Everllence has unveiled its new dual-fuel ME-LGIA engine, designed to run on ammonia, at a two-day event in Copenhagen attended by over 300 maritime industry professionals. The engine, which uses the Diesel principle and the dual-fuel Liquid Gas Injection concept, is the latest addition to Everllence’s lineup of green engines, joining the ME-LGIM and ME-LGIP units that run on methanol and LPG, respectively.
The ME-LGIA engine is equipped with additional safety features to handle ammonia’s unique characteristics, including containment systems, sensors, system ventilation, and double-walled piping. Dr Uwe Lauber, CEO of Everllence, emphasized the importance of ammonia in the maritime industry’s transition to zero-carbon shipping. “As the maritime industry’s leading engine designer, we are in a unique position to advance the green transition and know that bringing new fuels to market is not just innovation – it’s imperative for zero-carbon shipping. In this context, ammonia is a vital piece of the puzzle. The development of this engine is not just a technical achievement; it is another concrete step towards a climate-neutral future where the time to act is now.”
The first ME-LGIA engine is scheduled for delivery in Q1 2026, with bedding-in set for Q4 2025. Everllence is currently involved in several pilot projects, including two Very Large Ammonia Carriers for Eastern Pacific Shipping, four engines for Höegh Autoliner Pure Car and Truck Carriers, and one for a bulk carrier in Japan, where the engine is currently on the MITSUI E&S testbed.
Bjarne Foldager, Head of Two-Stroke Business at Everllence, highlighted the extensive testing and development process behind the ME-LGIA engine. “This ammonia engine is truly a technological milestone. It is the result of over 150,000 hours of collective work and represents a significant financial investment on our part. Since two-stroke engine testing on ammonia started in July 2023, we have carried out over 800 tests – both here in Copenhagen and at MITSUI E&S in Japan. All the way through, safety has been our first consideration and we have worked closely with the relevant authorities and classification societies to ensure that the technology meets all demands. Combined with the knowledge we will gather from the pilot-projects, we are confident that this responsible approach will ultimately deliver the market gold-standard in ammonia engines with a final design based on operational experience.”
The ME-LGIA engine is also designed to be digitally connected, enabling a secure and reliable data flow from vessels to Everllence’s shore-based monitoring. This real-time data can be used to improve performance, provide remote assistance, and help shipowners operate more efficiently and sustainably. Data-driven insights will play a significant role in supporting decarbonisation as new fuels like ammonia enter the market.
Everllence plans to initially offer the ME-LGIA engine in G50, S50, S60, G60, G70, and G80 bore sizes, with retrofit options to be made available eventually. This new engine represents a significant step forward in the maritime industry’s efforts to reduce emissions and transition to a more sustainable future.
