Powering the Seas Together

In February 2025, Baker Hughes and Hanwha agreed to jointly develop a new small-size (~16 MW power range), 100% ammonia-capable turbine for maritime propulsion applications, to be deployed onboard Hanwha Ocean’s LNG carriers and container ships by 2028. A full gas turbine factory engine test with 100% ammonia is planned to be completed by the end of 2027. The combustion system itself is being developed by Power Systems Mfg., LLC (PSM), and will enable the turbine to be both fully decarbonized and “fuel-flexible” – 100% ammonia combustion to 100% natural gas combustion, and any variable blend in between while meeting…

Initiatives for the Safe Launch of Ammonia-Fueled Capesize Bulk Carriers in 2026

Takanori Mizuno

Mitsui O.S.K. Lines, Ltd. (MOL), the world’s second largest shipping company by fleet size, is set to begin operating 3 ammonia-fueled Capesize bulk carriers from 2026, transporting iron ore and coking coal. This presentation will introduce MOL’s initiatives leading up to the launch, with a particular focus on safety measures and preparations for the safe operation of these next-generation vessels.

WinGD engines installed aboard new gas carriers in South Korea

Julian Atchison June 27, 2025

EXMAR announced this week that a WinGD dual-fuel ammonia engine has now been installed onboard the first of its under-construction vessels in South Korea. Ammonia-fueled ammonia carriers similar to EXMAR’s are currently being built in Korea, China, and Japan, with the first of these vessels to hit the water next year.

R&D recap: the Journal of Ammonia Energy

Geofrey Njovu August 06, 2024

Ahead of the 3rd Symposium on Ammonia Energy in Shanghai next month, we take the opportunity to highlight select papers and key results from the first two editions, starting with the 2022 Cardiff event:

In an ammonia-diesel blending study, Orleans University and WinGD found that minimising the diesel fraction actually led to increased N₂O emissions.
In a bid to produce an optimal ammonia-hydrogen fuel blend, a University of Birmingham team characterised the ammonia cracking mechanism of a new, transition metal-promoted lithium amide catalyst.
A KAUST study of swirl intensity of an ammonia-methane blended fuel finds that increasing the swirl number leads to a more compact flame, reducing NO_X emissions.
A team from the University of Minnesota found that combustion durations comparable to gasoline were obtained for ammonia-hydrogen fuel blends.
And, as part of a joint academic-industry session on safety, it was recommended that a careful, proactive approach is taken towards new ammonia users, likely exposure risk points and deploying maritime ammonia fuel.
