The Conceptual Public Participation Plan (PCPP) will run until March 27 through information points in each of the region’s 39 municipalities to gather opinions and views on the project.

The PCPP will ultimately produce a final report incorporating the social and environmental solutions raised.

Enagás also plans to hold eight one-day participatory seminars, educating the public on the backbone network.

The consultation comes after a similar informational initiative launched last year in the Extremadura region.

Enagás is leading the development of four key infrastructure projects across the country, including the hydrogen backbone, linking the Iberian Peninsula to Central Europe. It could amount to 2,700km of pipeline networks.

The European Commission has labelled these as Projects of Common Interest (PCI) and approved €75.8m ($85.8m) in Connecting Europe Facility (CEF) funding for their study phase in January 2025.

“The hydrogen economy will generate more than €32 billion of GDP in Spain and support some 81,000 jobs during the development of the Backbone Network”, according to Enagás.
