The Interreg project is based on existing hydrogen (H₂) activities in the Lake Constance–Alpine Rhine region. It brings together relevant organisations from different countries to establish a hydrogen ecosystem through three key areas of focus.

The core elements of the project are:

1. Cross-border H₂ applications: The project focuses on the use of hydrogen in shipping, freight transport and industry.

2. Cross-border H₂ trade: When H₂ is traded across borders via pipelines and trailers, the H₂ itself must be tradable, as must the certificates of origin to demonstrate its renewable status. The project will identify regulatory and technical barriers.

3. Cross-border H₂ network: Initial feasibility studies are being carried out for a potential hydrogen network in the Lake Constance–Alpine Rhine region. Building on the existing gas network, this will be repurposed and/or supplemented by new H₂ pipelines.

A total of 12 partners and 17 associated partners are involved in the Interreg project.
