The pre-feasibility study for the Czech-German Hydrogen Interconnector (CGHI) has been successfully completed, marking a significant milestone in the development of this critical hydrogen transport corridor. Jointly prepared by GASCADE, NET4GAS, and OGE, this study provides a high-level analysis of the project’s technical and commercial feasibility, reflecting data and assumptions as of October 31, 2024.

The CGHI aligns with the European Hydrogen Backbone (EHB) and the EU’s REPowerEU strategy, creating a vital link between hydrogen production centres in Northern and Baltic regions and major demand hubs in southern Germany. Spanning 772 km from Lubmin via cross-border point Deutschneudorf and Waidhaus to South Germany, the corridor will primarily use repurposed existing gas infrastructure (approx. 87 %), supplemented by new pipelines with operations projected to begin by 2029 and compressor stations to be added at a later stage.

Key findings from the study underscore the technical viability of converting existing infrastructure for hydrogen transport, though certain upgrades—such as valve replacements and modifications to gas pressure regulation equipment—will be required. Initial transport capacity is estimated up to 144 GWh per day, sufficient to supply hydrogen to the Czech Republic and support Germany’s growing hydrogen demand, expected to rise up to 130 TWh by 2030 and up to 500 TWh by 2050.

The project demonstrates high cost-efficiency, with CAPEX estimated at €986.3 million (±13 %), 30% below the EHB benchmark, and annual OPEX projected at €30 million (±7 %). Financing strategies include private investments supported by state-backed guarantees in Germany and a mix of EU and national funding in Czechia.

Next steps involve maintaining the PCI/PMI status, conducting detailed national feasibility studies, and preparing for the final investment decision over the next years. While significant challenges remain, the study highlights the corridor’s potential to advance Europe’s hydrogen economy, supporting energy transition goals and regional decarbonization.
