Decarbonizing existing, SMR-based ammonia plants: workshop recap
Article

Decarbonization of existing steam methane reforming-based ammonia plants is possible, and changes in gas and heat flows can be recovered via alternative technologies. Recap our workshop in Atlanta, where we discussed the use of upstream methane monitoring equipment, electrolysers, carbon capture, hydrogen burners, energy storage and electric heating to achieve decarbonization of conventional ammonia plants.

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

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.

Coupling solid oxide electrolysis to ammonia production
Article

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.

How to reduce the LCoA of green NH3 with hybrid CSP-PV plants
Presentation

The gNH3 production requires a large amount of renewable energy, where the LCoA is strongly affected by the LCoE. If it is considered only a solar solution, the low Photovoltaic (PV) technology cost can achieve competitive gH2 cost. However, the industrial NH3 plant would require power stability in a 24/7 profile, and a storage solution must be included. In this case, the Concentrating Solar Power (CSP) presents an unique and promising advantage with its dispatchability to fulfill this necessity. Therefore, a hybrid CSP+PV solution can give the best cost solution power mix for the green ammonia industry.

Dynamic Analysis of Flex-gNH3 – a Green Ammonia Synthesis Process
Presentation

The future of a decarbonised ammonia production is seen as the alignment of the intermittent production of renewable energy, energy demands and ammonia process features. The current Haber-Bosch ammonia synthesis process can indeed be altered to enable green and sustainable ammonia production primarily being driven by renewable electricity. However, this will require to enhance current commercial Haber-Bosch (H-B) process flexibility with modifications to redefine the conventional H–B process with a new optimised control. The technical feasibility of green-ammonia (gNH3) process had been widely discussed and analysed focusing on its energy efficiency, the development of small-scale, distributed, modularised processes that can…
