Site items in: NOx Emissions

Article

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 NOX 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.

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 DeNOX approach, target markets, and future ammonia fuel demand potential in China were discussed.

Here, we explore the current demonstration landscape for large-scale cracking. To produce pipeline-quality hydrogen at future energy import hubs, industrial-scale ammonia cracking is still to be derisked and demonstrated, although certain parts of the overall process have been proven at scale. What are the technology elements to be considered, and who are the first-movers deploying the technology in a variety of global locations?

2025 is a critical year for the adoption of ammonia fuel in shipping. Here, we preview important upcoming meetings of the International Maritime Organization, what regulatory gaps are being filled by this work, potential candidates for decarbonization measures, and progress in engine development. All this sets the scene for incredible progress to be made in the coming years.

With commercial deployment scheduled to start this June, both WinGD and MAN ES’s under-development ammonia fueled engines have reported promising results across performance, ammonia safety and emissions optimisation parameters. MAN ES and MITSUI have also commenced a commercial-scale prototype test of the MITSUI-MAN ES large-bore, low-speed, two-stroke ammonia engine in Tamano, Japan.

The view from Japan: 2025 shaping as a pivotal year for ammonia energy
Article

In 2025, the pieces are rapidly assembling to enable and accelerate imports of ammonia energy to Japan. This year, government agency METI is due to announce two lots of key funding, including contracts for difference subsidies and development of import infrastructure. Power generation technologies will be commercialised within the next few years, and more maritime players are joining the push to deploy ammonia fuel in Japanese ships.
