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.
Asahi Glass Corporation announced it has successfully used 100% ammonia fuel to produce architectural glass over two days of testing at its Yokohama Technical Center, with NOx emissions below environmental thresholds. The news follows successful ammonia co-firing tests to produce cement clinker by Mitsubishi UBE Cement Corporation.
This week, we explore three new onboard systems: the Mitsubishi Ammonia Supply and Safety System (MAmmoSS®), Singapore-based C-LNG Solutions’ new ammonia low flash point fuel supply system, and a new NOx emission mitigation system developed by Korea Shipbuilding & Offshore Engineering and Hyundai Heavy Industries.
