How gravity batteries will help us switch to renewable energy
Gravity batteries might be the answer. The idea sounds simple – when there is plenty of green energy, the batteries use the power to lift a heavy weight either high into the air or to the top of a deep shaft. Then when the power is needed, winches gradually lower the weight, and produce electricity from the movement of the cables.
What is renewable energy storage?
Pumped-storage hydroelectricity is a type of gravity storage, since the water is released from a higher elevation to produce energy. Flywheel energy storage To avoid energy losses, the wheels are kept in a frictionless vacuum by a magnetic field, allowing the spinning to be managed in a way that creates electricity when required.
