Power-to-gas (P2G)—the conversion of electrical power into gaseous energy carriers—is a quickly improving and potentially disruptive energy conversion technology. It offers many of the same services of other energy storage technologies and has the added ability to be stored for long periods in the form of a useful commodity fuel product, hydrogen. The hydrogen economy has had false starts before thanks in part to high costs and infrastructure challenges.
