France-headquartered mega-utility EDF has accepted delivery and installation of a flywheel energy storage system manufactured by Germany’s Stornetic, at EDF’s “full testing playground” south of Paris.

German firm talks up its flywheel energy storage system as a solution for wind farms and public transport.

German manufacturer Stornetic is to make its flywheel storage system available to train operators, so they can store energy from braking trains at stations to help power them as they depart again.
