Rob chats with Katie Rae, the CEO and managing partner of Engine Ventures. They chat about what’s missing from America’s innovation ecosystem, how close fusion is to succeeding, and whether AI is a bubble (whatever that might mean).
One more note: Early in our conversation, Katie says that Commonwealth Fusion has built “more than 300” tokamak reactors. That was, unfortunately, an overestimate. It’s actually built closer to more than 150 reactors. Her team contacted us after her appearance to correct the record.
Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap News.

03/08/2026 | 33 minThe Democratic Party’s climate and energy policy is at a difficult moment. Over the past year and a half, the Trump administration has attacked solar and wind energy, started an inflationary war, and repealed key parts of the Inflation Reduction Act. And about a year and a half from now, Democrats will pick a presidential candidate and pitch their energy and climate policies to voters again.
How are key Democrats feeling at this moment? Rob recently had a chance to sit down with two of the party’s most important energy policy makers — Senator Martin Heinrich of New Mexico, the ranking Democrat on the Senate Energy and Natural Resource Committee, and former Energy Secretary and Michigan Governor Jennifer Granholm — for an in-person conversation in Washington, D.C.
On this episode of Shift Key, Rob chats with Senator Heinrich and Secretary Granholm, about fuel prices, the state of permitting discussions, AI data centers, and what each learned from writing — and implementing — the Inflation Reduction Act.

Hosted on Acast. See acast.com/privacy for more information.- There’s really one one good thing that could happen this year in Congress for clean energy: permitting reform. If lawmakers reached a bipartisan deal on the country’s permitting system, they could make it easier to build solar, wind, and transmission lines — as well as every other kind of infrastructure.
But will it happen? What are the obstacles to a deal? What would be in a deal? On this episode of Shift Key, Rob is joined by Daniel Palken, the director of infrastructure for energy and permitting at Arnold Ventures. They discuss the recent history of permitting reform, the policies that would probably make up a deal, and why it might be now or never for reforming the permitting system.

They’re scaling up fast and recently announced a new $20 million debt facility with JP Morgan; the bank also agreed to buy more than 60,000 tons worth of removals from them.
On this episode of Shift Key, Rob is joined by Peter Reinhardt, the CEO and cofounder of Charm. (He’s also the CEO of the trucking company Revoy, a founder of the autoimmune therapeutics company Antipode, and a board member at the electricity data company Arcadia.) They talk about what makes Charm different, how it is scaling operations as a carbon removal company, and the changing politics of climate change.

Hosted on Acast. See acast.com/privacy for more information. - For more than 30 years, a heterodox group of scientists have proposed injecting sulfate aerosols into the stratosphere to reflect sunlight away from Earth, thereby cooling the atmosphere and reversing climate change.
But actual research into the idea has remained taboo, or at least the province of university and government labs. Then, last year, Heatmap broke the story of an Israeli-American company named Stardust Solutions that had raised $60 million to develop a new solar geoengineering technology. This system would be easier to control and track than the traditional approach to geoengineering, it claims.
On this episode of Shift Key, Rob is joined by Yanai Yedvab, the cofounder and CEO of Stardust. They discuss why Stardust is researching geoengineering now, whether a for-profit company belongs in the space, why Yanai believes Stardust’s particles are superior to sulfate aerosols, and whether Stardust has or will ever conduct outdoor experiments.
