COP27: the Green Shipping Challenge

Julian Atchison November 25, 2022

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

Julian Atchison October 10, 2022

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

Julian Atchison October 10, 2022

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

Issei TsujiTomoo IkomaHiroki OkamotoNobuyuki AoiToshiya NashidaYasushi Fujimura

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…

Wärtsilä launches new multi-fuel maritime engine

Julian Atchison September 21, 2022

Wärtsilä has just launched its medium-speed, 4-stroke, Wärtsilä 25 engine, intended to be the first Wärtsilä engine to run on ammonia fuel. From 2023 a technology upgrade will be commercially available to allow the engine to run on alternative fuels like ammonia, with a fully-compliant NOx abatement system already available when running on fossil-based fuels. At the recent Australia conference, MAN ES reported that their two-stroke ammonia engine will be commercially available in 2024, with testing to commence next year.

Developing ammonia maritime engines & fuel: a collaborative approach

Conor Furstenberg Stott September 02, 2022

The latest episode of Maritime Ammonia Insights webinar centred around collaboration, leadership & Singapore: three critical elements in the maritime ammonia transition. Sofia Furstenberg Stott was joined by Peter H. Kirkeby (MAN Energy Solutions) and Yi Han Ng (Maritime and Port Authority Singapore), who discussed timelines for engine development, the benefits of a consortia approach, and the all-important safety & technical progress of maritime ammonia technologies.

Singapore: investments, a green corridor partnership and a new bunkering vessel project

Julian Atchison August 18, 2022

Singapore’s sovereign wealth fund GIC and UK-based Carlyle will both invest in the development of Eneus Energy’s renewable ammonia project pipeline, with plants in the US and UK planned. The Maritime & Port Authority Singapore and Port of Rotterdam have agreed to establish a green maritime corridor by 2027. The agreement will help accelerate the deployment of alternative maritime fuels like ammonia on the critical shipping route, which links two of the world’s largest bunkering ports. And a trio of organisations - PaxOcean Engineering, Hong Lam Marine and Bureau Veritas will jointly develop an ammonia bunkering vessel design.
