6. One can store energy by compressing air, and then later use it to power a turbine to create energy when needed However, you have to heat the room temperature compressed air to make this effective. You can avoid this if you initially compress the air under adiabatic conditions, so the gas is already hot when you need it to generate electricity This is called adiabatic compressed air energy storage (CAES). Inside a typical power plant, 5.8x10° kg of N2...
