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

IHI Corp. (IHI) and GE Vernova have successfully demonstrated 100% ammonia combustion in GE Vernova’s F-class gas turbines, marking a significant step toward carbon-free power generation. The test results aligned with both companies’ roadmap for developing a fully ammonia-fueled gas turbine, targeting commercial deployment by 2030. The demonstration took place at IHI’s specialized test facility, designed to replicate the operating conditions of GE Vernova’s F-class turbines.

“An essential piece of the ammonia value chain is now coming into place,” said Noriaki Ozawa, IHI Managing Executive Officer and President of the Resource, Energy, and 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.”

Ammonia, widely used in industrial processes such as fertilizer production, is gaining attention as an energy carrier. When paired with hydrogen, it offers a lower-cost, more efficient option for transport and storage. In power generation, ammonia can burn without producing CO₂, supporting the sector’s efforts to reduce emissions. Any air-based combustion, even if operating on a carbon-free fuel, will emit a trace amount of CO₂ based on the concentration of CO₂ in the atmosphere.

“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.”

Process Gas Compressor

In February 2026, IHI Corp. and IHI Rotating Machinery Engineering (IRM) executed a successful demonstration test for a new process gas compressor using CO₂ as the working fluid, achieving a maximum discharge pressure of 20MPaG. The test deployed a turbo-type unit featuring a geared, multi-shaft, multi-stage configuration with multiple pinion shafts driven by an internal gear system.

A successful outcome enables the injection of supercritical CO₂ into deep geological formations, like deep saline aquifers, to advance commercial carbon capture, utilization, and storage (CCUS) and progress industrial decarbonization. Unlike single-shaft, multi-stage compressors where all impellers rotate at the same speed, the geared architecture enables stage-by-stage optimization of impeller speeds, improving energy efficiency and space efficiency.

With this milestone demonstration, IHI and IRM will expand the application of their compression technologies to processes with high decarbonization potential, establish core capabilities across the CCUS value chain, and further improve system reliability. The IHI Group will help reduce environmental impact and expand decarbonization-based infrastructure, contributing to a sustainable and low-carbon society.

Terry Bundy Station

Also in February,Lincoln Electric System granted GE Vernova a contract to deliver two LM6000VELOX aeroderivative gas turbine packages for its Terry Bundy Generating Station (TBGS) in Lincoln, NE. The units may expand TBGS’s power output by approximately 100 MW, helping to fulfill Nebraska’s growing electricity demand driven by population growth and expanding residential and commercial requirements.
