As the world looks to limit greenhouse gas emissions, carbon-free renewable energy sources such as solar and wind will play a growing role on power grids. But such sources cannot generate electricity all the time. According to David L. Trumper, professor of mechanical engineering, a good way to smooth out supply would be using a

Energy storage is the capture of energy produced at one time for use at a later time [1] to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential
