Thermal energy grid storage: Liquid containment and pumping above
Excess electricity (left) is converted to heat and stored at a peak temperature above 2000 °C until needed. Then, it is pumped through a multi-junction photovoltaic (MPV) heat engine, where electricity is produced. The fluid (nominally 500 °C colder than the hot tank) is then stored until excess electricity is available again.
