MITECO to process the first segments of the hydrogen backbone network in Spain

Global Hydrogen Review,

MITECO has begun processing the first segments of Spain’s renewable hydrogen backbone network, developed by Enagás. These infrastructures, considered Projects of Common European Interest (PCI), will require an investment of €389 million and are linked to three significant projects in Andalusia, Aragon, and the Basque Country. 

All three have received public funding and are considered to be key drivers of economic activity, bringing together hydrogen producers and consumers who are ready to make investment decisions.

These pipelines of the future network are being processed under the expedited procedure:

  • The Onuba electrolyser project in Huelva, with a capacity of 300 MW, has received €303.75 million in aid from the Recovery Transformation and Resilience Plan (PRTR). It has requested the acceleration of the Huelva-Aznalcázar segment, part of the Huelva-Almendralejo section of the future grid, which is 59 km long and requires an investment of €95.7 million.
  • The Catalina electrolysis plant project in Teruel, with a capacity of 500 MW, has been awarded €245 million from the Regional Electricity Transmission Network (PRTR) and has requested priority for two pipelines of the future grid. The first, between Caspe and Tivissa, is 75 km long and requires an investment of €98.6 million. The second, between Tivissa and the Tarragona Industrial Park, is 62 km long and requires an investment of €126.5 million. Both are part of the Zaragoza-Tivissa section.
  • Finally, the Petronor electrolyser project in Vizcaya, with a capacity of 100 MW, has received €160 million from the PRTR and plans to expedite the 38 km Muskiz-Arrigorriaga segment, linked to an investment of €68 million, which is part of the Reocín-Arrigorriaga section.

The pipelines are part of the H2Med corridor, which will connect the Iberian Peninsula with Central Europe, and their processing is being expedited, thus halving the procedural timeframes. All of them must undergo their own environmental impact assessment - meaning the public consultation period will not be shortened here - and construction is expected to last from eight months to a year, depending on the project.

Without regulated remuneration from the gas system

The processing of these sections is to be carried out under the Additional Provision 38 of Law 34/1998 of the hydrocarbons sector. Therefore, they will initially have negotiated access rights and will not accrue regulated remuneration from the gas system. Subsequently, their economic and access framework will be adapted to the regulations established after the transposition of the European package relating to renewable gas, natural gas, and hydrogen markets.

It is expected that Enagás will soon request administrative authorisation for all the sections that will constitute the future renewable hydrogen backbone network: Mérida-Salamanca, Salamanca-León, León-Llanera, Llanera-Reocín, Arrigorriaga-Haro, Haro-Zaragoza, Tivissa-Salzadella, Salzadella-Paterna, Paterna-Montesa, Montesa-Cartagena, and Almendralejo-Puertollano.

The Government has awarded more than €3 billion to 124 renewable hydrogen projects under the PRTR.
