What is a sand battery?

The Sand Battery provides low-emission energy, supporting the expansion of solar and wind power without toxic or harmful materials. Our thermal energy storage ensures high security of supply and increases energy self-sufficiency. It can be activated automatically and features a long design life.

What is an energy storage system?

The Energy Storage System is used to capture electricity produced by both renewable and nonrenewable resources and store it for discharge when required. The system allows users to go off grid and switch to stored electricity at a time most beneficial, giving greater flexibility and control of electrical usage.

What is thermal energy storage?

Our thermal energy storage ensures high security of supply and increases energy self-sufficiency. It can be activated automatically and features a long design life. It can be charged with low-cost grid electricity or self-generated power, and enables participating in grid balancing markets for additional revenue.

What is energy storage & how does it work?

Energy storage provides a fast response and emission-free solution. Restore and balance between supply and demand, the storage system is charged or discharged in response to an increase or decrease of grid frequency and keeps it within pre-set limits. The typical electricity demand curve usually doesn’t meet the PV generation curve.
