Materials scientist and engineer Sossina Haile couldn’t have predicted that the cost of solar and wind energy would plummet in recent years, or that places like California would start paying customers to take electricity because their supply outstripped demand. But once those things happened, she had a solution.
Haile’s team developed a way to convert electricity into hydrogen, store it and convert it back to electricity when more is needed. This breakthrough offers a way to rebalance, and even stabilize, the U.S. energy grid.
