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.

India: a future ammonia energy giant

Although a globally significant ammonia producer, India still relies on ammonia & fertilizer imports to support its agricultural sector. In our recent episode of Ammonia Project Features, we explored the potential of domestically-produced renewable ammonia to both replace these imports and position India as an ammonia energy giant. Excellent solar PV resources, plentiful government support and access to “round-the-clock” renewables were all highlighted as key drivers for India to meet its renewable ammonia potential.

HyEx: ammonia from the Chilean desert

In our latest episode of Ammonia Project Features, Asunción Borras (Engie) and Pablo Wallach (Enaex) presented the HyEx project. Although a historical exporter of nitrogen fertilizers, Chile is now a major importer of ammonia, particularly as a feedstock for manufacturing mining explosives. Solar PV generating potential in Chile’s Atacama desert is among the world’s best, and the HyEx project will leverage this to produce renewable ammonia. By 2030, HyEx could produce enough ammonia to completely replace Enaex’s current ammonia imports, with volume left for exports or other applications.
