How do you store light as energy?

Re your next question storing light as light seems a pointless exercise. We don't store electricity as charge, we store it as chemical energy in a battery because that's easier, cheaper and more useful. If you want to store light put the energy in a battery then use the energy to power an LED.

Why is energy storage important in a decarbonized energy system?

Credit: Shutterstock In deeply decarbonized energy systems utilizing high penetrations of variable renewable energy (VRE), energy storage is needed to keep the lights on and the electricity flowing when the sun isn’t shining and the wind isn’t blowing—when generation from these VRE resources is low or demand is high.

Why do we need energy storage facilities?

The increasing integration of renewable energy sources into the electricity sector for decarbonization purposes necessitates effective energy storage facilities, which can separate energy supply and demand.

Why is it hard to store light as light?

It's hard to store light as light because the most common way light interacts with matter is through absorption and emission, which is how mirrors work. However light rays can be bent by gravity, so it would be possible to arrange several massive stars in a way such that a light ray would move in a loop around the stars without energy loss.

Can storage facilities transform the power generation sector?

Therefore, the authors concentrate on Lithium BESS. The study highlights the crucial role of storage facilities in transforming the power generation sector by shifting toward renewable sources of energy.

How do you store electricity as a charge?

We don't store electricity as charge, we store it as chemical energy in a battery because that's easier, cheaper and more useful. If you want to store light put the energy in a battery then use the energy to power an LED. @raptortech97: we can store charge temporarily in a capacitor and we can store a magnetic field temporarily in an inductor.
