Speaker: Johan Hult, Principal Engineer - Everllence
Abstract
Ammonia is widely considered the fuel of choice for decarbonising the shipping industry. Everllence has developed an ammonia burning engine which is now ready for commercial application in a wide range of ships. We have demonstrated that a high efficiency combustion process combined with low laughing gas emissions is possible, with greenhouse gas savings exceeding 90%.
An optimised injection system in combination with selective catalytic reduction also ensures low ammonia and NOx emissions. The first commercial engine tested has a power of 13 MW, and is expected to be out on the ocean before the end of 2026. Johan will present their development of the ammonia engine and also give an outlook on the other green fuels of interest to the marine market, such as methanol and ethanol.
