Are flywheels the future of energy storage?

Global decarbonisation requires green energy storage solutions, of which flywheels have been touted as one of its principal proponents. These clever yet simple mechanical systems are certainly part of the energy storage future, just perhaps not in the way you envisage. Read on to find out why! Contents What is a flywheel?

How does a flywheel store energy?

(Credit: Flywheel) Flywheels store rotational energy using the physical principle of conservation of angular momentum. In plain English, a flywheel is a heavy wheel that stores energy by rotating efficiently. The heavier this rotating wheel, and the less resistance it experiences, the more energy it can store for longer periods of time.
