Flywheels are an economic solution for meeting the growing need for electrical energy storage
In this article from the European Energy Centre, Professor Keith Pullen from City University of London discusses the use of flywheels as an ‘effective and sustainable’ way to meet the growing demand for energy storage.
As Dr Pullen explains, the increased use of renewable energy is creating supply and demand problems, since energy creation is often dependent on variables, such as seasons and weather. In order to counter this problem, energy storage will be crucial.
Although Lithium Ion batteries are providing one solution, they can have quite short lives and degrade very quickly. There are also plans to use EV batteries but, as with Lithium Ion batteries, these will degrade and will need to be disposed of.
A flywheel stores energy in rotational momentum and could be an excellent way to ensure that we are able to store energy produced from renewable sources for use when required, says Dr Pullen.
