FLEXnCONFU - FLEXibilize combined cycle power plant through Power-to-X solutions using CONventional fuels is a research project funded by Horizon2020 EU’s research and innovation programme (GA 884157), with the goal to develop and demonstrate innovative, economically viable and replicable Power-to-X-to-Power (P2X2P) solutions that combines all available options for the effective and flexible use of surplus power from renewable energies to leveling the power plant load convert electricity into hydrogen or ammonia prior to converting it back to power. This will enable the design and operation of an integrated power plant layout that can un-tap additional Combined Cycle plants flexibility.
