Abstract

This paper describes the authors’ investigation into deploying durable, low cost electric flywheel technology on rail vehicles by means of simulation. Diesel engines currently power trains on non-electrified lines, over half the UK rail network, so the Rail Safety and Standards Board (RSSB) commissioned research to devise efficiency improvements. Substantial benefits in the form of diesel traction energy saving and braking energy recovery were calculated, amounting to 43% for regional passenger services. Further, the flywheel technology is traction-type independent: it could be key to unlocking discontinuous electrification or to improve the effectiveness of any prime mover. A follow-on hardware demonstration project has just commenced.
