Rolls-Royce successfully carried out initial tests of the world’s first high-speed marine engine powered exclusively by pure methanol. This is an important step toward reducing carbon emissions in shipping. Today, about 90% of global trade is carried by sea, and almost the entire fleet runs on diesel fuel, generating more than 3% of global greenhouse gas emissions.
Methanol, especially when produced from renewable sources, is considered a clean fuel: it emits fewer harmful compounds, does not produce soot, and is easy to store. However, using it required engineers to redesign the entire combustion and fuel injection system. Particular attention was given to compatibility with existing marine installations. A hybrid version is also planned.
Interest in methanol in shipping is growing rapidly — according to Maersk, by 2040 it could become the industry’s main fuel. However, solutions capable of replacing diesel at high speeds had been unavailable. Rolls-Royce is opening up a real possibility for the environmental modernization of the marine fleet while maintaining the required levels of power and reliability.
