100mw flywheel energy storage

Can flywheel energy storage be commercially viable?

This project explored flywheel energy storage R&D to reach commercial viability for utility scale energy storage. This required advancing the design, manufacturing capability, system cost, storage capacity, efficiency, reliability, safety, and system level operation of flywheel energy storage technology.

What is a flywheel energy storage system?

Flywheel energy storage systems are widely used in space, hybrid vehicles, military field, and power quality applications. In these fields, they function as energy storage and attitude control systems. Space stations, satellites, and aircraft are the main application fields in space.

Can flywheel energy storage be used in secondary frequency regulation?

The Shandong company's flywheel energy storage project, designated as a demonstration project by the National Energy Administration, aims to explore the potential of flywheel storage technology in secondary frequency regulation for Automatic Generation Control (AGC).

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.
