Solar energy can be stored as hydrogen through a process called electrolysis, where electricity from solar panels splits water into oxygen and hydrogen gas. The hydrogen gas can then be stored under pressure, or in a metal hydride, and converted back into electricity when needed through fuel cells. [pdf]
