Rolls-Royce is further developing its mtu gas engine portfolio for power generation and cogeneration to run on hydrogen as a fuel and thus enable a climate-neutral energy supply. Already, gensets powered by mtu Series 500 and Series 4000 gas engines can be operated with a gas blending of 10% hydrogen. Beginning in 2022, operation with a hydrogen content of 25% will be possible. Rolls-Royce builds expertise for H2 ecosystem: In addition, fuel cells powered by 100% green hydrogen can play an important role in future energy supply in combination with renewable energies. At its Friedrichshafen headquarters, Rolls-Royce's Power Systems division has installed a 250-kilowatt fuel cell demonstrator, which will be used to test and present future CO2-free energy systems to customers. The entire hydrogen ecosystem, including the infrastructure for supply, conversion, test benches and future production, is also being mapped in the company's own plants, thus building up expertise.
