Southern California Gas Co. (SoCalGas) and San Diego Gas and Electric (SDG&E) have created a Hydrogen Blending Demonstration Program that will be the first of its kind in California and among the first in the nation.
Blending hydrogen with natural gas is part of a multi-pronged strategy both utilities – subsidiaries of Sempra Energy – are undertaking to decarbonize their natural gas grid. The vision is to leverage surplus renewable electricity generated in the middle of the day to produce green hydrogen, which then can be injected into the natural gas grid for storage and use. SoCalGas, in partnership with the National Fuel Cell Research Center and the University of California Irvine, is developing the technology. Hydrogen blending is another important milestone for providing the clean fuel needed to achieve California’s climate goals while maintaining an affordable, resilient and reliable energy system.
