Pumped storage hydropower is a form of clean energy storage that is ideal for electricity grids reliant on solar and wind power. It absorbs surplus energy at times of low demand and releases it when demand is high.
These technologies work like giant batteries by storing renewable energy and releasing it onto the grid and into homes when needed. This includes pumped storage hydro, which stores electricity by pumping water up a reservoir, to be released later.
You can store electricity in electrical batteries, or convert it into heat and stored in a heat battery. You can also store heat in thermal storage, such as a hot water cylinder. Energy storage can be useful if you already generate your own renewable energy, as it lets you use more of your low carbon energy.
