Solar energy is clean and abundant. But when the sun isn’t shining, you must store the energy in batteries or through a process called photocatalysis — in which solar energy is used to make fuels. In photocatalytic water splitting, sunlight separates water into hydrogen and oxygen. The hydrogen and oxygen can then be recombined in a fuel cell to release energy.
