The real laboratory “HydroHub Fenne” for electricity-based hydrogen production with waste heat utilization shall be built and tested on an industrial scale at the Voelklingen-Fenne site in Saarland. Its aim is to reduce CO₂ emissions from the sectors involved.

The real laboratory shall be integrated into the power plant site Voelklingen-Fenne and is to enable, in particular, the provision of system services and sector coupling (electricity-heat-traffic) in an economic way. Against the background of the high system complexity of sector coupling, artificial intelligence will also be used to further optimize the economic operation of the Fenne site.
