Critical review of energy storage systems

As of 2018, the energy storage system is still gradually increasing, with a total installed grid capacity of 175 823 MW [ 30 ]. The pumped hydro storage systems were 169557 GW, and this was nearly 96% of the installed energy storage capacity worldwide. All others combined increased approximately by 4%.

Thermoelectric cooling

Thermoelectric cooling uses the Peltier effect to create a heat flux at the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current.
