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.

MAN Energy Solutions 2 stroke Ammonia engine

Kjeld Aabo

The marine industry is convinced that Ammonia is not only a very strong candidate as a future fuel, but also that Ammonia will be one of the leading future fuels. MAN Energy solutions has worked since 2019 on the development of a two stroke engine burning Ammonia by using the Diesel principle (as used for other fuels such as Methane , Methanol, Ethane and LPG) In this presentation, we will give an update on the engine design, which we will start testing in Copenhagen in Oct. 2022. The first ammonia engine (with final engine design and combustion process) is scheduled…

Ammonia solutions for the UK construction industry

Julian Atchison July 19, 2022

The UK government will fund a new red diesel replacement project from engine developers MAHLE Powertrain and partners Clean Air Power and the University of Nottingham. The trio will demonstrate decarbonisation of heavy duty engines using ammonia and hydrogen fuel, or a blend of the two. Fortescue Future Industries and Liebherr are also involved in the decarbonisation of the UK construction sector, with agreements on hydrogen fuel supply & engine development signed last October. Fuel cells also enter this mix, with AFC Energy currently rolling out off-grid, ammonia-powered gensets on construction sites in London and Madrid.

Maritime actors push on with overcoming ammonia fuel safety concerns

Conor Furstenberg StottSofia Furstenberg Stott July 18, 2022

Two recent reports (one from Bureau Veritas & Total, the other from the Together in Safety consortium) illustrate just how seriously the maritime industry is pursuing low carbon ammonia fuel. While progress in the maritime ammonia space is impressive, safety risks are widely-acknowledged and work remains to be done.

Both reports identify key hazards facing adoption of ammonia as a maritime fuel, and echo points heard before in the development of methanol & LNG as maritime fuels: high-risk hazards currently exist that must be eliminated, mitigated or controlled. But Together in Safety concludes the way forward will be via collaboration & shared responsibility - something we’re already seeing in the multiple high-profile safety studies and consortia working around the globe. Thankfully, the willingness of significant maritime players to engage on ammonia and the momentum for change are both high.
