The potential of ammonia as fuel
Page date: Published 9 Dec 2024; updated 30 Sep 2026. 3 min read.
The article explains ammonia (NH3) as a potential maritime fuel and hydrogen carrier. It distinguishes fossil-fuel-based “grey/brown” ammonia from “green” ammonia made with renewable energy, and notes that production pathways affect emissions. It states that ammonia can be liquefied at comparatively low pressure and could be cracked into hydrogen near its point of use. The page quotes a 116% annual growth forecast for the green-ammonia market from 2024 to 2030; this is a forecast, not a current measured growth rate.
The article describes ammonia fuel cells as cracking NH3 into hydrogen for electricity generation, and discusses direct ammonia-fueled engines. It names the Wärtsilä 25 as a commercially available four-stroke ammonia engine as of late 2023, and says MAN Energy Solutions was developing a two-stroke model with a target of over 90% lower greenhouse-gas emissions than fuel oil. It also reports plans for the Yara Eyde ammonia-powered container ship, then expected for mid-2026, and a bunkering solution intended for its route between Norway and Germany. These are publication-era status and target statements, not confirmation of subsequent delivery or realized emissions reductions.
Cross-page status discrepancy: This article says Viking Energy is equipped with an ammonia fuel cell and has achieved a 30% emissions reduction. The related ShipFC article’s 30 Sep 2026 update says Viking Energy’s ammonia system did not proceed to full-scale onboard installation and the project concluded in 2025. The claims conflict; the ShipFC update is the more recent explicit status.
