British luxury car manufacturer Rolls-Royce has successfully tested the world's first pure methanol marine engine for clean ship propulsion.
British luxury car maker Rolls-Royce has successfully tested the world’s first high-speed marine engine running purely on methanol to transform ship propulsion and cut carbon emissions across the maritime industry.
The test was carried out at Rolls-Royce Power Systems, the company’s advanced engineering division based in Friedrichshafen, Germany, as part of the meOHmare research project. The collaboration includes fuel injection specialist Woodward L’Orange GmbH from Feuerbach, Germany, and research institute WTZ Roßlau, specializing in engine technology, fuel systems, and alternative propulsion solutions.Funded by the German Federal Ministry for Economic Affairs and Energy, the initiative aims to develop a comprehensive, CO2-neutral, high-speed engine concept by the end of 2025, based entirely on green methanol.“This is a genuine world first,” Jörg Stratmann, PhD, CEO of Rolls-Royce Power Systems AG, pointed out. “To date, there is no other high-speed engine in this performance class that runs purely on methanol.”Reshaping ship propulsionIn contrast to diesel, methanol is a colorless liquid alcohol that doesn’t ignite on its own and requires an entirely new injection system. Because of that, Rolls-Royce engineers completely redesigned the combustion process, turbocharging system, and engine controls.They even reconfigured the test bench infrastructure to handle the demands of methanol fuel. “Initial tests show that the engine is running smoothly – now it’s time for fine-tuning,” Johannes Kech, Rolls-Royce’s head of methanol engine development within the power systems division, elaborated.Rolls-Royce is testing the first pure methanol marine engine in the meOHmare research project with its partners Woodward L’Orange and WTZ Roßlau.Credit: Rolls-RoyceMethanol has emerged as one of the most promising fuels for decarbonizing maritime transport. This is because it offers nearly CO2-neutral operation when produced using renewable energy through power-to-X technology.It’s biodegradable, easy to store, and produces significantly fewer pollutants than fossil fuels. All of these qualities make it ideal for ferries, yachts and offshore vessels aiming to meet tightening environmental standards.“We are investing specifically in future technologies to open up efficient ways for our customers to reduce CO2 emissions and further expand our leading role in sustainable propulsion systems,” Stratmann stated.A cleaner futureAs per Denise Kurtulus, Rolls-Royce’s senior vice president of global marine, the successful test marks a turning point for sustainable shipping. She believes it also proves that green methanol is a forward-looking fuel and that the technology to support it already exists.“The single-fuel methanol engine is an attractive solution, especially for operators of ferries, yachts, or supply vessels who want to reduce their carbon footprint,” Kurtulus said. “The task now is to create the framework conditions for wider use.”The company revealed that the new engine’s development aligns with its strategy to expand its marine portfolio with lower-carbon technologies. It is also working on a dual-fuel concept that can use both methanol and diesel, as a transitional technology while supply chains for green methanol become widely available.“For us, methanol is the fuel of the future in shipping – clean, efficient, and climate-friendly,” Kurtulus concluded in a press release. “It burns with significantly lower emissions than fossil fuels and has a high energy density compared to other sustainable energy sources.”
