Repsol

A Repsol marine fuel station serving the Barcelona waterfront, where you can top up before heading out to sea. What sets Repsol apart is their serious push into renewable marine fuels — they've signed a major deal to supply green methanol to cruise lines operating out of Spanish ports, with production launching from their Tarragona facility in 2029. It's one of those spots where the everyday business of fueling up quietly connects to a bigger shift happening in how the industry runs.
