How Energy Storage Works | Union of Concerned Scientists
Simply put, energy storage is the ability to capture energy at one time for use at a later time. Storage devices can save energy in many forms (e.g., chemical, kinetic, or thermal) and convert them back to useful forms of energy like electricity. Although almost all current energy storage capacity is in the form of pumped hydro and the ...
