HYFLEXPOWER consortium operates 100% renewable hydrogen gas turbine

Global Hydrogen Review,
The hydrogen is produced by an 1 MW electrolyser on-site, and then stored in an almost one-ton tank and used to power a Siemens Energy SGT-400 industrial gas turbine.
The HYFLEXPOWER project demonstrates that hydrogen can be used as a flexible energy storage medium, and that it is also possible to convert an existing gas-fired power turbine to operate using renewable hydrogen. It is therefore a real driver for accelerating the decarbonisation of energy-intensive industries.
In 2022, an initial series of tests enabled the industrial gas turbine to operate with a 30% hydrogen content, mixed with natural gas. Now the power-to-hydrogen-to-power demonstrator has proven that turbines with dry low emissions technology can be fuelled with up to 100% hydrogen, as well as with natural gas and any blends in between.
The HYFLEXPOWER consortium includes Siemens Energy, ENGIE via its subsidiary ENGIE Solutions, Centrax, Arttic, the German Aerospace Center (DLR), and four European universities.
As the consortium lead, Siemens Energy supplied the electrolyser for hydrogen production and developed the hydrogen gas turbine. ENGIE built the hydrogen production, storage and supply for the demonstrator. Centrax were responsible for the package upgrade to ensure safe operation with hydrogen fuel. The German Aerospace Center (DLR) and the Universities of Lund (Sweden), Duisburg-Essen (Germany), and University College London (UK) contributed to the hydrogen turbine technology development. Arttic supported the operational project management, while NTUA in Athens (Greece) carried out economic, environmental, and social analysis of the concept.
Building on the promise of the HYFLEXPOWER demonstrator, it is planned to expand the consortium to include additional members. Having tested HYFLEXPOWER for electricity production, the goal is now to extend its operation to industrial heat production and additional operational modes. It is also planned to explore ways of scaling up and commercialising decarbonised electricity generation.
