The South-East European Hydrogen Corridor (SEEHyC) initiative aims to establish a hydrogen interconnector linking high-potential hydrogen supply areas  in South-East Europe with expected high-demand clusters in the EU, primarily in South Germany and North Bohemia. Additionally, it will connect local suppliers and consumers along the corridor.
The project has been initiated by seven gas Transmission System Operators (TSOs): DESFA (Greece), Bulgartransgaz (Bulgaria), Transgaz (Romania), FGSZ (Hungary), eustream (Slovakia), NET4GAS (Czech Republic), and OGE (Germany).
The pipeline will span over 3,000 km, enabling the transmission of renewable and low-carbon hydrogen. According to the ongoing pre-feasibility study, the project aims to be operational by 2030, with a minimum transport capacity of up to 80 GWh of hydrogen per day, or approximately 0.8 million tonnes per year. More information is available on the SEEHyC website.
This project could significantly contribute to the REPowerEU target of importing 10 million tonnes of green hydrogen into the EU by 2030. The SEEHyC initiative is open to collaboration with hydrogen producers, large hydrogen consumers, and other gas infrastructure companies to facilitate the implementation of the hydrogen value chain in Central and South-East Europe.
