Ansaldo Energia and partners have kicked off the FLEX4H2, a four-year project to design, develop, and validate a highly fuel-flexible gas turbine combustion system based on Ansaldo’s sequential combustion technology that will be capable of operating with up to 100% hydrogen.
The FLEX4H2 (or Flexibility for Hydrogen) officially began on Jan. 1 and will run until December 2026. During that time, the €8.7 million ($9.3 million) project’s nine partners will explore challenging conditions associated with hydrogen combustion, including H-class operating temperatures, which are “required for highest cycle efficiency, while still meeting emission targets without any use of diluents,” said Italian gas turbine manufacturer Ansaldo Energia on Feb. 9.
