These systems store excess solar energy during the day and release it when needed, such as at night or during peak demand periods. Battery storage can increase the self-consumption of solar energy, reduce reliance on the grid, and provide backup power during outages.

2. Flow Batteries

Flow batteries are another type of energy storage that is gaining attention. Unlike lithium-ion batteries, flow batteries store energy in liquid electrolytes. This design allows for independent scaling of energy capacity and power output, making flow batteries suitable for large-scale energy storage applications. Flow batteries also have a longer lifespan and are less prone to degradation than lithium-ion batteries.

3. Thermal Energy Storage

Thermal energy storage (TES) systems store energy in the form of heat or cold. TES can be used to store solar thermal energy for later use in heating, cooling, or electricity generation. TES systems are particularly well-suited for applications such as district heating and cooling and industrial process heating.

4. Pumped Hydro Storage

Pumped hydro storage (PHS) is a mature and well-established energy storage technology. PHS systems pump water from a lower reservoir to an upper reservoir during periods of excess electricity production. When electricity is needed, the water is released back down to the lower reservoir, generating electricity through turbines. PHS is a cost-effective solution for large-scale energy storage, but it requires specific geographic conditions.

5. Hydrogen Storage

Hydrogen storage is an emerging technology that holds great promise for long-duration energy storage.
