Spain allocates hydrogen grid capacity as blending rollout begins

HYDROGEN will make up 2% of Spain’s gas supply after grid operator Enagás awarded network capacity to 35 renewable hydrogen projects.

The allocation represents 900 MW of electrolyser capacity annually, 7.4% of the first-phase target set in Spain’s Integrated National Energy and Climate Plan (PNIEC).

The move aligns with the EU’s Hydrogen and Decarbonized Gas Market Package, which permits hydrogen blending of up to 2% in gas networks to avoid gas-quality mismatches and protect downstream users.

To support the rollout, Enagás is progressing its US$3bn Spanish Hydrogen Backbone Network which will include 2,600 km of underground hydrogen pipelines linking Spain’s main industrial centres and hydrogen production hubs.

Enagás expansion

As part of the company’s backbone plan, Enagás has launched its Conceptual Public Participation Plan (PCPP), which it described as the largest public consultation on energy infrastructure in Spain, covering 13 autonomous communities and more than 500 municipalities.

Enagás has also opened a market call for interest aimed at hydrogen producers and industrial consumers as it advances development of the backbone network.

The consultation process is already under way in Catalonia, where 275 km of hydrogen pipelines are planned.
