Rolls-Royce is making significant strides in hydrogen engine technology, particularly in Germany. The company has received H2 readiness certification for its mtu Series 4000 FNER/FV gas engines from TÜV Süd, enabling future use with hydrogen. Dr. Jörg Stratmann, CEO of Rolls-Royce Power Systems, emphasizes the importance of hydrogen in the energy transition. The company plans to offer engines that can operate with hydrogen admixtures ranging from 25% to 100% by volume. This move aims to promote the use of sustainable fuels and contribute to the success of the energy transition. Additionally, Rolls-Royce is part of a consortium working on developing efficient hydrogen combustion engines for combined heat and power plants. The upcoming hydrogen engine from this collaboration is expected to match the performance of natural gas units. The Enerport II lighthouse project in Duisburg is set to showcase the first installation of mtu engines running on 100% hydrogen, aiding in CO2-neutral energy supply. Rolls-Royce's commitment to hydrogen technology is evident in their testing facilities in Augsburg and Friedrichshafen, where engineers are currently testing the engines for the Enerport II project. With promising results from the mtu Series 4000 L64 gas engine, Rolls-Royce is on track to meet the project's energy output goals. Rolls-Royce's dedication to green technology and efficient hydrogen engines signifies a positive step towards sustainable energy solutions.
