olls-Royce and cellcentric, a joint venture company set up by Daimler Truck AG and Volvo Group AB, are taking the next step in their strategic cooperation for the deployment of cellcentric hydrogen fuel cell modules. Rolls-Royce, through its Power Systems business unit, is to develop complete mtu hydrogen fuel cell solutions based on cellcentric’s fuel cell modules which emit nothing other than water vapour. This will enable C02-free, climate-neutral generation of emergency power for data centers. Rolls-Royce is among the world's top three suppliers of emergency gensets for data centers. Both Rolls-Royce and cellcentric are keen to play a part in driving the fuel cell breakthrough and are convinced that the technology – and time – are right for successfully launching commercial fuel cell applications for the mass market.
