New B&W ME-LGIA ammonia dual-fuel engine sets new benchmark in zero-carbon propulsion and digitally-connected performance \u2013 now open for newbuilding orders<\/p>\n
Thursday, November 13, 2025<\/p>\n
At a two-day event in Copenhagen with over 300 attendees representing all sectors of the maritime industry,\u00a0Everllence\u00a0has unveiled its new, dual-fuel ME-LGIA (-Liquid Gas Injection Ammonia) engine.<\/p>\n
Using the Diesel principle and the well-known, dual-fuel Liquid Gas Injection concept, the ME-LGIA engine has many of the same merits as\u00a0Everllence\u2019s\u00a0existing ME-LGIM and ME-LGIP units that, respectively, run on methanol and LPG. However, in light of ammonia\u2019s particular characteristics, the new engine also has additional safety features such as containment systems, sensors, system ventilation and double-walled piping developed especially for ammonia as a fuel.<\/p>\n
Dr Uwe Lauber, CEO\u00a0Everllence<\/strong>, said: \u201cAs the maritime industry\u2019s 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\u00a0\u2013 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.<\/em>\u201d<\/p>\n Everllence\u00a0reports that the first ME-LGIA engine is due for delivery in Q1, 2026 with bedding-in set for Q4, 2025. The company is currently engaged in several pilot-projects, including 2\u00a0\u00d7 Very Large Ammonia Carriers for Eastern Pacific Shipping; a further four engines for\u00a0H\u00f6egh\u00a0Autoliner Pure Car and Truck Carriers; and another for a bulk carrier in Japan where the engine is currently on the MITSUI E&S testbed.<\/p>\n Bjarne\u00a0Foldager, Head of Two-Stroke Business,\u00a0Everllence<\/strong>\u00a0said: \u201cThis 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\u00a0\u2013 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. Furthermore, these engines will be digitally connected to\u00a0optimise\u00a0operational performance.<\/em>\u201d<\/p>\n In relation to digital connectivity, the ME-LGIA enables a secure and reliable data flow from vessels to\u00a0Everllence\u00a0shore-based monitoring. This allows the leveraging of real-time engine and operational data to improve performance, provide remote assistance, and help shipowners operate more efficiently and sustainably. As such, data-driven insights have a significant role to play in supporting\u00a0decarbonisation\u00a0as new fuels like ammonia enter the market.<\/p>\n Everllence\u00a0states that the full sales release of the ME-LGIA will initially feature G50, S50, S60, G60, G70 and G80 bore sizes; retrofit options will also, eventually, be made available.<\/p>\n Ammonia as future-fuel its emissions profile makes it a promising carbon-free alternative to traditional fossil fuels with zero CO2, and low\u00a0sulphur-oxide and particulate emissions.

\nAmmonia has several characteristics that mark it out as eminently suitable for deep-sea shipping\u00a0decarbonisation:<\/p>\n
\nammonia\u2019s relatively high volumetric energy-density allows for more compact fuel storage \u2013 especially compared to hydrogen \u2013 critical for large ocean-going vessels. Furthermore, it can be stored as a liquid at moderate pressures, simplifying bunkering compared to cryogenic fuels;
\nits high thermal-efficiency reduces operational costs while maintaining power output;
\nas a widely produced chemical, ammonia benefits from established global supply-chains, lowering long-term costs compared to other e-fuels. Green ammonia production is also currently scaling up via electrolysis, while several blue-ammonia production facilities are already in operation;
\nammonia is especially suitable for two-stroke marine engines because of its inherently slow combustion rate that aligns well with the low piston speeds of these engines.<\/p>\n","protected":false},"excerpt":{"rendered":"
