Technology Status: Anion Exchange Membrane (AEM) Electrolysis

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.

Mitsui O.S.K. Lines: forging ahead with a comprehensive strategy for maritime ammonia

Earlier this year, the Japanese shipping giant declared a strategic direction which included a substantial role for low carbon ammonia. In our latest episode of Maritime Insights we explored the scope of this new strategy, MOL’s future fuels roadmap, and the wide range of initiatives in play to construct a full value chain for fuel ammonia (including mega-scale production projects).

Demonstrating CCS-based ammonia technologies in Japan

Our June episode of Ammonia Project Features focused on a new project in Niigata prefecture, which will demonstrate low-carbon, fossil-based ammonia production with a capacity of 500 tonnes per year. As part of the project, Japanese government organization JOGMEC will work with INPEX to develop enhanced gas recovery & CO2 sequestration monitoring technologies. Tsubame BHB will deploy its low-temperature, low-pressure ammonia synthesis technology based on an electride-supported catalyst developed at the Tokyo Institute of Technology.

Safety and the marine ammonia engine

As part of our Maritime Ammonia Insights webinar series, we explored the safety learnings gained so far during the development of maritime ammonia fueled engines, as well as existing best practices for safe ammonia handling. John Mott (ASTI), Kaj Portin and Laura Sariola (both Wärtsilä) were joined in conversation by Conor Furstenberg Stott.

Hydro-electric ammonia: project design, engineering & technology selection

To design, build & operate a hydroelectric ammonia production plant fed by electrolytic hydrogen, what considerations need to be taken into account? Our recent episode of Ammonia Project Features explored this question, focusing on an upcoming project being developed in Paraguay by ATOME, URBAS and Casale. The use of surplus hydropower, existing industrial infrastructure, proactive engineering and commercially-available, flexible ammonia synthesis technologies all adds up to a less challenging task for developers, and a potential project template going forward.

Flexible ammonia synthesis: shifting the narrative around hydrogen storage

Flexible ammonia production technology is currently scaling up to meet the challenges of fluctuating electricity feedstock. The ability to ramp down plants to 5 - 10% of their nominal load will minimize the requirement for hydrogen storage buffers and reduce the overall cost of renewable ammonia production. The first demonstration-sized flexible ammonia plants are due to begin operations later this year.
