Dozens of companies will be a part of an upcoming energy-focused conference at Rice University — from climate tech startups to must-see keynote speakers.

The 20th Annual Rice Alliance Energy Tech Venture Forum will take place on September 21 at Rice University’s Jones Graduate School of Business. Anyone who's interested in learning more about the major players in the low-carbon future in Houston and beyond should join the industry leaders, investors, and promising energy and cleantech startups in attendance.

This year's keynote speakers include Christina Karapataki, partner at Breakthrough Energy Ventures, the venture capital fund backed by Bill Gates; Scott Nyquist, vice chairman at Houston Energy Transition Initiative, founded by the Greater Houston Partnership; and Jeff Tillery, COO at Veriten.

Nearly 100 startups will also be pitching throughout the day, and at the end of the program, the most-promising companies — according to investors — will be revealed. See below for the 2023 selection of companies.
