Temperatures can be hottest during these times, and people who work daytime hours get home and begin using electricity to cool their homes, cook, and run appliances. Storage helps solar contribute to the electricity supply even when the sun isn''t shining. It can also help smooth out variations in how solar energy flows on the grid.

Currently lots of options are being explored, for example, using hydrogen to store energy which can then be used in power stations to make electricity to use on the system. We can create huge caverns underground and fill them with hydrogen, storing very large amounts of energy, for very long time periods.

The existing 161,000 megawatts (MW) of pumped storage capacity supports power grid stability, reducing overall system costs and sector emissions. A bottom up analysis of energy stored in the world''s pumped storage reservoirs using IHA''s stations database estimates total storage to be up to 9,000 gigawatt hours (GWh).

A battery energy storage system (BESS) is an electrochemical device that charges (or collects energy) from the grid or a power plant and then discharges that energy at a later time to provide electricity or other grid services when needed. Several battery chemistries are available or under investigation for grid-scale applications, including ...

Housed in a giant warehouse, the 1,300-metric ton battery is larger than a football field, and can crank out 40 million watts of power. Still, the Fairbanks battery provides only enough electricity for about 12,000 residents for seven minutes. That was enough to prevent 81 blackouts in the city in the battery''s first two years of operation.

PSH acts similarly to a giant battery, because it can store power and then release it when needed. The Department of Energy''s "Pumped Storage Hydropower" video explains how pumped storage works. The first known use cases of PSH were found in Italy and Switzerland in the 1890s, and PSH was first used in the United States in 1930.
