Rolls-Royce has achieved a significant milestone by obtaining a H2 readiness certification from TÜV Süd for its mtu Series 4000 FNER/FV gas engines, certifying them for hydrogen use up to 25% by volume and 100% hydrogen. This certification ensures that Rolls-Royce's engines can operate in a CO2-free manner when using green hydrogen, meeting strict emission limits without exhaust gas aftertreatment. The company's focus on sustainable fuels and lower carbon emissions aligns with its strategic pillar, leading to this certification. The first installation of mtu engines running on 100% hydrogen is planned for a CO2-neutral energy supply project in Duisburg, Germany, providing a glimpse into the future of hydrogen-powered energy solutions. Rolls-Royce is actively developing next-generation hydrogen engines in collaboration with partners to achieve high efficiency and comparable performance to natural gas units, supporting the energy transition towards renewable energy sources. This progress highlights Rolls-Royce's commitment to innovation and sustainability in the energy sector, paving the way for a greener future with hydrogen technology.
