Rolls-Royce tests world’s first marine engine powered by 100% methanol

Rolls-Royce has successfully tested the world’s first high-speed marine engine powered entirely by methanol, marking a significant advancement in sustainable ship propulsion. Conducted at Rolls-Royce Power Systems in Germany as part of the meOHmare research project, this milestone involved collaboration with fuel injection specialist Woodward L’Orange and research institute WTZ Roßlau, funded by the German Federal Ministry for Economic Affairs and Energy. The engine is designed specifically for vessels such as ferries, yachts, and supply ships, aiming to reduce carbon emissions by utilizing green methanol produced via renewable energy. Rolls-Royce engineers had to redesign key components including the combustion process and turbocharging system to accommodate methanol’s unique properties. Methanol is highlighted as a promising marine fuel due to its near CO2-neutral lifecycle when produced sustainably, biodegradability, ease of storage, and lower pollutant emissions compared to traditional fossil fuels. Rolls-Royce views this development as a crucial step toward decarbon
