Gas-based reforming for low-emission ammonia production: ATR, POX, and two-step reforming

Kevin Rouwenhorst August 06, 2025

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.

Ammonia bunkering: moving from demonstrations to operations

Kevin Rouwenhorst July 28, 2025

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?

Ammonigy, Heraeus: successful four-stroke engine demonstration

Julian Atchison July 23, 2025

Ammonigy, Heraeus Precious Metals and the Technical University of Darmstadt have partnered to demonstrate operations using cracked ammonia fuel in a four-stroke MAN test engine. The performance and efficiency of the test engine when running on ammonia-hydrogen fuel was comparable to natural gas operations, and use of an exhaust aftertreatment system reduced potentially harmful nitrogen-based emissions to near-zero levels.

As a resource-constrained nation, Singapore needs to secure long-term supplies of low-carbon energy. Keppel Infrastructure is leading several decarbonization opportunities, including a pathfinder project for ammonia power generation and bunkering on Jurong Island. A series of challenges confronts Singapore as it seeks to secure fuel supplies, including price competitiveness and certification of incoming fuels.
