R&D recap: the Journal of Ammonia Energy – volume II
Ahead of the international Symposium on Ammonia Energy event next month, we recap R&D presented in the second edition of the Journal on Ammonia Energy:
- An integrated, indirect ammonia solid-oxide cell featuring a heat exchanger and ammonia cracker was modelled, built and tested by the UK’s Science and Technologies Council (STFC).
- The techno-economics of the transportation of energy from Orkney, Scotland to Milford Haven, Wales using ammonia as an energy carrier transported by ship may be the most cost-effective option.
- N2O and NOX conversion in ammonia engine exhausts is limited by the presence of oxygen and water, presenting an optimisation challenge for technology developers.
- And an academic-industry joint session on ammonia safety highlighted multiple projects currently underway to tackle the risks associated with the use of ammonia in new commercial sectors.

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.

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.
