Giant flywheels are to be installed around the UK to minimise the risk of blackouts as the power system goes carbon-free.
Flywheels are energy storage systems that use surplus electricity to accelerate a massive metal “wheel”, thereby turning it into mechanical energy. To avoid energy losses, the wheels are kept in a frictionless vacuum.
If the grid needs a boost of electrical energy, the spinning disk can be used to generate power via magnetic induction – just as happens in the steam turbines of a traditional power station.
It follows warnings that the removal of coal, gas and nuclear power stations from the system will leave the grid without the secure steady baseload needed to maintain stability. https://www.telegraph.co.uk/…/giant-flywheels-to-be…/
