The Los Angeles region is setting some precedents in advancing clean energy projects in one of the largest U.S. metropolitan areas, with efforts underway that include startup early next year of one of the nation's first utility-scale power plants fueled by 30% hydrogen.

L.A.-area public agencies and companies are working to produce and transport cleaner sources of hydrogen fuel to cut emissions in natural gas power plants and in hard-to-decarbonize sectors in southern California, according to public agency and company officials who spoke at the ENR LA Infrastructure Forum this month.
