Enagás has solidified its standing as a premier European operator in the decarbonization of maritime transport via the provision of liquefied natural gas (LNG bunkering). The quantity of LNG supplied as fuel by Enagás-managed facilities in 2023 reached 1,359 GWh, marking a more than fourfold increase compared to 2021 (300 GWh).

The increased utilization of LNG has enabled the prevention of over 74,000 tonnes of CO2 equivalent emissions, as well as virtually eliminating emissions of sulfur and nitrogen oxides (SOx and NOx), thereby enhancing air quality within port surroundings.

Enagás has enacted holistic measures by modifying its terminals and constructing supply barges through its subsidiary Scale Gas, establishing itself as the European operator boasting the highest combined loading capacity.

This advancement stems from the efficacy of public-private partnerships seen in projects like CORE LNGas hive and LNGhive2, jointly funded by the European Commission. Spearheaded by Puertos del Estado and overseen by Enagás, these endeavors have established an integrated, secure, and effective logistics framework for LNG fuel supply across the Iberian Peninsula.

The regasification terminal operated by Enagás in Barcelona is capable of facilitating direct bunkering operations (pipe to ship, PTS). Since the commencement of operations by the Haugesund Knutsen, a vessel jointly owned by Knutsen and Scale Gas, in Barcelona in early 2023, the terminal has also facilitated LNG fuel supply through small vessels (ship to ship, STS). Through bunkering operations at the Port of Barcelona, emissions equivalent to 63,000 tonnes of CO2 have already been prevented.

Following the initiation of operations of the Levante LNG vessel, jointly owned by Peninsula and Scale Gas, the volume loaded at the Enagás plant in Huelva during the first four months of 2024 surged by 82% compared to the total supply in 2023. This terminal facilitates LNG loading onto STS supply barges and is slated to soon commence PTS operations. Furthermore, Scale Gas is constructing a third LNG and BioLNG supply vessel, backed by the Spanish Government's support through Next Generation funds, which is set to primarily operate in the Canary Islands starting from 2026.

The Enagás terminal in Cartagena, a frontrunner in Europe for providing PTS services, will soon expand its offerings to include STS operations.

Apart from the three regasification terminals wholly owned by Enagás, the company's majority-owned terminals in Spain also offer bunkering services: El Musel in Gijón, Saggas in Sagunto, and BBG in Bilbao provide Truck to Ship (TTS) services, with BBG additionally offering PTS services.
