New hybrid flywheel helps power stations utilise renewable energy

A new design of hybrid flywheel energy system developed in Ireland will help power stations balance demand and integrate renewable power sources.

The system uses a novel motor-generated flywheel to harness kinetic energy from the grid at times of over-supply. This is then released from submerged turbines at times of supply shortfalls.

In the flywheel system, advanced carbon fibre tubes up to 3m high and 1m wide are floated on magnets inside a vacuum. The hybrid powered flywheel system can in a near frictionless environment rapidly absorb short-term excess gird energy and generate energy as needed by grid operators.

The Schwungrad Energie flywheel project has received funding from the European Commission and the Irish government
