First Ammonia Motors has successfully demonstrated a pure ammonia-fed V8 engine, which utilises proprietary onboard heat recycling and ammonia cracking technology to generate hydrogen as a combustion co-fuel.
Japan Engine Corporation has announced commercial readiness for its new 2-stroke, dual-fuel engine. The first engine unit will be installed on an ammonia-fueled medium gas carrier next month, with the vessel scheduled to enter service in 2026.
Everllence (formerly MAN Energy Solutions) will supply four 7S60ME-LGIA dual-fuel engines to Höegh Autoliners, for installation aboard Höegh’s new Aurora-class car carriers.
Ammonigy, Heraeus Precious Metals and the Technical University of Darmstadt have partnered to demonstrate operations using cracked ammonia fuel in a four-stroke MAN test engine. The performance and efficiency of the test engine when running on ammonia-hydrogen fuel was comparable to natural gas operations, and use of an exhaust aftertreatment system reduced potentially harmful nitrogen-based emissions to near-zero levels.
Ammonia cracking tech provider Ammonigy and leading German brick manufacturer Juwö Poroton led the project, successfully demonstrating a pilot-sized brick kiln that runs on cracked ammonia fuel gas. The cracked ammonia-fired bricks were virtually “indistinguishable from bricks fired with natural gas”.
IHI and GE Vernova have built a large scale combustion test facility which will accelerate the development of gas turbines capable of operating on 100% ammonia. The two parties aim to have such gas turbines commercially available by 2030.
