MAN Energy Solutions (MAN ES) has announced a key development in its ME-LGIA (Liquid Gas Injection Ammonia) engine project as full-scale testing begins at its Research Centre Copenhagen. This marks a significant step in the company’s effort to develop ammonia as a viable marine fuel.

Ole Pyndt Hansen, head of two-stroke R&D at MAN ES, highlighted the importance of this milestone: “Having already completed more than 12 months of testing on a single cylinder running on ammonia, it’s a significant milestone to be able to step up to full-scale engine testing. We have been busy with the conversion process over the past few months, including ensuring that all safety provisions work according to our requirements. We are now ready for the next phase that will focus on, among other parameters, combustion and emissions, engine-tuning, atomizer testing, and control-system verification. This is provisionally set to continue until mid-2025.”
