Repsol starts commercial supply of renewable marine fuel in Algeciras
Repsol began co-processed renewable marine fuel deliveries in Algeciras, linking the launch to Bahía Candela’s first commercial voyage from Bilbao.
Repsol on June 18 started commercial supply of co-processed marine fuel with renewable content at Algeciras, tying the launch to the first commercial voyage of the bunkering vessel Bahía Candela. The vessel loaded the product at Repsol’s Petronor refinery in Bilbao before delivering supply into one of the Mediterranean’s busiest bunkering hubs.
The Port of Algeciras Bay Authority says the Strait of Gibraltar sees more than 100,000 ships a year, and that bunkering is the port’s leading ship-refuelling activity. Ship supply operations there total about 3 million tonnes a year, giving Repsol a high-volume market for marine fuel deliveries at the exact point where Atlantic and Mediterranean traffic converges.
The port’s recent LNG numbers underline that scale. Algeciras reported 333,833 cubic metres of LNG bunkered in 2025, including 78 ship-to-ship operations, a signal that bunker customers are already using the bay for alternative marine fuel logistics. Repsol’s co-processed offering adds renewable content into that same commercial flow.
Bahía Candela is chartered by Mureloil to Repsol and is described in industry reporting as a hybrid chemical/product tanker with diesel-electric propulsion and a 4.2 MWh battery system. The vessel was built for biofuel and methanol logistics, making it a fit for the kind of marine supply chain Repsol is building around lower-carbon fuels in Spanish ports.
Algeciras is only one piece of that plan. Repsol said its second plant dedicated exclusively to 100% renewable fuels in Puertollano has annual capacity of 200,000 tons and could prevent about 700,000 tons of CO2 emissions a year across the fuel’s life cycle. The company also signed an eight-year renewable marine-fuels agreement with Norwegian Cruise Line Holdings at Barcelona in October 2025, with deliveries due to begin in the 2026 European cruise season.
Taken together, the Algeciras launch places renewable-content marine fuel into a port that already handles millions of tonnes of bunkering traffic each year, while giving Repsol a second Spanish outlet as it pushes renewable fuels through refinery output, chartered tonnage and port-based supply contracts.
