On March 13th, 2026, Iñigo Muñoz Mateos, researcher from Tecnalia, presented a groundbreaking methodology for the identification and configuration of Hydrogen (H2) Valleys at the European Hydrogen Energy Conference (EHEC) 2026. The presentation, titled “Methodology for the identification and configuration of H2 valleys,” acknowledged the project and it was aligned with the EU’s climate-neutral strategy, specifically addressing the Renewable Energy Directive and REPowerEU targets, which aim for 10 million tonnes of renewable hydrogen production by 2030.

Muñoz outlined a comprehensive four-step methodology designed to streamline the deployment of these integrated hydrogen ecosystems:

  • Step 1: Potential location identification.
  • Step 2: Renewable assessment potential and technology selection.
  • Step 3: Power-to-X (P2X) system sizing.
  • Step 4: Detailed technoeconomic assessment.

A key element of the presentation was the comparison between Green H2 (produced from 100% renewable sources) and Low Carbon H2 (achieving a 70% life-cycle GHG reduction compared to fossil H2). Using a 10 MW alkaline electrolyzer as a baseline, the study analysed seven different electricity supply configurations, ranging from direct local renewable connections to grid-only supply.
