The global shift towards net zero emissions demands innovative solutions in energy production. One breakthrough tackling this challenge is the successful combustion of 100% ammonia in F-class gas turbines, thanks to a pioneering test by GE Vernova and IHI Corporation. This advance has the potential to redefine hydrogen-compatible power generation and decarbonize existing gas-fired power plants—without sacrificing efficiency or performance.

Why Ammonia is Key for a Sustainable Energy Future

Ammonia (NH₃) stands out as a promising hydrogen carrier due to its high energy density, established transport infrastructure, and carbon-free combustion. As the global energy sector races to limit greenhouse gas emissions, research from the International Energy Agency indicates that ammonia could be a significant player in the clean energy transition—if its combustion challenges can be overcome.

Unlike traditional fossil fuels, burning ammonia does not directly release carbon dioxide. This means repurposing existing gas turbines to run on ammonia could accelerate decarbonization while utilizing reliable and scalable infrastructure already in place.

Inside the Landmark 100% Ammonia Combustion Test

On May 21, 2024, GE Vernova and Japan’s IHI achieved a first for the power generation industry: an F-class gas turbine combustor operating exclusively on ammonia for a sustained period. Testing took place at GE Vernova’s Gas Turbine Technology Center in Greenville, South Carolina, using a modified DLN 2.6+ combustor designed to optimize ammonia flames and minimize emissions.

• Fuel Flexibility: The system was engineered to switch between 50% hydrogen / 50% ammonia and 100% ammonia on demand, showcasing operational versatility for future plant hybridization.
• Emissions Control: The technology demonstrated ultra-low nitrous oxide (N₂O) emissions, a critical achievement given ammonia combustion’s known challenge with nitrogen-based byproducts.
• Scalability: The test validated both performance and practical considerations for deploying such technology in commercial F-class turbines worldwide.

These results are significant, as it’s the first time an F-class combustor has been proven to run exclusively on ammonia—a step beyond previous lab-scale demonstrations or lower firing percentage tests. For utilities aiming for net zero carbon goals, this opens a new pathway for low-carbon retrofits and clean energy generation.

What This Means for the Gas Power Industry

Historically, the decarbonization of gas turbines has hinged on costly equipment upgrades or fuel blending. Now, with this new approach, existing gas-fired plants may be retrofitted to burn clean ammonia, leveraging millions in legacy infrastructure while dramatically lowering their carbon footprint.

• Retrofitting Opportunities: Lower-cost upgrades allow utilities to remain competitive in a carbon-regulated market.
• Increased Reliability: High-efficiency, advanced-class turbines could maintain grid stability as intermittent renewables grow.
• Hydrogen Synergy: Ammonia provides a practical means of storing and shipping hydrogen, further supporting green hydrogen adoption in power generation.

This technological leap could hasten the arrival of “fuel-flexible” power plants, where operators switch seamlessly between natural gas, hydrogen, or ammonia based on market prices and carbon regulations—providing both sustainability and resilience.

Challenges & Next Steps for Ammonia-Based Clean Power

Despite this major milestone, several hurdles remain before 100% ammonia-fired turbines become mainstream:

• Ammonia Supply Chain: Scaling up green ammonia production is essential for true net zero benefits.
• NOx Emissions: Continued R&D is needed to address nitrogen oxide emissions at larger operational scales.
• Regulatory and Market Incentives: Supportive policies and carbon pricing mechanisms will be required to drive adoption.

GE Vernova and IHI report that their ultimate goal is to commercialize this solution for global markets—enabling utilities to deploy clean ammonia as either a primary or backup fuel for grid power or grid stability applications.
