Ammonia Energy Conference 2024: Ammonia for Maritime Propulsion is full speed ahead!

Kevin Rouwenhorst November 26, 2024

During the recent 2024 Ammonia Energy Conference, we explored all the latest developments in ammonia-powered maritime propulsion. Engine makers reported strong progress ahead of deployment in 2026, the same year that large-scale vessels will hit the water. The panel explored early operations for the ammonia-powered A-Tug in Japan, as well as ancillary technology systems required for maritime ammonia engines, catalyst after-treatment systems for emission mitigation, and the potential for fuel additives to boost ammonia engine performance.

Sunborne reborn!

Bill David

Despite successfully demonstrating 56kW of controlled combustion of partially cracked ammonia in October 2023, Sunborne Systems was unable to secure Series A funding at the beginning of 2024. Since then, the co-founders have secured UK government funding to tackle two of the challenges set out for Series A funding: to further develop their patented catalysts and to address issues associated with ammonia slippage and NOx emissions. Future opportunities will be discussed.

Ammonia for Boilers in Rural Locations

Agustin Valera-Medina

Currently ~4.5 million tonnes of oil are consumed in the off-mains industrial market annually in the UK. These energy-intensive processes contribute to point source emissions of 14.2 MtCO2/y. Businesses and industries in these locations often cannot rely solely on electricity to satisfy their process heating requirements. Decarbonisation of these sites therefore presents a significant and pressing challenge. Therefore, the Amburn project will develop and demonstrate a 1 MW ammonia-fed steam boiler to help decarbonise off-grid businesses across the UK. Funded by the Department for Energy Security & Net Zero as part of the UK Government’s £55m Industrial Fuel Switching Competition,…

How to give a chemical push to ammonia in a compression ignition engine?

Anne-Gaëlle Morin

The initial work on direct additivation to ammonia in a Rapid Compression machine showed promising results and radical ignition delays and temperature reduction. From these tests on, tests conducted on a research mono-cylinder engine, with the help of the Prisme laboratory at the University of Orléans, demonstrated that the additive used in pilot fuels allowed for better controlled ignition than the pilot fuel alone, better and eased cycle to cycle stabilization and better power output. It also quite dramatically reduced the amount of pilot fuel needed. It seems that the additive helps to keep ammonia in the combustion event even…
