September 13, 2023

Oakland, CA 13 September 2023 – The California Sustainable Energy Entrepreneur Development (CalSEED) program is thrilled to announce that 27 new Concept awards have been approved by the California Energy Commission (CEC).

For the Concept award, 27 companies out of 153 were selected to receive grants of US$150,000 to develop their breakthrough technologies. In total US$4 million of CEC EPIC funds will be invested in clean energy innovations throughout California.

“The CalSEED program has been successful in helping entrepreneurs working on promising climate solutions to get the support they need to scale up,” said David Hochschild, Chair of the California Energy Commission (CEC).

“Through the California Energy Commission’s EPIC research program, CalSEED is helping entrepreneurs turn great ideas into marketable solutions and providing benefits to California ratepayers.”

Concept awardees went through a rigorous process including a review with CalSEED’s curated review committee, who offered their time and expertise to score applications for technical merit, potential for social impact and energy equity, and team expertise. CalSEED’s solicitation is designed as a call for early-stage clean energy innovations that fall within the following technology areas: energy storage, DER integration and load flexibility, transportation electrification, building decarbonization, and industrial decarbonization.

“We’re thrilled to see so many clean energy entrepreneurs who are not only developing cutting-edge technology, but also thinking about circular and inclusive designs in the way they’re implemented” said Rebecca Lee, Managing Director New Energy Nexus California Programs. CalSEED is a program of New Energy Nexus in California.

Each year the CalSEED program selects new and emerging clean technology areas to fund to help California meet its climate goals. Within the upcoming cohort, 2 out of 27 companies are developing solutions to decarbonize the cement industry, which is currently responsible for 8.8% of industrial sector GHG emissions in California. The potential impact of transforming the way in which one of the most used materials in the world is created is one of the many ways the CalSEED program is working to bring the rapid transformation to a clean energy economy.

“This new cohort of CalSEED grant recipients stands at the forefront of new energy solutions and exemplifies California’s innovative ethos,” said Joy Larson, Program Director of CalSEED.

“With financial support, mentorship, connection to a large network, and the support of a community of fellow entrepreneurs, the CalSEED program offers a springboard for entrepreneurs to bring sustainable energy solutions and energy equity into the energy landscape.”

CalSEED is funded through the CEC’s EPIC program, which invests approximately $120 million annually for innovative clean energy technologies and approaches benefiting. the ratepayers of California’s three largest electric investor-owned utilities.

Details of the 27 companies awarded a total of US$4 million:
