== Introduction ==
In order to cope with both high and low load situations, the storage of electricity is of great importance. However, the large-scale storage of electricity in the grid is still a major challenge and subject to research and development.

The following technologies and approaches can, or are hoped to, provide a solution to storing electricity and balancing supply and demand in modern electricity grids.

=== Pump storage hydropower ===
A pumped storage hydroelectricity system (PSH) consists of two water reservoirs at different elevations. Low-cost surplus electric power is typically used to pump water into the upper reservoir. During periods of high electricity demand, the stored water is released through turbines to generate electricity.

 Green hydrogen could be used as a long-term storage option: In times of surplus renewable energy, additional unused electricity could be used to produce hydrogen, which would then be stored.

 Hydrogen can also be converted into a liquid for long-term storage, which requires very cold temperatures. Another option would be to convert hydrogen into liquid ammonia with the advantage of using already existing infrastructure for safe storage and transportation.<ref name=":1" />
