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 . However, they note, a clean US hydrogen economy will require a comprehensive strategy and a 10-year plan. The commentary suggests that careful consideration of future hydrogen infrastructure, including production, transport, storage, use, and economic viability, will be critical to the success of efforts aimed at making clean hydrogen viable on a societal scale.
