What is a flywheel energy storage system (fess)?
The technology is referred to as a flywheel energy storage system (FESS). The amount of energy stored is proportional to the mass of the rotor, the square of its rotational speed and the square of its radius. Flywheel energy storage consists in storing kinetic energy via the rotation of a heavy object. Find out how it works.
What are the advantages of flywheel ESS (fess)?
Flywheel energy storage systems (FESS) have several advantages, including being eco-friendly, storing energy up to megajoules (MJ), high power density, longer life cycle, higher rate of charge and discharge cycle, and greater efficiency.
How can flywheels be more competitive to batteries?
The use of new materials and compact designs will increase the specific energy and energy density to make flywheels more competitive to batteries. Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel’s secondary functionality apart from energy storage.
