Southern California’s clean energy grid faces mounting reliability challenges from extreme weather and surging electricity demand, prompting a major policy push toward green hydrogen to back up intermittent solar and wind power. According to Ernesto Medrano, executive secretary of the Los Angeles/Orange Counties Building and Construction Trades Council, renewable electricity alone cannot decarbonize heavy-duty sectors like maritime shipping, aviation, and port operations, making carbon-free hydrogen an essential tool for the region’s energy future.
While solar and wind generation continue to expand across the region, mismatched supply and demand have driven growing curtailment of solar energy. Meanwhile, extreme heat waves, wildfires, and rising electricity needs from data centers and electric vehicles strain the power sector. Natural gas currently provides the firm, dispatchable power needed when the sun isn’t shining and the wind isn’t calm, but state and local leaders are moving to replace fossil fuels with green hydrogen.
Did You Know? On June 29, California’s Renewables Portfolio Standard added renewable hydrogen use in gas turbines as an eligible resource following the signing of SB 1350 into law by Gov. Gavin Newsom.
Regulatory Milestones and Shovel-Ready Projects
Recent policy actions at both the state and municipal levels have established a clear framework for integrating green hydrogen into the local power grid. The Playa del Rey power facility operated by the Los Angeles Department of Water and Power (LADWP) saw its modernization efforts advance earlier this month when the final Environmental Impact Report for the Scattergood Generating Station Repowering Project was approved by the Los Angeles City Council, setting the stage to swap natural-gas steam for a minimum of 30% green hydrogen.
On the development front, projects such as the Lancaster Clean Energy Center have already safe-harbored $1.8 billion in federal tax credits. Built around 694 megawatts of solar and 900 megawatts of battery storage, the Lancaster facility represents more than 1,200 high-skilled union careers and demonstrates the shovel-ready nature of the region’s clean energy transition. According to industry advocates, green hydrogen can displace fossil gas in all existing Southern California turbines by up to 45% by volume using current infrastructure once long-term offtake contracts are secured.
Expert Insight: Integrating green hydrogen into existing power generation infrastructure offers Southern California a practical bridge toward its 2035 carbon-free goals. By serving as long-duration energy storage that banks excess solar power for weeks at a time, hydrogen addresses the core intermittency problem facing modern renewable grids while simultaneously establishing a scalable fuel source for transit and port operations.
Economic Impacts and Future Regional Strategy
Proponents emphasize that transitioning to green hydrogen will drive meaningful job creation and expand the middle class through local, highly skilled labor and apprenticeship opportunities. Medrano notes that the workforce building these projects comes from diverse backgrounds, including communities historically left out of California’s clean energy economy. Scaling green hydrogen in the power sector could subsequently lower costs and drive adoption across transit buses, heavy-duty trucks, and port operations.
Frequently Asked Questions
What is green hydrogen?
Green hydrogen is a carbon-free fuel produced from renewable electricity and water that can displace fossil fuels in power plants, trucks, and port operations.
How does SB 1350 impact California energy policy?
Signed by Gov. Gavin Newsom on June 29, SB 1350 formally recognizes the use of renewable hydrogen in gas turbines as an eligible resource under California’s Renewables Portfolio Standard.
What changes are planned for the Scattergood Generating Station?
Aiming to modernize the LADWP-operated power plant in Playa del Rey, the Scattergood Generating Station Repowering Project received final Environmental Impact Report approval from the Los Angeles City Council to substitute at least 30% green hydrogen in place of natural-gas steam.
How will local agencies in Los Angeles coordinate the deployment of green hydrogen across power, transit, and port sectors?
