Hydrogen Energy Storage: Grid and Transportation Services (Technical Report): NREL (National Renewable Energy Laboratory)

Marc Melaina, Joshua Eichman

Research output: NRELTechnical Report


Proceedings of an expert workshop convened by the U.S. Department of Energy and Industry Canada, and hosted by the National Renewable Energy Laboratory and the California Air Resources Board, May 14-15, 2014, in Sacramento, California, to address the topic of hydrogen energy storage (HES). HES systems provide multiple opportunities to increase the resilience and improve the economics of energy sup supply systems underlying the electric grid, gas pipeline systems, and transportation fuels. This is especially the case when considering particular social goals and market drivers, such as reducing carbon emissions, increasing reliability of supply, and reducing consumption of conventional petroleum fuels. This report compiles feedback collected during the workshop, which focused on policy and regulatory issues related to HES systems. Report sections include an introduction to HES pathways, market demand, and the 'smart gas' concept; an overview of the workshop structure; and summary results from panel presentations and breakout groups.
