Spain's energy operator Enagás has officially launched the public participation plan for the country's ambitious hydrogen backbone network, a sprawling infrastructure project poised to become Europe's largest of its kind.

Unveiled at the National Hydrogen Centre in Puertollano, Castilla-La Mancha, the announcement marks a pivotal moment in Spain's strategy to position itself as a leading continental hydrogen hub.

The proposed network will span 2,600 kilometers, reaching 13 autonomous communities and connecting more than 550 municipalities across Spain. 

Recognized by the European Union as a Project of Common Interest (PCI), the hydrogen backbone has already secured over 75 million euros ($80.5 million) through the EU's Connecting Europe Facility. 

This substantial backing underscores Brussels' view of Spain's potential to anchor Europe's future hydrogen economy, linking renewable energy sources in Iberia with industrial demand centers further north.

According to Enagás, a significant portion of the infrastructure will utilize converted natural gas pipelines, a method expected to accelerate deployment and reduce costs while minimizing environmental impact compared to building entirely new lines.

Last week, during the launch of the public consultation related to the massive hydrogen project, Arturo Gonzalo, CEO of Enagas, said the project was advancing ahead of schedule in Spain, adding that it could be operational by 2030. 

"The project is starting to become a reality, it is progressing at a very good pace, even faster than expected," he said last Friday.

"Today, we are setting in motion a key milestone to make a hydrogen infrastructure a reality in Spain."

Currently, Enagás is moving forward with engineering studies for critical components such as compression stations, valve points, and necessary safety upgrades to ensure reliable network operations upon completion.

The final investment decision is anticipated in 2027, with the construction work beginning in 2028. The finished network will feature five primary corridors, including strategic routes like the Vía de la Plata and the Ebro Valley.

Additionally, it will integrate with the cross-border H2Med corridor, establishing direct hydrogen links between Spain, Portugal, and France and solidifying Spain's role as a vital energy bridge for Europe.
