Greece has an increasingly strong presence in the European liquefied natural gas market, combining maritime capacity with energy infrastructure. The Greek-owned LNG carrier fleet is estimated at roughly 135–170 vessels, representing about 22 percent of the global LNG fleet in dwt capacity. Its age profile is relatively young, as the average age of the Greek-owned fleet across all ship types is roughly 10 years, while LNG carriers are largely built within the last decade, mostly with capacities of 170–180 thousand cubic meters and equipped with modern propulsion and energy-efficiency systems. Companies active in the sector include Maran Gas, Capital Gas, GasLog, Dynagas, Alpha Gas, Thenamaris and Latsco.
The United States has become a leading global LNG exporter, with a significant share of cargoes destined for Europe. Greek-owned vessels form a critical link in transporting U.S. LNG to European markets, regularly serving routes from terminals on the U.S. Gulf Coast. The surge in global LNG demand after 2022 strengthened the role of Greek shipping companies in this transport chain.
In parallel, Greece has operational import and regasification infrastructure. The Revythoussa terminal remains a key hub for the domestic market and for re-exports, while since October 2024 the Alexandroupolis FSRU has been in full commercial operation, with regasification capacity of up to 5.5 billion cubic meters per year. Its operation has reinforced supply routes toward the Balkans, making use of existing and new interconnections.
The increased use of the Greek system is reflected in 2025 data, which show rising natural gas demand and a significant increase in exports through the national grid. LNG now accounts for more than 40 percent of the country’s natural gas imports, with the United States serving as the main supplier of cargoes. The ability to re-export has expanded, allowing volumes to be directed to markets in Southern and Eastern Europe.
Greece participates in the Vertical Corridor, a cooperative framework with Bulgaria, Romania, Hungary, Slovakia and other regional countries, aimed at strengthening regional energy security. The reverse flow of the Trans-Balkan pipeline and new transport capabilities make it possible to forward gas from Greece to the Balkans and Central Europe. Within this framework, 2025 saw shipments of U.S.-origin LNG to Ukraine through Greek infrastructure.
Regarding new projects, additional facilities are under examination, such as the FSRU in Corinth, which is currently undergoing business and regulatory assessments. The completion of new terminals could further enhance system flexibility and regasification adequacy.
The combined presence of a strong Greek-owned LNG fleet, upgraded infrastructure, and close cooperation with the United States forms a stable framework for LNG flows to Europe. The country acts as a hub for reception, storage, regasification and transit, while Greek shipping covers a significant share of LNG transport from the United States to European terminals, supporting supply security and energy diversification in the region.
