Georgian officials have now indicated that a parallel green hydrogen pipeline is under consideration, potentially expanding the strategic scope of the Green Energy Corridor and positioning the region as a future exporter of both renewable electricity and low-carbon fuels.
Speaking during Baku Energy Week, Deputy Minister of Economy and Sustainable Development Inga Pkhaladze said Georgia is examining the possibility of constructing a green hydrogen pipeline alongside the planned Black Sea submarine power cable. While still at a preliminary stage, the proposal reflects a broader shift in European energy planning as governments seek multiple pathways to decarbonize hard-to-abate sectors while strengthening energy security.
The hydrogen concept emerges as the European Union continues to pursue ambitious targets for renewable hydrogen deployment. However, progress across the continent has been slower than initially anticipated. High production costs, limited infrastructure, uncertain demand growth, and delays in final investment decisions have created significant challenges for large-scale hydrogen development. Against this backdrop, transport infrastructure capable of linking regions with abundant renewable resources to future demand centers has become a critical component of long-term energy strategies.
Georgia’s interest in integrating hydrogen into the Green Energy Corridor highlights the country’s growing role as an energy transit hub between the Caspian region and Europe. The corridor already includes two major transmission routes. One is a land-based connection running from Azerbaijan through Georgia toward Turkey and Bulgaria. The second is the planned submarine electricity cable connecting Azerbaijan, Georgia, Romania, and Hungary across the Black Sea.
The submarine cable remains the centerpiece of the initiative. Designed with a transmission capacity of 4,000 megawatts, the project aims to enable renewable electricity exports from the South Caucasus to European markets. Such capacity would represent a meaningful addition to regional cross-border electricity infrastructure, particularly as Europe seeks greater diversification of energy supplies following years of geopolitical disruption in traditional energy markets.
Yet the emergence of hydrogen discussions reflects a recognition that electricity transmission alone may not fully capture the economic potential of expanding renewable generation capacity in the region. Renewable electricity can be transmitted directly through power lines, but hydrogen offers an alternative pathway for storing and transporting energy over long distances, particularly for industrial sectors where direct electrification remains difficult.
The economic case for a parallel hydrogen pipeline, however, remains subject to significant uncertainties. Green hydrogen production requires large volumes of low-cost renewable electricity, and many projects globally continue to face challenges achieving cost competitiveness against conventional hydrogen production methods. Infrastructure costs present an additional hurdle. Building dedicated hydrogen transport networks requires substantial investment, while future utilization rates remain difficult to forecast given the still-developing nature of hydrogen demand.
For Georgia and Azerbaijan, the opportunity lies in leveraging their renewable energy potential and existing position within regional energy trade networks. Azerbaijan has accelerated renewable energy development plans in recent years, while Georgia’s hydropower resources provide a foundation for low-carbon electricity generation. If renewable capacity expands significantly, hydrogen production could become an additional export pathway alongside electricity exports.
Pkhaladze emphasized that energy security remains Georgia’s primary objective and that achieving it requires regional cooperation rather than isolated national strategies. The Green Energy Corridor reflects that approach, bringing together Georgia, Azerbaijan, Romania, Hungary, and other European partners in a framework designed to strengthen interconnected energy systems.
The emphasis on regional integration also reflects broader lessons from recent energy market volatility. Cross-border infrastructure projects can improve resilience by diversifying supply routes and creating alternative channels for energy trade. However, they also require complex coordination among multiple governments, regulators, transmission operators, and investors, often extending project timelines and increasing execution risks.
Whether a hydrogen pipeline ultimately becomes part of the Black Sea corridor will depend on future demand projections, policy support mechanisms, infrastructure economics, and the pace of renewable energy deployment across the region. For now, the proposal signals that policymakers increasingly view the corridor not merely as an electricity export route but as a broader platform for future low-carbon energy trade between the South Caucasus and Europe.
