SoCalGas proposed what could be the largest green hydrogen infrastructure in the nation, with pipelines moving hydrogen from desert solar farms to Los Angeles.

The Green Hydrogen Coalition sees the nation’s seaports, heavy with air pollution, as an ideal starting place for a hydrogen fuel revolution to begin.

The widespread adoption of green hydrogen will depend on construction of “ecosystems” that span sectors and geographic boundaries, industry supporters say.

There’s a growing consensus in the West that green hydrogen could play a key role in decarbonizing the region’s energy system, but questions still loom around exactly how the fuel will be used in that effort.
