The 20th Annual Rice Alliance Energy Tech Venture Forum , which unites energy ventures with industry investors, is returning Thursday, September 21, at Rice University’s Jones Graduate School of Business.

For two decades, the Energy Tech Venture Forum — hosted by the Rice Alliance for Technology and Entrepreneurship — has served as the premier conference, bringing together energy industry leaders, venture capital investors, and promising energy and cleantech ventures to propel the future of energy.

Across interactive panels, keynotes speeches, and venture pitches, attendees can explore emerging energy sources, enhancements and efficiencies within existing energy resources, and advances in clean or renewable technologies — and, perhaps most importantly, learn where investors are contributing to the acceleration of these advancements.

More than 90 startup technology ventures commercializing energy transition innovations will participate and meet investors looking for disruptive energy technologies that can accelerate clean and renewable energy.

The full list of both presenting companies and pitching startup can be found here .

Keynote speakers include:

• Christina Karapataki , partner at Breakthrough Energy Ventures, the venture capital fund cofounded by Bill Gates
• Scott Nyquist , vice chairman at Houston Energy Transition Initiative, founded by the Greater Houston Partnership
• Jeff Tillery , chief operating officer at Veriten, founded by Rice alumus Maynard Holt, formerly with Tudor Pickering Holt

The event also includes pitches from Rice Alliance’s Clean Energy Accelerator Class 3 Demo Day , plus the announcement of “Most Promising Company” chosen by the energy tech industry experts and participating investors.
