Fortescue Future Industries, Maritime and Port Authority Singapore and a host of supporting organisations announced a world-first marine trial in Singapore harbor last week. The vessel sailed on ammonia and diesel dual-fuel in harbor waters, after being loaded with liquid ammonia fuel at Vopak’s Banyan Terminal on Jurong Island. Two years of vessel development and months of safety and training exercises led up to the trial. MPA and Fortescue report that post-combustion NOx levels from the vessel met local air quality standards for Singapore, with further emissions treatment measures to be applied.
AFC Energy, MAHLE, the University of Nottingham and Clean Air Power have been awarded funding from Innovate UK to demonstrate the feasibility of ammonia combustion engines in the marine sector, based on the integration of AFC Energy’s ammonia cracking technology. The new program builds on a prior R&D program exploring ammonia combustion engines for the off-road construction industry.
GE Vernova and IHI Corporation will proceed to the engineering and testing phase for their ammonia gas turbine roadmap for Asia. Based on their efforts in 2022 to demonstrate a low-N2O combustor for a 2 MW, 100% ammonia-fired turbine, IHI will lead development of a two-stage combustor for larger-scale gas turbine models.
MAN Energy Solutions has announced that the first SCR catalytic converter for a marine ammonia engine has passed factory tests and been delivered to Japan. Produced in China by stainless steel specialists BUTTING, the unit is designed to significantly reduce NOx emissions from ammonia combustion engines.
MHI has successfully combustion-tested its ammonia single-fuel burners. The tests confirmed that the burners are capable of complete and stable combustion, producing reduced NOx emissions relative to coal firing. The test will now be run at a larger scale to simulate actual operations.
NYK reports the retrofitting of the LNG-fueled tugboat Sakigake has begun in Yokohama. An ammonia-fueled engine developed by IHI Power Systems, NYK, Japan Engine Corporation and Nihon Shipyard will replace the conventional system on board, with the tug due to hit the water by 2024. NYK & Chilean copper producer CODELCO have also announced they are developing an ammonia-powered Handymax bulk carrier, aiming to develop a fleet to service the cross-Pacific copper trade.
