During a round-trip between Mongstad in Norway and Iceland's Reykjavik, the Swedish shipping line's dual-fuel tanker Fure Valö sailed on a 30/70 blend.

The smaller portion of the mix was cooking oil, while the remaining portion - marine gas oil. Equinor's refinery in Mongstad supplied the fuel.

The blend has a certified reduction in greenhouse gas emissions of at least 87.5% vs its fossil fuel equivalent.

"The initial results were positive, as no adverse effects on performance or consumption were detected compared to conventional marine gasoil," Furetank said in a press release.

The companies plan to continue testing Equinor's blend, with another five-to-six round-trips between Norway and Iceland: "[...] prove performance in the harsh weather-exposed trade on the North Atlantic, as well as and handling over time."

Lars Höglund, Furetank's CEO, commented, "Acting as test pilots for this new lower-emission fuel is an important and honorable mission for us. Even if we primarily run our dual-fuel vessels on LNG/LBG [liquefied natural gas/liquid biogas] or gasoil today, they are designed to be flexible, future-proof and easily converted to run on any fuel that will prove to be the right choice for the future."
