Hydrogen and other energy-carrying chemicals can be produced from a variety of energy sources, such as renewable energy, nuclear power, and fossil fuels. Converting energy from these sources into chemical forms creates high energy density fuels. Hydrogen can be stored as a compressed gas, in liquid form, or bonded in substances. Depending on the mode of storage, it can be kept over long periods.
After conversion, chemical storage can feed power into the grid or store excess power from it for later use. Alternatively, many chemicals used for energy storage, like hydrogen, can help decarbonize industry and transportation. The flexibility of being able to feed stored energy back into the grid or sell the produced chemical into industrial or transportation applications provides additional opportunities for revenue and decarbonization not open to other storage devices like batteries.
