Energy researchers: clean US hydrogen economy is within reach, but needs a game plan

Green Car Congress

Addressing climate change requires not only a clean electrical grid, but also a clean fuel to reduce emissions from industrial heat, long-haul heavy transportation, and long-duration energy storage. Hydrogen and its derivatives could be that fuel, argues a commentary by four energy researchers in the journal Joule.
