From near-zero volumes today, JERA has set its sights on being a “pioneer player” in the emerging global value chain for ammonia, handling 7 million tons every year by 2035. JERA is also aiming for 100% substitution of ammonia fuel in ultra-supercritical power stations in the 2040s, and to maintain currently low levels of NOX and SOX emissions from its power generating fleet.
2024 has already been a busy year, with ammonia discussions at an exciting phase. Despite the hesitancy and doubts about ammonia I have heard at recent events, I continue to deliver the same constructive messages, and urge the AEA membership and networks to use the information available to continue to promote ammonia. Our upcoming annual event in New Orleans will explore progress in establishing ammonia markets, and I can’t wait to see you all again in-person.
MAN Energy Solutions has announced one of the first deployments of its ammonia two-stroke engine will take place in Japan. Mitsui E&S will construct the MAN B&W 7S60ME dual-fuel engine, with Imabari Shipbuilding to then install it aboard a Newcastlemax bulk carrier, along with an integrated SCR catalytic converter to treat engine NOX emissions. The news underscores significant momentum for the deployment of marine ammonia engines, with Wärtsilä, WinGD and Mitsubishi Shipbuilding also engaged in ongoing projects.
Hitachi Zozen and NYK will work towards a catalyst-based N2O removal system for ammonia-powered, 2-stroke marine engines.
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.
