Imagine a giant power plant engine that usually burns natural gas. This project makes it so that same engine can switch to burning pure hydrogen without breaking or polluting. It's like upgrading a car engine to run on any mix of gas or hydrogen without needing a whole new vehicle.
Modern gas turbines struggle with hydrogen combustion due to flashback risks and emission limits. This prevents power plants from switching to carbon-free hydrogen fuels without replacing expensive hardware.
A Gen2 sequential combustion system featuring redesigned burners and fuel injectors. It includes full-size prototypes validated for 100% hydrogen operation.
If you are a plant operator dealing with strict carbon emission limits — this project developed a sequential combustion system that allows turbines to run on up to 100% hydrogen. This means you can decarbonize your energy production without replacing your entire turbine infrastructure.
If you are a manufacturer dealing with the need for greener products — this project developed a retrofittable combustor design. This allows you to offer refurbishment services to existing H-Class turbine owners to make their assets hydrogen-ready.
If you are a utility provider dealing with unstable renewable energy supply — this project developed a responsive power-on-demand system. It uses hydrogen as a reliable, weather-independent fuel to maintain high efficiency and power output.
Based on available project data, specific pricing is not provided, but the system is designed to be retrofittable to existing gas turbines, which typically reduces costs compared to full asset replacement.
The technology is based on the GT36 H-class engine (760 MW in combined cycle) and has been validated through scaled and full-size prototypes up to TRL6.
The project utilizes a proprietary combustion technology called constant pressure sequential combustion (CPSC). Based on available project data, specific licensing terms for the Gen2 improvements are not detailed.
Yes, the project is designed to meet all emission targets set by the Clean Hydrogen JU Strategic Research and Innovation Agenda (SRIA).
The project runs until 2026-12-31 and includes the development of a roadmap for deployment into operational power plant environments.
The consortium is heavily industry-driven with a 56% industry ratio, consisting of 5 industrial partners across 6 countries. Led by Ansaldo Energia SPA, the group combines the commercial weight of large enterprises with the technical expertise of 2 research centers and 1 university, ensuring the transition from lab testing to TRL6 industrial prototypes.
