San Diego Gas & Electric Co. on April 19 announced plans to break ground on an energy storage project and build two hydrogen projects as part of its plan to reach net-zero emissions by 2045.
The Sempra Energy subsidiary will break ground this month on the 20-MW/80-MWh Kearny Energy Storage project in San Diego, Calif. The project is expected to reach commercial operations in late summer or early fall.
The utility, known as SDG&E, is building two additional storage projects that will bring its overall electric storage portfolio to 135 MW, according to a news release. The 30-MW/120-MWh Top Gun Energy Storage project in the Miramar area of San Diego is expected to be operational in June, while construction on the 40-MW/160-MWh Fallbrook Energy Storage project in unincorporated North San Diego County is expected to begin by early 2022 at the latest.
Additionally, the company is developing two hydrogen projects, and construction on both is expected to start this year. SDG&E is developing the Borrego Springs Green Hydrogen Project to demonstrate hydrogen’s use as long-duration energy storage, as a microgrid asset and as a resource for dispatch by the California ISO to support grid reliability.
The Palomar Green Hydrogen Systems Project will demonstrate blending of hydrogen with natural gas as fuel for electric generation and on-site production of green hydrogen for use as a cooling gas. The company will also install its first hydrogen fueling station to support the first fuel cell vehicles in its fleet.
