One of the key steps in project development remains the selection of the licensor for the renewable ammonia synthesis loop. We explore different technology offerings from leading licensors – including KBR, Topsoe, Thyssenkrupp Uhde, Casale, Stamicarbon, and GoodChina – as well as the growing list of projects where they are being deployed.
State-owned conglomerate Energy China and logistics and terminal specialist ADF are establishing a renewable ammonia supply chain in northeast China. In our recent episode of Project Features, we explored the Songyuan production project, and ADF’s planned scale-up of ammonia storage and transport facilities across China’s coast.
In our September Episode of Project Features, project partner Lapis Carbon Solutions and LSB Industries walk us through their CCS ammonia project in El Dorado, Arkansas. Permitting is expected to be finalized next year, followed by commencement of CCS operations in late 2026.
Various elements – different definitions for “green” hydrogen, subsidy structures, and transportation & logistics costs – all contribute to the gap between discovered prices for the H2Global and SECI renewable ammonia auctions. More SECI auction results are expected in the coming days and weeks.
Current global ammonia production is mostly based on gas-fed, two-stage reforming processs. Decarbonization of this existing production capacity – as well as new newbuild low-emission capacity also based on gas – can utilize an industrially-proven suite of alternative technologies and processes, including autothermal reforming, and partial oxidation combined with CCS. This article discusses some of the technologies available from various tech providers, and reference projects in operation.
In our recent episode of Project Features, we explored the outcomes from a recent ammonia bunkering demonstration at the Port of Rotterdam. With twelve ammonia transfer and bunkering demonstrations occurring in nine global locations since 2024, where does the Port Readiness Level for ammonia bunkering stand in Rotterdam and elsewhere, what are the key technical learnings, and what gaps remain?
In our June Episode of Project Features, the Institute for Sustainable Process Technology and Sunoco LP joined us to discuss ammonia pipelines. What lessons and best-practices can we draw from existing pipeline networks, and what design & risk mitigation factors are critical to the development of new ammonia pipeline routes?
We explore recent, full-scale, four-stroke engine testing results from IHI and Wärtsilä. Testing indicates N2O emissions can be almost fully eliminated with catalytic treatment, and significantly lower NOX emissions for engines running in ammonia mode, compared to running on diesel. While ammonia slip remains a key consideration due to the design of a four-stroke engine, catalytic treatment of the exhaust can eliminate even high concentrations, and release mitigation systems have already been designed and deployed to ensure safe operations.
In our May Episode of Project Features, OQ Alternative Energy and Dutco joined us to discuss progress on SalalaH2, a renewable ammonia export project under development on Oman’s southwestern coast. Technical specifications, shared infrastructure, and further decarbonization of existing OQ assets at Salalah were explored.
We explore recent, full-scale, dual-fuel engine testing results from leading maritime vendors such as MAN Energy Solutions and WinGD. Testing indicates negligible emissions of the potent GHG N2O (which can be fully eliminated with catalytic treatment), and significantly lower NOX emissions for engines running in ammonia mode, compared to running on fuel oil or diesel. Overall, compliance with IMO Tier II and III emission limits is well within reach for the first generation of ammonia-fueled maritime engines.
