Energy storage

Energy storage is useful when energy is harvested at a different time from when it's used. For example, electricity must be used very quickly after it's been made (within milliseconds). Energy storage would be needed if the electrical grid starts relying on large amounts of intermittent electricity sources like wind power. Below is a list of the different types of energy storage that have been proposed. Click the links below to learn more about each type of energy storage.
