Power generation is almost instantaneous. In conventional systems at a instant of time power generated = power consumed. Now a days non-conventional energy sources like solar and wind energy is getting connected with grid. Most of the non-conventional sources are time specific and unreliable in nature. Thus we need a good power storage solution to improve reliability and integrity of the power system. Batteries have been used for many years to store energy. But they are expensive and unsafe. In last decade many scientists ,entrepreneur has come up with different energy storage solutions. Here is the 5 brilliant methods to store solar energy without conventional batteries.
