2. Pumped Hydro Storage: Pumped hydro storage is another method of storing solar energy. It involves using excess energy generated by solar panels to pump water from a lower reservoir to a higher one. When energy is needed, the stored water is released, flowing down to the lower reservoir and passing through turbines to generate electricity.
3. Thermal Energy Storage: Thermal energy storage is a method that uses excess solar energy to heat or cool a medium, such as molten salt or water. The stored thermal energy can then be used to generate electricity or provide heating and cooling in buildings.
4. Hydrogen Production: Hydrogen production is a process that converts excess solar energy into hydrogen gas through a process called electrolysis. The hydrogen can be stored and used as a fuel source for various applications, including generating electricity through fuel cells or powering vehicles.
Here’s a table summarizing the methods of solar energy storage:
