Licensor selection picking up for renewable ammonia synthesis loops
Article

One of the key steps in project development is the selection of the licensor for the renewable ammonia synthesis loop. For renewable ammonia projects, licensors including KBR, Topsoe, Thyssenkrupp Uhde, Casale, and Stamicarbon offer a range of technologies and services covering small to large-scale ammonia production. We explore these different technology offerings, as well as the growing list of projects where they are being deployed.

R&D recap: the <i>Journal of Ammonia Energy</i> – volume II
Article

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 <i>Journal of Ammonia Energy</i>
Article

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.

The 3<sup>rd</sup> Symposium on Ammonia Energy: Shanghai, Sept 22-26
Article

Learn more about the 3rd Symposium on Ammonia Energy, to be held in Shanghai from 22-26 September this year. The AEA is a proud supporter of the event, which will showcase the latest R&D in ammonia energy. Hear from a program of global researchers, take part in industry collaboration workshops, and get the chance to explore local R&D in a series of site visits.

Technology Status: Anion Exchange Membrane (AEM) Electrolysis
Article

Anion Exchange Membrane (AEM) electrolysis combines concepts from alkaline and PEM. Although AEM can potentially offer the best of both worlds compared to conventional technology, challenges such as oxygen sensitivity, stack scale-up and current density still need to be addressed. Germany-based Enapter is leading the commercialization of AEM systems, with other electrolyzer manufacturers now developing their own products.
