Answer for ZeUS project

The Mayor

Transport for London (TfL) is a partner in the European funded project ZeEUS (Zero Emission Urban Bus System), which started at the end of 2013. ZeEUS is testing innovative electric bus technologies with different charging infrastructure solutions in ten demonstration sites across Europe, including London. TfL is testing a high-power wireless charging system, installed at Canning Town and Walthamstow bus stations at either end of route 69. Three specially-built range-extended double deck buses use induction charging to top up their batteries during the layover at each end of the route. The batteries have a larger capacity than those in existing hybrid buses, and enable the ZeEUS buses to operate mostly in electric mode.

The buses on route 69 were progressively introduced into service and the charging infrastructure fully commissioned during 2016. With over a year of monitoring data, the three buses operated over 50 per cent of service using grid electricity from the wireless chargers. By ensuring these buses run out of the depot in the morning fully charged by plugging in overnight, it is possible to deliver over 80 per cent of the route 69 bus service with electricity from the grid. While the ZeEUS project will formally conclude in spring 2018, TfL intends to continue to operate the three buses and charging equipment for the foreseeable future.
