Powering the Seas Together

Luca PilengaSemi KimJeff Benoit

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…

Ammonigy, Heraeus: successful four-stroke engine demonstration

Julian Atchison July 23, 2025

Ammonigy, Heraeus Precious Metals and the Technical University of Darmstadt have partnered to demonstrate operations using cracked ammonia fuel in a four-stroke MAN test engine. The performance and efficiency of the test engine when running on ammonia-hydrogen fuel was comparable to natural gas operations, and use of an exhaust aftertreatment system reduced potentially harmful nitrogen-based emissions to near-zero levels.

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 NOX 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.

Onboard cracking, fuel storage and adhering to emissions standards: highlights from the MariNH3 conference

Geofrey Njovu July 10, 2024

At last month’s MariNH3 conference in Nottingham, a series of keynotes laid out the opportunities and challenges ahead for marine ammonia fuel. Onboard ammonia cracking technologies are moving through testing phases and closer to commercialisation, vessel designers are working through the unique challenges of carrying ammonia fuel onboard, and emissions mitigation technology (in combination with adherence to existing Tier 3 standards) will be necessary to ensure that ammonia-powered vessels are more environmentally-friendly than conventional counterparts.

Marine ammonia combustion engines under development in the UK

Julian Atchison February 14, 2024

AFC Energy, MAHLE, the University of Nottingham and Clean Air Power have been awarded funding from Innovate UK to demonstrate the feasibility of ammonia combustion engines in the marine sector, based on the integration of AFC Energy’s ammonia cracking technology. The new program builds on a prior R&D program exploring ammonia combustion engines for the off-road construction industry.
