Equity for cash Climate & Energy accelerators

These climate and energy programs invest cash in exchange for equity, so they are true accelerators rather than grant programs or fellowships. The checks vary widely, from about $100,000 at the U.S. Venture Sustainability Accelerator to $250,000 at the Cox Cleantech Accelerator, and corporate-backed programs like Halliburton Labs and Evergreen Climate Innovations bring industry access alongside investment. Because each takes equity, read the amount and the reported terms on each record before you apply, and note where the equity percentage is not published.
