Rolls-Royce has achieved a significant milestone by obtaining hydrogen compatibility certification for its mtu 4000 Series FNER/FV gas engines from TÜV Süd. This certification allows the engines to run on a hydrogen mixture of up to 25%, positioning them as environmentally friendly options. The company has announced plans to deliver the first megawatt from a 100% hydrogen mtu engine in the near future, highlighting its commitment to reducing carbon emissions. By utilizing green hydrogen, these engines will operate without CO2 emissions, aligning with stringent EU regulations without the need for exhaust gas treatment. The first initiative to incorporate 100% hydrogen engines is scheduled for 2025 in Duisburg, Germany, showcasing the practical application of hydrogen technology. Moreover, Rolls-Royce is focusing on developing advanced hydrogen engines capable of generating energy levels equivalent to current natural gas engines, signaling a promising future for sustainable engine technology.
