Carbon fiber flywheel for London buses
The Go-Ahead Group and GKN plc have agreed a deal that will help reduce emissions in cities with the supply of electric flywheel systems to 500 buses over the next two years.
The innovative GKN system is based on Formula One race technology developed in the UK. It will help increase the efficiency of every bus to which it is fitted by using less fuel and therefore reducing carbon emissions. This same technology helped Audi’s R18 e-tron win at Le Mans last month.
Go-Ahead has placed an order for GKN Hybrid Power to supply 500 of its Gyrodrive systems to the transport operator. The Gyrodrive system uses a high speed flywheel made of carbon fibre to store the energy generated by a bus as it slows down to stop. It then uses the stored energy to power an electric motor which helps accelerate the bus back up to speed, generating fuel savings of more than 20% at a significantly lower cost than battery hybrid alternatives.
