    Accelerating the energy transition

    The Rice Alliance Clean Energy Accelerator is for 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.

    We are the perfect fit for early-stage startups from seed stage to Series A with a technology solution in Alternative Fuels, Biomass Energy, Carbon Neutrality, Management or Accounting, Digital Technologies for Energy, Energy Efficiency or Storage, Geothermal Energy, Hydrogen, Nature-based solutions for carbon footprint reduction, Solar Energy, Waste Heat to Power or Wind Energy. We are looking for companies that have demonstrated the feasibility of their technology/solution and are looking to scale or refine (TRL 3 to 7).


    In collaboration with Wells Fargo, the Rice Alliance Clean Energy Accelerator was concepted in 2019. Coupled with a long history of supporting energy entrepreneurs and a robust network of energy investors and corporations, the Rice Alliance set out to expand a commitment to supporting bold entrepreneurs and accelerating the energy transition.

    Knowing no impactful effort is ever achieved alone, the energy companies in Houston jumped in to support the success of the accelerator—and in the Summer of 2021, the first cohort was deployed.

    43 Ventures

    Since launching, 43 ventures have benefitted from participating in the program through three classes.
