Project description

As part of the „H2 GeNeSiS“ flagship project, the Stuttgart model region aims to build a hydrogen pipeline along the Neckar river as a basis for scaling up the hydrogen economy in the Stuttgart region. Both producers and users will connect themselves to the pipeline, thus developing a far-reaching distribution network.

As part of this flagship project, Stadtwerke Stuttgart GmbH is implementing a plant for the production, storage and feed-in of regeneratively produced hydrogen into a pipeline as well as parallel utilization by means of a trailer filling plant. The hydrogen produced is thus used both by local industry and the mobility sector. The plants are to be operated in line with the grid and thus contribute to the flexibility of grid operation.

The aim of the project is to build a process plant for the primary production of hydrogen that is cost-optimized over its entire life cycle. During planning, the focus is not only on construction costs, but also on high availability, high efficiency and low operating costs.

Containerized electrolysis systems with an output of 10 MW and 180 kg H2/h will be used. The hydrogen obtained will have a quality of at least 4.0. The electrolysers supply an H2 pipeline and a loading storage for H2 truck trailers. The heat released from the process will be used to heat a nearby property.
