The Week in Alt Fuels: Spain anchors Iberian biomethane push in International Shipping News 28/02/2026 A recent report by industry body Gasnam projects that the Iberian Peninsula could overtake the Netherlands as Europe’s leading bunkering hub for liquefied natural gas (LNG) and its low-emission variants like bio- and e-methane this year. “Iberia challenges the hegemony of the north of the continent,” Gasnam notes. The study says a key reason could be that most bunkering activity in the Netherlands is concentrated in the port of Rotterdam, while activity in Iberia is spread across a wider range of ports in Spain, Portugal and Gibraltar. This geographic spread is reinforced by the peninsula’s location at the western edge of continental Europe, linking the Mediterranean with the Atlantic Ocean and sitting at a key crossroads for shipping traffic between the Americas, Africa and the rest of Europe. LNG bunkering is widely established across Spain, with a range of ports offering physical deliveries of the fuel, including smaller locations such as Motril, Almeria, Denia, Tenerife and Valencia. Liquefied biomethane (LBM) bunkering has become more widespread in Spain. ENGINE’s analysis shows that physical LBM deliveries are available in several Spanish ports including Algeciras, Barcelona, Malaga, Cartagena, Bilbao, Huelva, Gijón and Vigo. In comparison, only a few of ports in Portugal, such as Porto, Sines and Leixoes, have seen LBM bunkering activity to date. On the infrastructure side, LBM bunkering in Spain benefits from a well-developed natural gas transmission grid. This can allow the region’s biomethane producers to move volumes for bunkering without physically delivering the fuel to ports, by injecting biomethane anywhere in the gas grid using a mass balance system. Suppliers can then withdraw it as certified green gas. In addition, a partnership between CycleØ and Nedgia has established private biomethane grid connections in Spain so that remote production sites can be directly connected to the national gas grid. Another advantage lies in the physical integration of ports and gas infrastructure. Several regasification terminals in Spain are located near ports, allowing fuel to be delivered directly to vessels from the terminals – although cargo ships will often get preference for terminal slots. For instance, Enagás operates seven regasification plants in Spain and all of them can perform for terminal-to-ship bunker operations. The facilities in Barcelona, Cartagena, Huelva and Gijón have already supplied LBM to ships. The Reganosa-owned Mugardos Energy Terminal in Galicia is also ready to supply LBM for bunkering, offering both truck-to-ship and terminal-to-ship deliveries. Bunkering readiness extends to vessel availability, with physical suppliers including Axpo, Titan/Molgas, Peninsula and Enagás deploying bunker vessels to deliver LNG and LBM across Spanish and wider Iberian ports. A study by Consultancy EU published last March found that 12 of Spain’s 14 installed biomethane plants were connected to the national gas grid with output estimated around 0.5 terawatt hours/year (TWh/year). Some producers are already positioning themselves for producing higher volumes as demand is expected to rise over time, particularly as FuelEU Maritime’s compliance target will tighten from 2030. Moeve plans to develop 30 biomethane facilities across Spain by 2030, with a combined expected capacity of around 4 TWh/year, or roughly 260,000 mt/year. F
