Rolls-Royce has achieved an important milestone by receiving H2 readiness certification for its current MTU Series 4000 FNER/FV gas engines, indicating its preparedness to produce 100% hydrogen engines. This certification, granted by TÜV Süd, ensures that the engines' components and systems are ready for future use with hydrogen and can be converted accordingly. The company's commitment to reducing carbon emissions is further evidenced by this step towards utilizing hydrogen as a fuel source. Rolls-Royce plans to increase investment security for its customers by enabling the use of hydrogen with its engines in the future. At the recent Powergen Symposium, the company announced the new certification, which covers both newly built and retrofitted power plants using these engines, allowing for a hydrogen admixture of up to 25% by volume and potential full conversion to 100% hydrogen. In addition to the certification, Rolls-Royce is working on a hydrogen-powered jet engine and is set to deliver its first 100% hydrogen combined heat and power (CHP) engine in the coming months. The company aims to install MTU engines running on 100% hydrogen for the Enerport II lighthouse project in Duisburg, Germany, by early 2025. Tests have indicated excellent performance, efficiency, and emission characteristics of the 12-cylinder MTU Series 4000 L64 gas engine, achieving the desired total output of one megawatt and expecting further development to reach 1.2 megawatts. Rolls-Royce emphasizes that when using 'green hydrogen', their engines become completely CO2-free, aligning with sustainability goals. Dr. Jörg Stratmann, CEO of Rolls-Royce Power Systems, views hydrogen as a crucial element in the energy transition and highlights the company's commitment to sustainable fuels and contributing to the success of the transition.
