GE Vernova, IHI Achieve 100% Ammonia Combustion in F-Class Gas Turbine Test

Why It Matters

Achieving 100 % ammonia combustion removes a critical technical hurdle, opening a pathway for low‑carbon, dispatchable power and large‑scale turbine retrofits. It positions GE and IHI to capture emerging market demand driven by policy incentives in Japan and South Korea.

Key Takeaways

• 100% ammonia combustion achieved in GE F‑class turbine test
• Commercial rollout targeted for 2030, pending NOx data
• Ammonia offers carbon‑free fuel with existing global logistics
• Japan’s policy drives demand for ammonia‑fueled power
• Retrofit potential could unlock decarbonization for 7,000 GE turbines

Pulse Analysis

Ammonia is gaining traction as a carbon‑free fuel because it leverages an existing global supply chain that moves roughly 10 % of world production annually. Unlike liquid hydrogen, it only requires modest cooling to –33 °C, allowing it to be stored and shipped using current port infrastructure. These logistical advantages, combined with its zero‑carbon combustion profile, make ammonia an attractive bridge for regions lacking sufficient renewable capacity, especially Japan and South Korea, where policy frameworks actively promote hydrogen carriers.

The 100 % ammonia combustion test at IHI’s Aioi Works facility validates a core technical challenge: stable, full‑load operation of a heavy‑duty F‑class turbine on pure ammonia. While the companies withheld NOx and efficiency figures, the successful demonstration suggests that combustion stability, ignition, and material compatibility can be managed at scale. For GE Vernova, this breakthrough unlocks a retrofit market for its installed base of about 7,000 turbines, potentially converting existing gas‑fired assets to low‑carbon operation without new capital‑intensive builds.

Policy momentum is accelerating the commercial case. Japan’s Seventh Strategic Energy Plan, finalized in 2025, earmarks ammonia for co‑firing and eventual 100 % use, backed by supply contracts for hundreds of thousands of tonnes of low‑carbon ammonia. Parallel efforts by Mitsubishi Power and other OEMs signal a broader industry shift toward ammonia‑ready turbines. As regulators clarify NOx limits and SCR technologies mature, the pathway to a 2030 market launch appears increasingly viable, positioning GE and IHI at the forefront of the emerging ammonia‑fuel ecosystem.
