The project showcases how leveraging existing infrastructure with electrolyzers and fuel cell technology may be able to create microgrids that deliver resilient power and can help to safeguard businesses, communities, and campuses from power disruptions. If developed at scale, this technology may help further California Governor Gavin Newsom's recent strategic initiatives to develop a hydrogen economy.
"It is becoming clearer with each passing day that hydrogen can and should play a key role in California's efforts to reduce our reliance on fossil fuels," said Senator Bob Archuleta, Chair of the Senate Select Committee on Hydrogen Energy. "Moreover, I am excited to see Caltech, one of our nation's leading institutions, serving as a testbed for the use of hydrogen with this new and innovative technology on their campus."
"This collaborative effort represents a significant step in harnessing hydrogen as a resilient, clean energy solution that's in line with Governor Newsom's vision for California," said Maryam Brown, President at SoCalGas. "Integrating cutting-edge electrolyzers and fuel cell technology into existing infrastructure demonstrates the potential for building robust microgrids, enhancing power resiliency for businesses, communities and campuses at scale."
This project takes water from Caltech's service line and runs it through Bloom Energy's solid oxide electrolyzer, which uses grid energy to create hydrogen. The resulting hydrogen is injected into Caltech's natural gas infrastructure upstream of Bloom Energy fuel cells, creating up to a 20% blend of hydrogen and natural gas. All of this fuel blend is then converted into electricity with Bloom Energy's fuel cells, and the electricity is then distributed for use on campus.
Blending hydrogen into natural gas infrastructure statewide – which could help reduce dependence on fossil fuels and ultimately drive down hydrogen costs by scaling production – first requires developing a hydrogen injection standard.
The global hydrogen economy is projected to potentially produce as much as 80 gigatons of carbon abatement by 2050, which represents approximately 11% of required cumulative emissions reductions.1
SoCalGas is working to help develop a state hydrogen blending standard by proposing pilot projects for approval by the CPUC. These projects could help to better understand how clean fuels like clean renewable hydrogen could be delivered through California's natural gas system.
Just this year, SoCalGas unveiled its award winning H2 Innovation Experience, a state-of-the-art demonstration project designed to show the potential resiliency and reliability of a hydrogen microgrid.
When coupled with renewable energy, clean hydrogen could help facilitate a scalable, resilient and decarbonized energy system. SoCalGas is working to help shape California's 21st century energy system through investments in hydrogen, renewable natural gas, fuel cells and carbon management.
