IHI and GE Vernova achieve milestone with 100% ammonia combustion in large-scale test

3/19/2026
  • IHI and GE Vernova 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.
  • Emissions levels are aligned with the companies’ development roadmap; IHI and GE Vernova are continuing testing with prototype combustors.
  • This project is expected to play a meaningful role in decarbonizing (the reduction of carbon emissions on a kilogram per megawatt hour basis) the energy sector by enabling reduced or zero CO₂ emissions during combustion

IHI Corp. and GE Vernova Inc. have successfully tested 100% ammonia combustion for GE Vernova’s F‑class gas turbines. Emissions levels achieved during the test align with the companies’ 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 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.”
