What is a Flywheel Storage Power System?
A flywheel-storage power system uses a flywheel for grid energy storage, and can be a comparatively small storage facility with a peak power of up to 20 MW. It typically is used to stabilize power grids, helping them stay on the grid frequency, and to serve as a short-term compensation storage.
Background Context
Energy storage systems are becoming increasingly important as the world transitions to renewable energy sources. Traditional power plants, such as pumped storage power plants, can store large amounts of energy, but they often require significant infrastructure and can be expensive to build. Flywheel storage power systems, on the other hand, offer a more compact and cost-effective solution for short-term energy storage.
How Does it Work?
Flywheel storage power systems consist of individual flywheels in a modular design. Energy up to 150 kWh can be absorbed or released per flywheel. Through combinations of several such flywheel accumulators, which are individually housed in buried underground vacuum tanks, a total power of up to several tens of MWh can be achieved.
Benefits and Applications
Flywheel storage power systems are comparable to battery storage power plants in their application. They are particularly useful in places where electrical energy can be obtained and stored, and must be supplied again to compensate for fluctuations in the seconds range in wind or solar power.
Combination with Battery Storage Power Stations
Sometimes, battery storage power stations are built with flywheel storage power systems in order to conserve battery power. Flywheels can handle rapid fluctuations better, making them a useful addition to battery-based energy storage systems.
