First Ammonia Motors has successfully demonstrated a pure ammonia-fed V8 engine, which utilises proprietary onboard heat recycling and ammonia cracking technology to generate hydrogen as a combustion co-fuel.
Japan Engine Corporation has announced commercial readiness for its new 2-stroke, dual-fuel engine. The first engine unit will be installed on an ammonia-fueled medium gas carrier next month, with the vessel scheduled to enter service in 2026.
Everllence (formerly MAN Energy Solutions) will supply four 7S60ME-LGIA dual-fuel engines to Höegh Autoliners, for installation aboard Höegh’s new Aurora-class car carriers.
GMF’s new report finds that both ammonia and methanol fuels are now “ready” for commercial deployment, but a concerted push is required to enable scale-up beyond 2030. The report highlights the increased familiarity (and confidence) from key maritime stakeholders with ammonia fuel, and a recommendation to independently verify emissions from the first ammonia-fueled vessels.
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?
The European Commission has unveiled the Hydrogen and Gas Market Directive which in addition to existing regulations on renewable fuels of non-biological origin (RFNBO) set out in the Renewable Energy Directive, completes the policy framework for the sector on the European continent.
Hintco is inviting applications from renewable hydrogen and related fuel producers to participate in its supply-side auctions focussing on bidders from Africa, Asia, America & Oceania, and North America.
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.
Ammonia cracking tech provider Ammonigy and leading German brick manufacturer Juwö Poroton led the project, successfully demonstrating a pilot-sized brick kiln that runs on cracked ammonia fuel gas. The cracked ammonia-fired bricks were virtually “indistinguishable from bricks fired with natural gas”.
