Energy storage systems let you capture heat or electricity when it's readily available,. This kind of readily available energy is typically renewable energy. By storing it to use later, you make more use of renewable energy sources and are less reliant on fossil fuels. Let's look at how they work and what the different types of energy storage are.
Energy storage can be useful if you already generate your own renewable energy, as it lets you use more of your low carbon energy. It reduces wasted energy and is more cost effective than exporting excess electricity. For example, you can store electricity generated during the day by solar panels in an electric battery.
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.
Pumped storage hydropower (PSH) is a form of clean energy storage that is ideal for electricity grid reliability and stability. PSH complements wind and solar by storing the excess electricity they create and providing the backup for when the wind isn't blowing, and the sun isn't shining.
