Accelerating the commercialization of
California’s clean energy tech

Funded by the California Energy Commission, CalTestBed will provide $16.7M in testing vouchers to clean energy innovators to use at one of more than 70 world-class testing facilities throughout California.


Early-stage clean energy entrepreneurs face challenges in accessing testing facilities as they progress towards commercialization.

The CalTestBed Initiative is a voucher program that assists clean energy entrepreneurs in gaining access to critical testing facilities. It expedites their pathway to commercialization through connection to a network of next-level partners.

how it works

Solicitation and Outreach

CalTestBed holds annual soliciations. Each application is reviewed for eligibility and scored by technical reviewers for the following criteria: Innovation, Scalability, Feasibility, and Market Potential.

Laboratory Consultation

Recommended applicants will conduct a consultation with a principal investigator, a campus representative and a neutral subject matter expert to develop a Statement of Work (SOW). The SOW will include scope, schedule and budget for the testing. Once the California Energy Commission reviews and approves the proposed SOWs, those voucher recipients will sign the contracting package and will work with their testing facility partners to schedule and begin their testing.

Customer Development and Commercialization

The CalTestBed Initiative hosts an annual symposium to bring the community together, feature voucher recipients, highlight our world-class testing facilities, and connect the innovators to next-level partners. The Initiative will also spotlight voucher recipients and their innovations through a variety of media and events throughout the year.
