R&D recap: the Journal of Ammonia Energy
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.

Yanmar, Amogy to collaborate on marine combustion engines
The pair will explore the integration of Amogy’s ammonia cracking technology with Yanmar’s under-development hydrogen internal combustion engine. Yanmar is a leading provider of marine engines for small-scale marine propulsion, and has also commercialised a hydrogen fuel cell system.

Ammonia cracking in H2SITE membrane reactors
In our May episode of Project Features, H2SITE joined us to explore the development history of their Palladium membrane-based, ammonia cracking technology. Learn more about the deployment of this technology at a hydrogen vehicle refueling site in the UK, plus plans for scaling-up the technology to produce tons per day of fuel-cell grade hydrogen from ammonia.

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

Höegh LNG, Deutsche ReGas to develop floating ammonia cracker
The pair will develop a new ammonia import hub in north Germany on the Baltic Sea coastline. The terminal will feature a floating ammonia cracker, producing around 30,000 tons of hydrogen per year for injection into the German Hydrogen Core Network.

KIER unveils improved ammonia cracking system
The Korea Institute of Energy Research has successfully demonstrated an upgraded version of its ammonia cracking system. The new system eliminates the use of LNG or LPG as reaction heat source and introduces a single-step process for hydrogen separation from the tail gas.

Amogy: technology deployment on construction sites, supply vessels
Amogy’s ammonia-to-electrical power system will be used to charge Terox’s electric construction vehicles, thanks to a new commercial partnership in Norway. It will also be deployed onboard Hanwa Ocean’s ammonia-fueled supply vessels.

New ammonia cracking systems under-development in Japan
Mitsubishi Heavy Industries and NGK Insulators will jointly develop a membrane-based purification system to produce high-purity hydrogen from ammonia cracking. Also in Japan, Toyo Engineering and Nippon Seisen will lead development of a small-scale ammonia cracking unit, producing on-demand hydrogen for vehicle fuel and power generation.
