European Commission opens TEN-E application window for hydrogen, electrolyser, and CO2 infrastructure PCI and PMI status

Executive Summary

The European Commission launched a call for applications on June 25, 2026 under the TEN-E Regulation for energy infrastructure projects in the hydrogen, electrolyser, and CO2 categories seeking Project of Common Interest or Project of Mutual Interest status. Selection confers access to accelerated permitting, cross-border cost allocation, and eligibility for EU financing instruments.

Bottom Line

The open call places project developers in the hydrogen, electrolyser, and CO2 sectors at a formal decision point: applications not submitted within the call window are excluded from the sixth Union PCI and PMI list cycle. Designation determines access to accelerated permitting, ACER-coordinated cross-border cost allocation, and Connecting Europe Facility grant eligibility. Projects that do not carry PCI or PMI status compete for financing and permitting capacity on standard national terms.

Key Regulatory Signals

• Application Window Now Open: Project developers in the hydrogen, electrolyser, and CO2 infrastructure categories may now submit applications for PCI or PMI designation under the TEN-E Regulation. Designation is a prerequisite for accessing the regulatory and financing benefits the framework provides.
• Accelerated Permitting Is the Operational Prize: PCI and PMI status entitles designated projects to streamlined permitting under the TEN-E framework, including a 3.5-year permit-granting deadline and a single national competent authority contact point. Developers without designation face standard national permitting timelines, which are materially longer in most member states.
• Cross-Border Cost Allocation Becomes Available: Designated projects gain access to cross-border cost allocation decisions by national regulatory authorities coordinated through ACER. This mechanism allows infrastructure costs to be distributed across benefiting member states rather than borne entirely by the host country.
• EU Financing Eligibility Unlocked: PCI and PMI status is a formal eligibility condition for Connecting Europe Facility energy grants. Project developers that do not secure designation are excluded from this funding stream regardless of project merit.
• Hydrogen and CO2 Categories Reflect Fifth PCI List Priorities: The call targets the same infrastructure categories prioritized in the fifth Union list of PCIs adopted in November 2023, signaling continuity with the Commission's clean energy transition investment framework under the European Green Deal.

Regulatory Delta

- The fifth Union PCI list, adopted in November 2023, established hydrogen and CO2 networks as priority corridors; this call advances the sixth list cycle.

- For the first time across recent cycles, electrolyser infrastructure appears as a named standalone category alongside hydrogen transport and CO2 networks.

- The call aligns with the European Hydrogen Bank's ongoing auction rounds and the REPowerEU investment targets for domestic hydrogen production capacity.
