The rotor is attached to the rod, towards the bottom, and the stator is on the ground directly below the rod. The flywheel is a few centimeters above the rotor.
In order to eradicate any energy loss due to friction, the flywheel is placed inside a vacuum containment. It is also suspended by bearings so that operation is stable.
Flywheel energy storage systems provide power stations with a robust solution for grid stabilization, renewable integration, and operational cost reduction.
The system is designed to allow siting and operation at any size from 100 kW to multi-MW power blocks. This modular configuration minimizes site footprint and enables owners to place the exact amount of stabilizing resource in the exact location needed.
The project will install climate-adapted floating solar photovoltaic (FPV), a battery energy storage system (BESS), a transmission and distribution network, productive uses of energy (PUE), such as electric vehicles (EVs) including an e-boat for the operation and.
Another significant project is the installation of a flywheel energy storage system by Red Eléctrica de España (the transmission system operator (TSO) of Spain) in the Mácher 66 kV substation, located in the municipality of Tías on Lanzarote (Canary Islands).
The Dinglun Flywheel Energy Storage Power Station, with a capacity of 30 MW, is now the world's largest flywheel energy storage project which is operational, surpassing previous records set by similar projects in the United States.
The energy storage project is expected to be in operation by the end of 2025. This research and development will improve manufacturability and scalability of sodium-ion batteries, flow batteries, and nanolayered films for energy storage.
