Rolls-Royce’s successful test of the world’s first high-speed marine engine powered purely by methanol is a pivotal step towards climate-neutral shipping, specifically targeting smaller vessels like ferries, yachts, and supply boats.
World-First Engine Development
Rolls-Royce achieved this milestone at its test bench in Friedrichshafen as part of the meOHmare research project.
- Engine Type: It is the first high-speed engine in its performance class to run exclusively on methanol, demonstrating the viability of this new propulsion system.
- Goal: The project, funded by the German Federal Ministry for Economic Affairs and Energy, aims to develop a comprehensive concept for a CO2-neutral marine engine based on green methanol by the end of 2025.
- Partners: The meOHmare consortium includes Rolls-Royce, fuel injection specialist Woodward L’Orange, and the WTZ Roßlau technology and research center.
The Role of Methanol in Decarbonization
Methanol is emerging as one of the most promising alternative marine fuels for achieving the industry’s reduction goals.
- Green Methanol: When produced using renewable electricity in a power-to-X process, it offers CO2-neutral operation because the CO2 released during combustion is balanced by the CO2 captured during its production.
- Environmental Benefits: It burns with significantly lower emissions of sulfur, nitrogen oxides, and particulates compared to fossil fuels. It is also biodegradable and less explosive than alternatives like LNG or hydrogen.
- Logistical Advantages: Methanol is liquid at ambient temperatures, making it easier to store and handle using existing infrastructure, unlike fuels that require cryogenic temperatures.
