FLEX4H2, coordinated by Ansaldo Energia, won the 'Best Success Story' award at the Hydrogen Research and Innovation Days 2025 for its advancements in hydrogen combustion. The project showcased the effectiveness of sequential combustion in using various blends of natural gas and hydrogen, aiming for turbines to operate with up to 70% hydrogen by 2030, thereby enhancing decarbonization in power generation. This technology, based on Constant Pressure Sequential Combustion (CPSC), improves fuel flexibility and reduces emissions.
