Climate and cleantech accelerators

Climate accelerators back founders working on energy, mobility, agriculture, and the hard-tech behind decarbonization, often with grant funding and corporate or government partners attached. The specialists are established institutions by now: Los Angeles Cleantech Incubator works with its city on deployment, Elemental Excelerator funds climate projects alongside companies, and Nordic entries like Katapult and the Norrsken Foundation carry the impact end.

These are the climate and cleantech programs we track. See the terms below, or get a personalized match. Hardware-heavy teams should also read the deep tech guide, since programs like HAX overlap both.

Common questions.

Straight answers. For the full picture, read the FAQ.

Frequently, yes. Climate programs are more likely than average to include grants and government-backed support. See the investor directory for non-dilutive climate grants too.

The dedicated names include Los Angeles Cleantech Incubator, Elemental Excelerator, Katapult, and the Norrsken Foundation, with Village Capital covering the impact-investing angle and Bethnal Green Ventures the tech-for-good end. Generalist deep tech programs like SOSV’s HAX take climate hardware as well.

Timelines and buyers differ: climate companies often sell to utilities, cities, or industry, so the good programs bring those counterparties into the room and tolerate hardware development cycles. Expect more grant and blended funding, and milestone support that runs past a three-month demo day.
