Emission performance of ammonia-fueled, four-stroke marine engines

Kevin Rouwenhorst June 03, 2025

We explore recent, full-scale, four-stroke engine testing results from IHI and Wärtsilä. Testing indicates N₂O emissions can be almost fully eliminated with catalytic treatment, and significantly lower NO_X emissions for engines running in ammonia mode, compared to running on diesel. While ammonia slip remains a key consideration due to the design of a four-stroke engine, catalytic treatment of the exhaust can eliminate even high concentrations, and release mitigation systems have already been designed and deployed to ensure safe operations.

New ISPT report: design and safety for large-scale ammonia pipelines

Kevin Rouwenhorst May 26, 2025

ISPT’s new report explores the design, technical, and safety considerations of a theoretical 550 km ammonia pipeline linking the Port of Rotterdam to Karlsruhe in Germany, carrying 7 million tons per year of ammonia.

Class societies prepare for marine ammonia fuel: safe operations, crew training, and risk management

Julian Atchison May 18, 2025

ClassNK, DNV, Lloyd’s Register and the American Bureau of Shipping have all released new resources to support the implementation of marine ammonia fuel. We explore vessel operation guidelines and best-practice recommendations, seafarer training programs, and models for ammonia leak dispersion onboard vessels.

Webinar

Ammonia pipelines: existing networks, future deployments, and safety considerations

Julian Atchison

Meet the Institute for Sustainable Process Technology (ISPT) and Sunoco LP to explore plans for new ammonia pipelines in Europe, as well as operational & safety lessons learned from existing networks in the USA.

Emission performance of ammonia-fueled, two-stroke marine engines

Kevin Rouwenhorst May 06, 2025

We explore recent, full-scale, dual-fuel engine testing results from leading maritime vendors such as MAN Energy Solutions and WinGD. Testing indicates negligible emissions of the potent GHG N₂O (which can be fully eliminated with catalytic treatment), and significantly lower NO_X emissions for engines running in ammonia mode, compared to running on fuel oil or diesel. Overall, compliance with IMO Tier II and III emission limits is well within reach for the first generation of ammonia-fueled maritime engines.

Ammonia fuel for industrial ceramics manufacturing

Kevin Rouwenhorst May 02, 2025

In the latest episode of Project Features, Foshan Xianhu Laboratory and Monalisa Group explored a recent demonstration of ammonia combustion for industrial fabrication of ceramic tiles in China. Retrofits of the gas-powered production lines, safe, low-emission ammonia combustion, a multi-level DeNO_X approach, target markets, and future ammonia fuel demand potential in China were discussed.

UK Coastguard, Department of Transport: preparing for ammonia-fueled vessels

Julian Atchison April 25, 2025

The UK’s Maritime and Coastguard Agency has set out timelines and processes for operators of ammonia-fueled vessels to engage with authorities in preparation for operations in UK waters. Ammonia fuel is included in the Department of Transport’s first-ever Maritime Decarbonisation Strategy, with as much as 70% of the forecast fuel mix being ammonia by 2050.

First ammonia bunker pilot completed in Rotterdam

Julian Atchison April 21, 2025

Facilitated by the Port of Rotterdam, Trammo, OCI, James Fisher Fendercare successfully completed a ship-to-ship transfer of ammonia between two vessels berthed at APM Terminals Maasvlakte earlier this month. The successful pilot raises the Port of Rotterdam’s “Port Readiness Level” for marine ammonia fuel to the deployment phase.

Singapore Maritime Week: decarbonizing shipping with Australia and other key partners

Julian Atchison March 31, 2025

At Singapore Maritime Week, Maritime & Port Authority of Singapore and Australia’s national science agency CSIRO announced funding for eight maritime decarbonization projects, including ammonia safety training, and an AI-based safety management system. MPA also signed agreements with ABS, the Ports of Rotterdam and Antwerp-Brugges, and confirmed it has contributed to early work on training guidelines for the safe handling of methanol and ammonia at the IMO.
