Mainzer Stadtwerke and Kraftwerke plans hydrogen infrastructure in Mainz

Both partners want to produce, transport and process green hydrogen in Mainz to support decarbonisation.

Mainzer Stadtwerke AG (a utility service provider) and Kraftwerke Mainz-Wiesbaden AG (an energy company) are planning to develop a new grid infrastructure in Mainz, Germany H2 Bulletin reports.

The plan is to produce, transport and process hydrogen. Subject to the funding, the work on the project can be started next year and operation starting 2027. The KMW plans to install a 25 MW electrolyser to produce hydrogen for methanol. The plant will use around 16k tonnes/year CO2 from the exhaust gas flow of its waste-to-energy plant. The hydrogen will also be supplied for industrial use, transport sector and grids in Mainz.

Dr Tobias Brosze, Technical Director of Mainzer Stadtwerke Ag said that there is also a plan for building a hydrogen filling station. He further added, “The network infrastructure will make a decisive contribution to decarbonising the industrial and heavy goods transport sectors in Mainz and the Rhine-Main region, i.e. implementing less carbon.”

The project is subject to funding from the ministry of energy and also applied for the EU’s Important Projects of Common European Interest (IPCEI) funding, where the decision is expected by the end of 2021.

The mayor of Mainz and chairman of the supervisory board of Stadtwerke, Michael Ebling, said that the federal and EU governments would be able to support the Mainz project accordingly and thus start implementation as early as next year.
