Kinetic Traction Systems is a business founded in November 2010, producing Flywheel energy storage systems for electric railways and grid storage.
Technology.
Kinetic Traction Systems' main product uses flywheel energy storage technology developed by Pentadyne Power Corp; staff from Pentadyne joined Kinetic. The 36000 RPM flywheels are originally based on uranium centrifuge technology developed by Urenco
KTS' rail-side device uses a brushless DC motor/generator to spin up the flywheel to store electrical energy (for instance, from regenerative braking on trains) as kinetic energy; later to be converted back to electrical energy on demand.
Uses.
This system allows significant energy-efficiency improvements in urban rail systems; it has been used by NYC Transit and the London Underground.
Their grid storage system helps stabilise the microgrid on the island of Eigg
Capacity.
Usable stored energy is approximately . The devices can provide bursts of .
