Greece's Bold Energy Shift: 240 Hydrogen Projects and Gas Pipeline Upgrades Underway
Greece is rapidly expanding its energy infrastructure with a surge in hydrogen and natural gas projects. Over 240 hydrogen initiatives are now part of the country's long-term plans, alongside upgrades to existing gas pipelines. These developments aim to boost capacity and connect key regions across southeastern Europe. The Trans Adriatic Pipeline (TAP) will see its annual capacity rise to 14.2 billion cubic metres. This expansion supports Greece's broader energy strategy, which includes integrating hydrogen into its network.
A total of 345 projects feature in ENTSO-G's latest development plan, with 243 focused on hydrogen systems. Among these, 12 Greek initiatives align with national infrastructure goals. Key examples include the Helleniq green hydrogen plant in Thessaloniki, set to open in 2025, and DESFA's pipeline expansions linking Crete and Cyprus.
The H2L SE MED Reception Facility will connect to Greece's national system between 2028 and 2035. Meanwhile, DESFA plans to transport 0.9 million tons of hydrogen yearly through its interconnections. The H2DRIA project will link production sites in Greece with demand centres in Athens, Corinth, Thessaloniki, and neighbouring countries like Bulgaria and Italy.
Several major projects have clear timelines. The Cretan H2 Hub, led by Eunice, is due to begin operations in 2032. That same year, a hydrogen interconnection between Bulgaria and Greece will launch. The Thalis 1 electrolyzer facility will follow in 2032, with its connection to DESFA's H2DRIA pipeline completed by 2040.
Natural gas infrastructure is also advancing. The EastMed and Poseidon pipelines will go live in 2029, with hydrogen capabilities added by 2034. The high number of hydrogen projects signals increasing investment and coordination among stakeholders. With phased rollouts from 2025 to 2040, Greece's energy network is set to become more interconnected and sustainable. These upgrades will support both domestic and cross-border energy demands.
