Energy for a rainy day

Los Alamos is giving renewable energy a boost by storing energy from wind power and solar power in the chemical bonds of ammonia molecules.

Energy for a rainy day

Los Alamos materials scientist Fernando Garzon has a plan for national-scale renewable-energy storage.

Energy storage technology to support large-scale wind and solar power
Together, wind and solar power account for only 1.4 percent of U.S. energy consumption because they are intermittent: they go away when the wind and Sun go away. To grow these renewable energy sources, a new energy storage system is needed to capture and release wind- and solar-derived electricity whenever it’s needed. Los Alamos scientists are working on a promising solution: a catalytic electrochemical process that converts renewable-sourced electricity into ammonia fuel, which is stored and subsequently converted back into electricity when needed by an ammonia-fueled fuel cell.
