Spanish energy company Repsol on Thursday (18 June) said it has started the commercial supply of co-processed marine fuels with renewable content in the port of Algeciras, one of the main bunkering hubs in the Mediterranean. The company said this marked the deployment of immediate solutions produced by integrating renewable content directly into conventional refinery processes, supporting the decarbonisation of maritime transport. Last week, Repsol launched the first commercial voyage of its new generation bunkering vessel Bahía Candela . During this first voyage, the vessel loaded co-processed fuel at Repsol’s Petronor refinery in Bilbao, reinforcing the company’s end-to-end supply capability by integrating refining, logistics, and delivery. Repsol reportedly chartered the bunkering vessel from shipowner Mureloil. Designed specifically for marine fuel supply, Bahía Candela features multiproduct capabilities and is prepared to operate with low-emission energy solutions. Its diesel-electric propulsion system and advanced energy storage enable optimised efficiency and reduced emissions during operations. “This milestone marked Repsol’s entry into the supply of low-carbon marine fuels in Algeciras, leveraging its integrated value chain and expanding its multi-energy offering in the maritime sector, combining conventional products with low-carbon alternatives, thus, strengthening its ability to adapt to the diverse needs of its customers,” Repsol said in a statement. Co-processing enables the integration of renewable feedstocks, such as oils and residues, alongside conventional streams within refining processes. This generates fuels with a low-carbon footprint and supports a gradual transition towards solutions that will help to decarbonise the sector, providing a cost-efficient and scalable pathway to supply low-carbon fuels that are fully compatible with existing engines and infrastructure, without requiring changes to vessels or port assets, and using current i
