Thermal energy can be stored by simply changing the temperature of a material to higher level for heat storage or to lower level for cold storage. The amount of the stored energy can be calculated as the product of the specific heat capacity, the mass of the used material and the temperature difference.

Focus We are all familiar with small-scale electrical energy storage in chemical batteries, from cars to cell phones. Batteries offer near-instant response time, but cost tends to scale linearly with size, making very large batteries or

Pumped storage stores electricity in the form of potential energy. The basic principle of energy conversion is shown in Fig. 1.
