Overview
- Enagás presented the Public Participation Concept Plan at the Port of Bilbao with Basque and Spanish energy leaders in attendance, including Lehendakari Imanol Pradales and Energy Secretary Joan Groizard.
 - The proposed route totals 163 kilometers, with roughly half in Bizkaia and about 30 kilometers each in Álava and Gipuzkoa.
 - The corridor would enter from Cantabria at the Port of Bilbao and run via Elorrio, Mondragón, and the Deba valley to Naclares in Álava, continuing through Armiñón to Haro in Rioja Alavesa.
 - Initial connections in Gipuzkoa target seven Alto Deba municipalities, with a potential second-phase link via Irun noted in the plan.
 - The process now moves into public participation and permitting before detailed engineering, with the line described as part of a wider Iberian network to channel hydrogen toward Europe.
