– As part of their commitment to support California’s climate goals and their mission to become the cleanest, safest and most innovative energy companies in America, Southern California Gas Co. (SoCalGas) and San Diego Gas and Electric (SDG&E) today announced the creation of a Hydrogen Blending Demonstration Program. This program would be the first 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. Power-to-gas technology is being developed to do just that. SoCalGas, in partnership with the National Fuel Cell Research Center, and University of California Irvine , is leading the way in developing this technology, launching the first power-to-gas demonstration project in the United States in 2015. 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.

When adopted by the California Public Utilities Commission (CPUC), the demonstration program will provide an understanding of how to safely incorporate hydrogen, a zero-emission fuel, into the gas grid. This is the first step toward the establishment of a statewide hydrogen injection standard.

“Our California-based utility businesses are helping build California’s 21st century energy system through deliberate investments in hydrogen, renewable natural gas, fuel cells, and carbon capture and storage,” said Kevin Sagara , group president for Sempra Energy and chairman of SoCalGas and San Diego Gas & Electric. “This hydrogen blending program is a key milestone in our efforts to decarbonize our energy system, while delivering affordable and reliable energy to 22 million California customers.”

“Green hydrogen is a game-changer, not only for our power and energy needs, but also for our industrial and transportation sectors,” said Sen. Nancy Skinner (D- Berkeley ). “And green hydrogen can support existing, good-paying jobs as our state and communities take steps to transition to a zero-carbon economy.”

“Today’s announcement is an exciting development for California’s emerging renewable hydrogen market,” said Bill Zobel , Executive Director of the California Hydrogen Business Council. “The Hydrogen Blending Demonstration Program will help the public understand that renewable hydrogen is important and a valuable tool for our carbon neutral future.”

SoCalGas and SDG&E are planning multiple hydrogen blending projects throughout their respective service territories. The first proposed project will blend hydrogen into an isolated section of primarily polyethylene (PE) plastic distribution system in SoCalGas’ service territory. The initial hydrogen blend level is planned at 1% and may increase to as much as an industry-leading 20%.

SoCalGas expects to choose the location of the initial project in early 2021.

Subsequent projects are scheduled in SDG&E’s service territory and will build upon the knowledge learned in the first demonstration. This includes blending hydrogen into an isolated section of mixed plastic and steel natural gas distribution system, and an isolated steel pipeline demonstration.

In addition to these hydrogen blending projects, SDG&E announced in October that it intends to pilot two hydrogen projects by 2022 as part its comprehensive sustainability strategy to advance carbon neutrality. These two projects would use a combination of technologies such as renewable resources, electrolysis and fuel cells to demonstrate increased system resiliency, long-duration storage, power-to-gas hydrogen fuel blending, and vehicle hydrogen fueling, among other applications.

SoCalGas is helping to build California’s 21 st century energy system with investments in hydrogen, renewable natural gas, fuel cells and carbon capture and storage. These innovations will help the utility decarbonize its pipeline system. Last year, SoCalGas set a goal to deliver 5% renewable natural gas (RNG), produced from organic waste, to its core customers by 2022 and 20% by 2030. SoCalGas and SDG&E are also seeking CPUC approval of a program that will offer customers the option to purchase RNG as part of their natural gas service. The program is set to be voted on by the CPUC in December.

The Hydrogen Blending Demonstration Program is part of a joint application filed with the California Public Utilities Commission (CPUC) by SoCalGas, SDG&E, Pacific Gas and Electric (PG&E) and Southwest Gas in accordance with the Biomethane Order Instituting Rulemaking (Biomethane OIR).

About SoCalGas
Headquartered in Los Angeles, SoCalGas® is the largest gas distribution utility in the United States. SoCalGas delivers affordable, reliable, clean and increasingly renewable gas service to 21.8 million customers across 24,000 square miles of Central and Southern California, where more than 90 percent of residents use natural gas for heating, hot water, cooking, drying clothes or other uses. Gas delivered through the company’s pipelines also plays a key role in providing electricity to Californians— about 45 percent of electric power generated in the state comes from gas-fired power plants.

SoCalGas’ vision is to be the cleanest gas utility in North America , delivering affordable and increasingly renewable energy to its customers. In support of that vision, SoCalGas is committed to replacing 20 percent of its traditional natural gas supply with renewable natural gas (RNG) by 2030. By developing renewable gas from our state’s abundant organic waste streams, we can help to meet our climate goals sooner, while diversifying our carbon-free energy sources, improving energy resilience and reliability, while also creating additional renewable fuel and jobs for our communities. SoCalGas is also committed to investing in its gas delivery infrastructure while keeping bills affordable for our customers. From 2014 through 2018, the company invested nearly $6.5 billion to upgrade and modernize its pipeline system to enhance safety and reliability. SoCalGas is a subsidiary of Sempra Energy (NYSE: SRE), an energy services holding company based in San Diego.
