Cohort 3 All Logos

The California Sustainable Energy Entrepreneur Development Initiative (CalSEED) is thrilled to announce the latest recipients of the Concept Award, a grant administered on behalf of the California Energy Commission. CalSEED is an early stage grant funding and professional development program for diverse innovators working to bring clean energy concepts to market.

The California Energy Commission approved $3.75 million in grants for early-stage startups, entrepreneurs and individuals with innovative clean energy solutions. The 25 grants of $150,000 each brings the total number of CalSEED Concept Awards to 71 over the last 3 years.

This year’s Concept Awards represent a portion of the $24 million total to be administered through the CalSEED initiative over 5 years. The innovations receiving awards fall within the technology areas of energy efficiency, renewable generation, and energy storage.

“These 25 companies were selected from 200 applicants for the technical merits of their innovation and potential benefits to California rate-payers when the technology is scaled. The rigor of the selection process is really in our Technical Advisory Committee, which is made up of industry experts in cleantech, social equity, and entrepreneurship. The CalSEED team is very grateful to all of the Technical Advisory Committee members and is excited for this new cohort!” said Joy Larson, CalSEED Program Manager.

In addition to funding, the CalSEED Concept Award includes mentorship, professional business and leadership development, and opportunities to connect with other players in the clean energy ecosystem. CalSEED partners with Cleantech Open, Greenlining Institute and Momentum in conducting outreach to diverse communities and accelerating the Concept Awardees throughout the program. Concept Awardees will also have the opportunity to participate in an annual Business Plan Competition run by CleanTech Open to compete for a Prototype Award, which offers up to $450,000 in additional funding.

The California Sustainable Energy Entrepreneur Development initiative (CalSEED) is made possible by the California Energy Commission and funded through the Electric Program Investment Charge. CalSEED is administered by CalCEF Ventures, an organization of New Energy Nexus.

“We are so excited to be able to work with diverse entrepreneurs striving to bring 100% clean energy to 100% of people,” said Danny Kennedy, Chief Energy Officer at New Energy Nexus. “The technologies emerging in California will support our mission to drive innovation and build equity into the clean energy economy.”
