Site items in: Ammonia-Diesel Dual Fuel

R&D recap: the <i>Journal of Ammonia Energy</i>
Article

Ahead of the 3rd Symposium on Ammonia Energy in Shanghai next month, we take the opportunity to highlight select papers and key results from the first two editions, starting with the 2022 Cardiff event:

  • In an ammonia-diesel blending study, Orleans University and WinGD found that minimising the diesel fraction actually led to increased N2O emissions.
  • In a bid to produce an optimal ammonia-hydrogen fuel blend, a University of Birmingham team characterised the ammonia cracking mechanism of a new, transition metal-promoted lithium amide catalyst.
  • A KAUST study of swirl intensity of an ammonia-methane blended fuel finds that increasing the swirl number leads to a more compact flame, reducing NOX emissions.
  • A team from the University of Minnesota found that combustion durations comparable to gasoline were obtained for ammonia-hydrogen fuel blends.
  • And, as part of a joint academic-industry session on safety, it was recommended that a careful, proactive approach is taken towards new ammonia users, likely exposure risk points and deploying maritime ammonia fuel.

The <i>Fortescue Green Pioneer</i> sails in Singapore harbor on ammonia fuel
Article

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.

The Ammonia Wrap: new funding and investment for ammonia energy rolls in, next steps for Uruguay, and Sumitomo to develop a hydrogen
Article

Welcome to the Ammonia Wrap: a summary of all the latest announcements, news items and publications about ammonia energy. This week: new funding and investment for ammonia energy (Starfire Energy, GenCell, Syzygy Plasmonics and Hazer Group), marine engines from the "Ammoniamot" consortium, Uruguay's national hydrogen strategy takes another step, Onahama Port to investigate hydrogen & ammonia imports and Sumitomo to develop Gladstone's hydrogen "ecosystem".

Heavy-duty diesel trucks to be converted to use ammonia fuel in Canada
Article

This week, Hydrofuel Inc announced a commercial demonstration project to convert diesel gensets and transport trucks to run on ammonia fuel, with the conversion work and dual-fuel operations scheduled for a three year period. The CAD $2 million (USD $1.5 million) project will take place at TFX International, in Toronto, and involves the conversion of four existing diesel-fueled assets: two stationary power generators and two transport trucks. These will be converted using Hydrofuel's "aftermarket multi-fuels engine retrofit systems," and they will thereafter be able to operate on a dual fuel basis.

Sturman Industries' Dual-Fuel Ammonia Engine
Article

Eddie Sturman, noted inventor and co-founder of Sturman Industries, has been developing ammonia internal-combustion-engine (ICE) technology for several years – "at least six, maybe more." At the 2016 NH3 Fuel Conference, he provided the most in-depth look so far at the results of Sturman Industries' R&D program. Specifically, his talk featured a dual-fuel compression ignition engine powered by a combination of diesel fuel and ammonia.
