What are Flywheel Energy Storage Systems?

Flywheel Energy Storage Systems are interesting solutions for energy storage, featuring advantageous characteristics when compared to other technologies. Research focuses on cost aspects, system reliability, and energy density improvement for these systems. In this context, a novel shaftless outer-rotor layout is proposed.

How much energy does a flywheel store?

It would probably have to be in a cement enclosure, and in Florida a sump pump to keep it dry. A 1,000kg, 5m, 200RPM flywheel would store 685,567J of energy if it was shaped like a disc. That's 0.19kWh of energy — enough to boil the water for about seven (7) cups of tea or run a typical airconditioner for about 10 minutes.

How much energy does a flywheel lose in 2 hours?

Flywheel energy storage systems using mechanical bearings can lose 20% to 50% of their energy in two hours. Much of the friction responsible for this energy loss results from the flywheel changing orientation due to the rotation of the earth ....

How does a generator flywheel work?

Generator flywheel and diesel were on one axis with a coupling towards the diesel. The flywheel was constructed as an engine around that axis, so the stator is the axis at 1500 rpm and the flywheel turns around at max. 4400 rpm. If energy needs to be provided, the outer rotor is slowed down by a brake in that axis, so the energy is transferred

Do you need a vacuum chamber for a flywheel storage system?

Magnetic bearings and a vacuum sealed chamber are the must. I'm not getting in the argument about a true vacuum but it's sealed in a vacuum housing. They have several commercial flywheel storage systems up and running in the United States. And yes, when it goes bad, it's instantaneous.

What are the advantages of magnetic bearings in flywheel energy storage?

You must log in or register to reply here. Flywheel Energy Storage Flywheels with magnetic bearings are 97% efficient, have an 85% round trip efficiency, are not adversely affected by temperature, have high C-Rates, zero degradation (do not degrade over time based on DoD or C-Rate), unlimited cycling, are made of inert/benign materials...
