UK-based global major power and propulsion systems group Rolls-Royce has announced that its Germany-based Power Systems division has commissioned its first in-house test stand for hydrogen-powered gas turbine engines. The division produces these engines under the ‘mtu’ brand. The test stand is located at the company’s site in Augsburg, in the German ‘Land’ (State) of Bavaria. The setting-up of the test stand, its associated hydrogen infrastructure and environmental protection measures, cost €10-million, over the past 18 months.
