Energy Storage

Flywheel powered trams can be particularly convenient in cities for they dispense with overhead electrification. Notwithstanding this fact, today there''s only one commercial case to refer, in the Stourbridge line in London. Flywheel energy storage systems using mechanical bearings can lose 20% to 50% of their energy in 2 hours.[27]
