CalSEED awards US$6.6 million in grants to early-stage clean energy innovations

May 13, 2022

30 clean energy startups were selected to receive funding of either US$150,000 for their concepts or US$450,000 for their prototypes.

Oakland, CA 11 May 2022 The California Sustainable Energy Entrepreneur Development (CalSEED) program is thrilled to announce that two new cohorts of Concept and Prototype awards have been approved by the California Energy Commission (CEC).

For the Concept award, 23 companies out of 166 were selected to receive grants of US$150,000 each. For the Prototype award, 7 companies out of 22 were selected to receive another $450,000 to continue to develop their breakthrough technologies. In total US$6.6M of CEC EPIC funds will be invested in clean energy innovations throughout California.

“We are grateful to the CEC’s visionary leadership and partnership in supporting early-stage energy innovators with critical and timely funding,” said Denise Rushing, Managing Director of California, New Energy Nexus. “The 30 companies gaveled in today represent the diversity of California and our state’s mission to prioritize energy solutions that accelerate the transition to a clean energy economy for everyone.”

Concept awardees went through a rigorous process including a review with CalSEED’s curated review committee, who volunteered their time and expertise to select the most promising clean energy technologies of the future. CalSEED’s solicitation is designed as a call for early-stage clean energy innovations that fall within the following technology areas: energy efficiency, load modifying, energy storage, grid enhancements, renewable energy, electric vehicle charging and powertrain technologies, advanced technologies that enable
water savings.

CalSEED’s success is in supporting the best and boldest clean energy innovations while advancing equity and driving gender diversity into our programming.

“I am proud to say that the 30 companies selected today represent women and other diverse leaders amongst their CEOs, with at least 5 of the 23 concept awardees having women founders and/or women in leadership positions,” said Sarah Chester, Director of Grants Compliance, CalSEED. “This number is super impressive given the national average is that less than 2% of all tech startups have women founders nationwide. I am thrilled to begin working with these change makers who will be instrumental in advancing California’s transition to a clean energy future.”

While soliciting for CalSEED’s 5th Concept award cohort, the team also coordinated with Cleantech Open (CTO) to oversee the annual business plan competition. Eligible CalSEED Concept Awardees from cohort 3 and 4 participated in CTO’s accelerator program, where they receive tools and insights to develop a business plan that becomes the basis of the competition’s application package. The panel of judges was comprised of 19 members of the CalSEED Review Committee, representing expertise in start- ups, experience with industry-specific commercialization, and the ability to evaluate social and environmental impacts. The selected companies are focusing their efforts on solutions for batteries, storage, energy efficiency and renewable generation – areas that are critical to meeting California’s climate goals.

“CalSEED has provided entrepreneurs with the funds and resources they need to explore their innovative concepts,” said Josh Croft, Energy Deployment and Market Facilitation Officer of the CEC. “It’s exciting to imagine what the future of energy will be and how Californians will be a part of it.”

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

This additive manufacturing approach directly deposits a layer of silicon microparticles to a surface that absorb sunlight and convert it to electricity, achieving the same performance and reliability as traditional solar cells at half the cost using entirely local supply chains. This unique combination leaps the barriers of thin margins and supply chain disruptions and enables sustainable growth of solar manufacturing. Furthermore, this additive manufacturing process makes direct integration of solar energy generation with new products like vehicles and roofing materials easier, opening new markets for solar energy.

Parthian Energy is developing a new class of advanced battery sensors, with applications in quality control at manufacturing, ultrafast charging during operation, and evaluating second life capabilities. The Parthian Electromagnetic Sensor, or PES detects internal defects in lithium-ion battery cells, either during manufacturing or during operation, by evaluating the change in the battery’s electromagnetic signature. This reduces unnecessary scrap, enhances safety, and enables higher energy density cells to be deployed into EVs and Grid Storage with much less risk of thermal runaway. PES also provides cell makers with dramatic reductions in work-in process inventory, working capital costs, and facility costs. In addition, PES provides faster and lower cost battery Q.C., which drives shorter design cycles and faster time-to market.

RePurpose is developing a system that tests, reassembles, and redeploys used electric vehicle batteries to store solar energy, creating create lower-cost, more sustainable energy storage systems. The process begins by precisely measuring EV battery health in <90 seconds using machine learning. Then battery reassembly is optimized into new circuits to maximize safety, efficiency, and longevity. Finally, the batteries are equipped with proprietary controls and fire suppression systems. This allows for repurposing used EV batteries safely for 7-10 years in “second-life” energy storage systems at around half the cost of new battery alternatives.

Tolo pairs state-of- the-art cameras with unmanned aerial vehicles (UAVs) and collects thousands of detailed photos from every angle of a utility tower, capturing images at greater detail than what is visible to an inspector in the field. A novel software application, custom-built for utility inspectors, provides advanced tools and greater inspection freedom and flexibility than field inspection. The result is more accurate, sharable, monitorable inspections that drive better maintenance decisions, reduce utility-caused wildfires, and enhance grid reliability.
