Australia’s national research organisation CSIRO is contributing valuable R&D across the hydrogen and ammonia value chains. At Ammonia Energy APAC 2023, we’ll hear updates on some key ammonia energy projects at CSIRO: small-scale production, combustion engines, and fuel cells, as well as an ongoing partnership with Fortescue Future Industries to develop & deploy metal membrane technology for ammonia cracking systems.
Chinese automotive manufacturer GAC Group has unveiled its first ammonia-powered, 120 kW engine for passenger cars at a recent showcase event in Guangzhou.
A joint study into ammonia safety onboard three different vessel types has found that safety risks of ammonia fuel can be mitigated, but only if technical safeguards are implemented and key “human factors” are addressed. The new report sets out a series of recommendations to ensure acceptable risk levels for crew on-board ammonia-fueled vessels.
Two ammonia-ready vessels - the CMA CGM Masai Mara and the ALS Ceres - were delivered this May. Both are the first in a series of six containerships contracted to be built at different Chinese shipyards.
A new MoU between WinGD and Mitsubishi Shipbuilding will see the deployment of WinGD’s X-DF-A ammonia-fueled engines to a range of vessels. In Norway, Wärtsilä has unveiled a safety system designed for continuous onboard monitoring of ammonia leaks, featuring a staged combustion process to deal with accidental releases. And classification society DNV has awarded AiP to two significant ammonia-fueled vessel designs: the MS NoGAPs, and Viridis Bulk Carriers’ short sea bulk carrier.
Norwegian technology developer Pherousa announced that it has developed & validated an ammonia cracking-based propulsion system, with plans to order six Ultramax vessels fitted with the technology. Grieg Maritime has ordered up to four ammonia-ready bulk carriers from China State Shipbuilding Corporation for delivery in 2026. And a new container ship design has been unveiled by the Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping.
ABS has used computational fluid dynamics to model ammonia dispersion patterns in a ship’s engine room, with the aim of producing a fast, real-time response system for ammonia leaks. In Japan, a fuel supply system for large-scale, low-speed, two-stroke marine engines is undergoing final verification testing. Mitsubishi Shipbuilding aims to become a key technology provider of such systems, and in the ammonia maritime fuel space.
As part of our Maritime Ammonia Insights webinar series, we explored the safety learnings gained so far during the development of maritime ammonia fueled engines, as well as existing best practices for safe ammonia handling. John Mott (ASTI), Kaj Portin and Laura Sariola (both Wärtsilä) were joined in conversation by Conor Furstenberg Stott.
Successful testing has been completed at IHI’s facilities in Ota, Japan. A four-stroke marine engine - fully integrated with exhaust gas aftertreatment and fuel supply systems - produced stable operations running on up to 80% ammonia fuel. Emissions of dinitrogen monoxide (N2O) and ammonia slip were reported as “virtually zero”.
Norway-based North Ammonia will supply at least 100,000 tonnes per year of ammonia fuel to Höegh Autoliners from 2030, powering their future fleet of Aurora class car carriers. Grid-based electrolysis will feed production of ammonia in Eydehavn on Norway’s south coast, with bunkering to take place somewhere in the Amsterdam-Rotterdam Antwerp area. In more maritime ammonia news out of Norway this week, Skarv Shipping will receive government funding to develop cargo vessels featuring ammonia-powered, four-stroke engines.
