The 12-week accelerator provides startups access to Rice Alliance's network of energy corporations, investors, and advisors. With an engaged support network and personalized mentor relationships, startups will also experience curriculum and programming intentionally designed to increase their likelihood of success—bridging the gap between ideas and business success. Once through the program, startups will be better positioned to attract capital and launch pilot programs and other initiatives, which can be facilitated through accelerator connections.

The accelerator will culminate in a Demo Day in conjunction with the 19th annual Rice Alliance Energy Venture Forum that brings together more than 700 members of the energy industry including investors, corporations and real opportunities for selling your business. The Accelerator is part of The Ion's Accelerator Hub, along with The Ion Smart City Accelerator and DivInc's accelerator, which will provide startups a wider network, support system and extended reach. Rice Alliance has relationships with every major energy corporation in Houston and strong collaborations with energy investors.


Launching virtually in June 2021, the Rice Alliance Clean Energy Accelerator is open to any early-stage startups that contribute to significant energy efficiency improvements, are developing energy derived from renewable, zero-emissions sources or are curbing the environmental impact of all types of energy production, distribution or usage, or enabling progress toward net zero carbon.

The inaugural class will launch virtually in June and wrap up in September. All programming and content will be delivered virtually. However, pending status of the pandemic and safety there may be an opportunity for portions of the demo day to include in-person activities and participating startups could be invited to pitch in Houston.


Startups should be prepared to dedicate two full days a week to participating in meetings and mentor office hours each week, but keep in mind that some weeks will require more meeting time. In addition, there will be supplemental activities outside of scheduled virtual meetings to aggressively accelerate your startup. It is preferred that participating founders attend all scheduled sessions and workshops. In the event that is not possible, at least one founder from each startup team must be present.
