Ballard Power Systems has announced the recent signing of an agreement between Van Hool NV, Europe's fourth largest bus manufacturer, and the Transit Authority in Aberdeen, Scotland for delivery of 10 buses that will be powered by Ballard's 150 kilowatt FCvelocityTM-HD6 fuel cell module.

Ballard Power Systems has announced the recent signing of an agreement between Van Hool NV, Europe's fourth largest bus manufacturer, and the Transit Authority in Aberdeen, Scotland for delivery of 10 buses that will be powered by Ballard's 150 kilowatt FCvelocityTM-HD6 fuel cell module.

When deployed in revenue service, the 10-bus fleet to be operated in Aberdeen will be Europe's largest hydrogen fuel cell bus fleet. Furthermore, by early-2014 approximately 40 buses in Europe will be powered by Ballard fuel cell modules.

In December 2011, Ballard announced an equipment supply agreement (ESA) with Van Hool for 21 of the Company's latest-generation 150 kilowatt FCvelocityTM-HD6 modules, with an expectation that the majority of these would be shipped in 2012. By the end of 2012, 14 modules had been shipped to Van Hool. These will be used in 5 buses to be deployed in San Remo, Italy, 5 buses to be deployed in Flanders, Belgium as well as 4 of the buses to be deployed in Aberdeen. All these deployments are being supported by European Joint Technology Initiative (JTI) funding through the High V.LO-City program.

Through the remainder of 2013 Ballard expects to ship a further 8 power modules to Van Hool, including 6 to be used in the Aberdeen deployment and 2 for use in buses to be deployed in Cologne, Germany. The Cologne buses are being procured by the government of North Rhine Westphalia (NRW), with funding support from the German National Innovation Program. The Aberdeen buses are being supported by JTI funding through the High V.LO-City and HyTransit programs. This will bring the total number of modules shipped to Van Hool to 22 since December 2011.

Ballard's sixth generation FCvelocityTM-HD6 fuel cell module features a control unit which interfaces with a system controller to make it a "plug-and-play" product for any fuel cell or hybrid fuel cell bus platform. The module also offers significant advances in durability, power density and fuel efficiency compared to earlier generation products.

Increased volumes of fuel cell-powered buses are supporting cost and price reductions through scale of economies, enabling fuel cell solutions to compete more effectively with incumbent transit technologies.
