"[[w:Energy storage#Chemical|[Storing energy using] hydrogen]] . . . is getting a lot of play now. You could burn hydrogen in a gas turbine to produce electricity. You could use hydrogen in fuel cells that produce electricity without combustion; still a chemical reaction. Or you could simply use hydrogen to create ammonia, NH3, which is another liquid, as opposed to gaseous, chemical storage medium. . . . [E]xperts say that we could probably convert the grid 80% to renewable - that's wind and solar - without having to deal with [the] long-duration storage problem. We'd still use gas peaker plants for . . . 20% of the electricity that we need. If you want to do the other 20%, you're going to have to solve that problem of . . . long-term storage for the grid, days in a row. And you could do that with gravity storage. You could do that with a chemical energy carrier. It's done with methane now. So we've got to get rid of the methane. But you could have hydrogen or ammonia or another chemical energy medium which is yet to be discovered. That's the challenge. We can get to 80%, but we can't get to 100%."
