IHI and GE Vernova announced they have successfully demonstrated combustion of 100% ammonia using full-scale components at pressures, temperatures and flows matching full-load conditions for GE Vernova’s F-Class gas turbines.

The companies also said emission levels achieved during the test align with their development roadmap towards the goal of a 100% ammonia-fired gas turbine, with the aim of achieving commercial deployment by 2030.

“An essential piece of the ammonia value chain is now coming into place,” said Noriaki Ozawa, IHI Managing Executive Officer and President of Resource, Energy & Environment Business Area. “Since the signing of the joint development agreement in 2024, the collaboration between our two companies has gained strong momentum, with the efforts of both teams now bearing fruit. The successful achievement of 100% ammonia combustion in a full-scale F-class gas turbine marks a major milestone and helps reinforce the decarbonization roadmap envisioned by our customers in the power sector.”

The demonstration was conducted at IHI’s purpose-built test facility, engineered to replicate GE Vernova’s F-class gas turbine operating conditions. The test facility, located at IHI’s Aioi Works facility in Hyogo, Japan and completed last summer, was engineered to test advanced combustion systems at GE Vernova’s F-class gas turbine operating conditions, including pressure, temperature, and both air and fuel flow rates.

The collaboration between the two companies includes synergies across IHI ammonia combustion expertise and GE Vernova global technical teams, and shared best practices developed at GE Vernova’s advanced combustion test facility in Greenville, South Carolina.

Ammonia, a derivative from hydrogen, does not result in any net CO₂ emissions when combusted. Ammonia is used today in industrial applications, such as fertilizer. It is also used as a carrier of hydrogen.

“The successful demonstration of running an F‑class gas turbine on 100% ammonia fuel marks a pivotal step in our journey toward a lower‑carbon energy future,” said Jeremee Wetherby, GE Vernova’s Carbon Solutions leader. “This achievement reinforces our development roadmap and underscores the strength of our collaboration with IHI. We see significant potential for ammonia as a carbon‑free combustion fuel and are energized to continue working together to help unlock its role in advancing global decarbonization.”
