Demonstrating CCS-based ammonia technologies in Japan

Kevin Rouwenhorst July 26, 2023

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.

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

Kevin Rouwenhorst June 28, 2023

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.

Solid oxide electrolysis: building capacity

Kevin Rouwenhorst May 22, 2023

Solid oxide electrolysis has recently gained traction, and is fast becoming an attractive technology option for new ammonia production projects. This week we will explore a recent ISPT report, the scale-up of Topsoe’s manufacturing capacity, and several project announcements.

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

Kevin Rouwenhorst May 15, 2023

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

Kevin Rouwenhorst April 27, 2023

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

Kevin Rouwenhorst April 13, 2023

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

Kevin Rouwenhorst March 08, 2023

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.

Coupling solid oxide electrolysis to ammonia production

Kevin Rouwenhorst February 07, 2023

In our January episode of Ammonia Project Features, we explored the current commercial status of solid oxide electrolysis, and its potential to be integrated with ammonia production. Rick Beuttel (Bloom Energy) and Jakob Krummenacher (LSB industries) also discussed the utilization of the technology in a new decarbonization project at LSB’s ammonia plant in Pryor, Oklahoma.

Technology status: ammonia production from electrolysis-based hydrogen

Kevin Rouwenhorst January 31, 2023

Electrolysis-based ammonia production peaked worldwide around 1970, before the economies of scale and cheap gas feedstock led to its decline. With decarbonization and climate-neutral industrial processes now a critical priority, electrolysis-based ammonia production has re-emerged as a long-term solution. From a base of 10,000 tonnes per year worldwide production in 2020, as much as 100 million tonnes per year of electrolysis-based ammonia could be produced by the end of this decade, driven by a dramatic roll-out of renewable energy generation and installed electrolyzer capacity.

Renewable ammonia opportunities in Egypt

Kevin Rouwenhorst December 18, 2022

For our December episode of Ammonia Project Features, we welcomed Alzbeta Klein (International Fertilizer Association) and Tarek Hosny (Fertiglobe). Our speakers discussed a pathway forward for Egypt’s fertilizer industry to decarbonize, presented the newly-commissioned Egypt Green Hydrogen project, and outlined the unique advantages (and challenges) of developing renewable production projects in Egypt.
