• IHI and GE Vernova have successfully demonstrated the combustion of 100% ammonia using full-scale equipment under pressure, temperature, and flow conditions equivalent to full-load operation of GE Vernova’s F-class gas turbines.
• The emissions recorded during testing are consistent with the companies’ development roadmap, and both partners continue further validation using prototype combustor technologies.
• This project is expected to contribute significantly to energy sector decarbonization* by enabling combustion processes with minimal or zero CO₂ emissions.

TOKYO, JAPAN – ATLANTA, GA (March 18, 2026) – IHI Corporation (IHI) and GE Vernova Inc. (NYSE: GEV) announced the successful completion of a test involving 100% ammonia combustion in GE Vernova’s F-class gas turbines. The emission performance achieved aligns with their long-term development strategy aimed at delivering a fully ammonia-fueled gas turbine, with commercial deployment targeted by 2030.

“An important part of the ammonia value chain is now being realized,” said Noriaki Ozawa, Managing Executive Officer and President of the Resource, Energy & Environment Business Area at IHI. “Since entering into our joint development agreement in 2024, collaboration between our teams has accelerated significantly, and we are now seeing tangible results. Achieving full-scale ammonia combustion in an F-class gas turbine represents a key milestone and supports our customers’ decarbonization strategies in the power sector.”

The test was carried out at a специально designed IHI facility, built to replicate the real operating environment of GE Vernova’s F-class turbines.

“The ability to operate an F-class gas turbine entirely on ammonia fuel is a major step toward a lower-carbon energy future,” said Jeremee Wetherby, Carbon Solutions leader at GE Vernova. “This milestone validates our roadmap and highlights the strength of our partnership with IHI. We believe ammonia has strong potential as a carbon-free fuel, and we remain committed to advancing its role in global decarbonization efforts.”

Ammonia is already widely used in industrial sectors, particularly in fertilizer production. As a hydrogen carrier, it offers a more efficient and cost-effective solution for transportation and storage. Additionally, ammonia is expected to play a growing role in power generation as a carbon-free fuel. Because it contains no carbon, its combustion does not directly produce CO₂, making it a promising option for reducing emissions in the energy sector. (Note: even when using carbon-free fuels, trace CO₂ emissions may occur due to the presence of carbon dioxide in ambient air.)
