What is energy storage?

Energy storage is a system that can help more effectively integrate solar into the energy landscape. Sometimes it is co-located with, or placed next to, a solar energy system, and sometimes the storage system stands alone.

Why is solar storage important?

Solar storage is important because it allows solar energy to contribute to the electricity supply even when the sun isn’t shining. It also helps smooth out variations in solar energy flow on the grid, which are caused by changes in sunlight.

Should solar energy be combined with storage technologies?

Coupling solar energy and storage technologies is one such case. The reason is that 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.

How is energy stored?

Mechanical Energy Storage: Energy is stored through mechanical means, such as compressing air or using flywheels. Compressed Air Energy Storage (CAES) and flywheels are examples of this technology. Hydrogen Storage: Surplus electricity is used to produce hydrogen through electrolysis.

Can solar energy be used for energy storage?

Solar power can be used to create new fuels that can be stored and later used to provide energy. Existing compressed air energy storage systems often use the released air as part of a natural gas power cycle to produce electricity.

Is energy storage bridging the gap between energy production and consumption?

As the share of variable renewables increases, energy storage is playing an increasingly important role in bridging the gap in time between energy production and energy consumption.
