fuel cell, any of a class of devices that convert the chemical energy of a fuel directly into electricity by electrochemical reactions.A fuel cell resembles a battery in many respects, but it can supply electrical energy over a much longer period of time. This is because a fuel cell is continuously supplied with fuel and air (or oxygen) from an

A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.

Energy storage system (ESS) is playing a vital role in power system operations for smoothing the intermittency of renewable energy generation and enhancing the system stability. We divide ESS technologies into five categories, mainly covering their development history, performance characteristics, and advanced materials.

The electrical energy storage technologies are grouped into six categories in the light of the forms of the stored energy: potential mechanical, chemical, thermal, kinetic mechanical, electrochemical, and electric-magnetic field storage. The technologies can be also classified into two families: power storage and energy storage.

Thermal Energy Storage. In thermodynamics, internal energy (also called the thermal energy) is defined as the energy associated with microscopic forms of energy. It is an extensive quantity, it depends on the size of the system, or on the amount of substance it contains. The SI unit of internal energy is the joule (J).

Thus to account for these intermittencies and to ensure a proper balance between energy generation and demand, energy storage systems (ESSs) are regarded as the most realistic and effective choice, which has great potential to optimise energy
