Mitigating emissions risks from ammonia-powered vessels
Article

Technology solutions to manage emissions from ammonia-powered internal combustion engines will be commercially available on a similar timeline to the engines themselves, a new report from the Mærsk Mc-Kinney Møller Center concludes. Although the authors are confident ammonia combustion emissions (including the potent greenhouse molecule N2O) will be successfully minimised, key gaps include a lack of industry-wide emissions thresholds and a poor understanding of the well-to-tank emissions of ammonia fuel, particularly CCS-based ammonia.

New ammonia-powered vessel designs win AiP
Article

Three new ammonia-powered, bulk carrier designs have recently been awarded Approval in Principle. In China, SDTR Marine & SDARI’s Kamsarmax dual-fuel design received AiP from the China Classification Society. In Japan, another Kamsarmax-sized vessel developed by Sumitomo and Oshima Shipping was approved, and ClassNK has signed off on a Capemax vessel designed by MOL and Mitsui & Co., which includes an ammonia-powered main engine and hard sails to improve energy efficiency.

Maritime ammonia: fuel cell propulsion systems, car carriers & bunkering in Germany
Article

In maritime ammonia updates this week:

  • Alma Clean Power’s containerised SOFC system design has been granted AiP by DNV. A 2 MW, ammonia-fed system will be used to retrofit the Viking Energy vessel as part of the ShipFC project.
  • Grimaldi Group has increased its order for ammonia-ready car carriers to fifteen. China Merchants Heavy Industries will construct the 9,000 car equivalent units design at Jiangsu shipyards, delivering the first vessels in 2025.
  • Mabanaft and Hapag-Lloyd will explore the supply of ammonia bunker fuel to Hapag’s vessels at the Port of Hamburg (Germany), and the Port of Houston (USA).
  • and the German Federal Ministry for Economic Affairs and Climate Action will fund the construction of three, future-proof LNG bunker vessels, which are designed to be upgraded to handle ammonia fuel.

COP27: the Green Shipping Challenge
Article

The US and Norway launched the Green Shipping Challenge in Sharm el-Sheikh this month. The Challenge encompasses more than forty different announcements & initiatives, including ammonia fuel production in Namibia, ammonia-powered cargo shipping in Finland, ammonia-powered pilot vessels in Norway's Green Shipping Programme, and a host of new green corridor projects. A trio of new reports have also provided an assessment of progress to date in green corridor development, and suggested key next steps.

Ammonia-powered Aframaxes
Article

Thailand’s state-owned oil & gas organisation PTT and Singapore-based AET Tankers have agreed to jointly develop two dual-fuel Aframax vessels, with the intention of powering them with ammonia fuel. AET will select a shipyard for construction, with the two vessels to be delivered to PTT for long-term charters by early 2026.

Fortescue & Deutsche Bahn to develop ammonia-powered trains in Germany
Article

Deutsche Bahn and Fortescue Future Industries will collaborate to modify existing locomotive diesel engines to run on hydrogen & ammonia fuel. The pair will utilise Ammonigy’s ammonia cracking technology in their design, with a prototype, bench-top engine currently undergoing testing in Germany. This week FFI also signed an agreement to develop a new energy import terminal in Wilhelmshaven.

Exhaust gas treatment catalysts for ammonia-fueled engines
Presentation

Ammonia is expected to be a promising zero-emission fuel because it does not emit CO2 during combustion. However, the exhaust gas from the actual ammonia-fueled engines contains unburned ammonia, nitrogen oxides (NOx), and nitrous oxide (N2O), and there is a need to develop technologies to remove these harmful substances. Unburned ammonia can be removed by a catalytic combustion method using a conventional oxidation catalyst, but NOx and N2O are simultaneously generated as byproducts. Therefore, Nikki-Universal has developed a new catalyst that can remove ammonia at high efficiency while reducing the generation of NOx and N2O. We have also developed a…
