Clean Hydrogen Coastline

The German North Sea coast is of particular importance in the development of a nationwide hydrogen economy. Due to the high supply of renewable energies, hydrogen can not only be produced in the region, but also stored, integrated into the energy system via existing electricity and gas infrastructure, or used directly on site. The "Important Project of Common European Interest" (IPCEI) "Clean Hydrogen Coastline" is intended to contribute to the development and expansion of the hydrogen economy in the Northwest region.

In the IPCEI "Clean Hydrogen Coastline", the industry partners ArcelorMittal, EWE, Faun, Gasunie, swb and Tennet want to build 400 megawatts of electrolysis capacity in the Northwest region by 2026. To this end, there are various projects to help with implementation.

For example, the hydrogen generated by offshore electricity will be used, among other things, for climate-neutral steel production at the Bremen steel site. If required, surplus hydrogen can be temporarily stored by connecting it to the cavern storage facility in Huntorf.

Clean Hydrogen Coastline's many links, for example with the Dutch partners, but also with projects in Hamburg and North Rhine-Westphalia, offer extensive potential for a European IPCEI. This will enable the partners to take a decisive step towards becoming an important building block of a future European hydrogen economy. The main goal of the project is to Integration of hydrogen into existing energy infrastructures.
