يتعلم أكثرWhy does steam store large amounts of energy?
Steam is formed when these bonds are broken and each H2O molecule moves further apart from their neighbouring molecules. But hydrogen bonds are strong. Thus in order to break these bonds, large amounts of energy must be supplied to liquid water inorder to convert it to steam. And this large amounts energy is thus stored in …

By comparison, coal, one of the worst fossil fuels, provides 24MJ/kg heat, or about 10MJ electrical (not all heat becomes electricity). So to store the energy from 1kg of coal, you''d need 10kg of lithium batteries. And it takes a lot of coal to keep power plants running - fields and fields of coal piled up and waiting.
