Can solar energy be used as a energy storage system?

Existing compressed air energy storage systems often use the released air as part of a natural gas power cycle to produce electricity. Solar power can be used to create new fuels that can be combusted (burned) or consumed to provide energy, effectively storing the solar energy in the chemical bonds.

Which energy storage sub-system is necessary for solar and nuclear energy hybrid systems?

The energy storage sub-system is also usually necessary for solar and nuclear energy hybrid systems. Solar energy sub-system can be chosen to employ either PV or solar thermal technology, and nuclear energy sub-system is always a reactor.

Should solar energy be combined with storage technologies?

Sometimes two is better than one. Coupling solar energy and storage technologies is one such case. The reason: Solar energy is not always produced at the time energy is needed most. Peak power usage often occurs on summer afternoons and evenings, when solar energy generation is falling.
