Technology

Kinetic Traction Systems' main product uses flywheel energy storage technology developed by Pentadyne Power Corp; staff from Pentadyne joined Kinetic.[2] The 36000 RPM flywheels are originally based on uranium centrifuge technology developed by Urenco[3]

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.[4]

Their grid storage system helps stabilise the microgrid on the island of Eigg[5]

Capacity

Usable stored energy is approximately 6 megajoules (1.7 kWh).[6] The devices can provide bursts of 200 kilowatt-hours (720 MJ).[7]
