Everllence: Two-stroke ammonia engine poised for maritime debut

A two-stroke ammonia engine manufactured by German marine engine producer Everllence (formerly known as MAN Energy Solutions) is all but ready to hit the maritime industry market.

As disclosed on November 13, Everllence’s dual-fuel ME-LGIA (-liquid gas injection ammonia) engine, which was unveiled for the first time at a recent maritime conference, is now prepared for newbuilding orders.

As noted, the inaugural unit of the ME-LGIA engine is set to be handed over in the first quarter of 2026, with bedding-in scheduled for the end of this year.

According to officials from Everllence, the brand-new engine is based on the diesel principle as well as the dual-fuel liquid gas injection concept, and it offers the same ‘benefits’ as the company’s existing ME-LGIM and ME-LGIP units, which, respectively, run on methanol and liquefied petroleum gas (LPG).

That said, given the particular characteristics that come with ammonia, the new engine reportedly possesses additional safety features, such as containment systems, system ventilation and double-walled piping development specifically engineered for using this alternative fuel source.
