Renewable ammonia in China: full speed ahead

China is keeping pace with IEA predictions for electrolyzer installations, with as much as 55% of the world’s total capacity to be installed there by 2028. Coupled with strong wind-power resources, domestic manufacturing capabilities and multiple economic drivers to transition away from coal-based ammonia production, China is ideally positioned to speed up the deployment of renewable ammonia projects.

Renewable ammonia exports from Brazil: Project Iracema

In our latest episode of Ammonia Project Features, we explored Project Iracema: a grid-connected, renewable ammonia production facility under-development in Pecem, northeast Brazil. To discuss Brazil’s unique electricity market, project details and the important role of certification to the project, AEA Technology Manager Kevin Rouwenhorst was joined by Jonas Rechreche (Proton Ventures), Matheus Kleming (Casa dos Ventos) and Ricardo Gedra (CCEE).

Thorium-powered ammonia production in Indonesia

In our September episode of Ammonia Project Features, Pupuk Kaltim and Copenhagen Atomics joined us to explore their new, nuclear-powered ammonia project in Bontang, East Borneo. Cophenagen’s Thorium-fed, Onion Core® reactor design will be integrated with solid oxide electrolysers and an existing ammonia synthesis loop to produce more than one million tonnes per year of low-carbon ammonia.

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.

China: scaling-up “flexible” ammonia production powered by renewable energy

The cost gap between fossil-based ammonia production and electrolysis-based ammonia production in China is arguably the smallest in the world. In our May episode of Ammonia Project Features, we explored two new, “flexible” renewable ammonia projects being developed in northeast China, as well as some of the engineering challenges as we scale-up electrolysis plants to gigawatt-sized.

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.
