Could flywheels be the future of energy storage?
Flywheels, one of the earliest forms of energy storage, could play a significant role in the transformation of the electrical power system into one that is fully sustainable yet low cost.
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.
How do electrical flywheels work?
Electrical flywheels are kept spinning at a desired state of charge, and a more useful measure of performance is standby power loss, as opposed to rundown time. Standby power loss can be minimized by means of a good bearing system, a low electromagnetic drag MG, and internal vacuum for low aerodynamic drag.
