German logistics company DB Schenker and Swiss travel retailer Avolta have agreed a deal to run container vessels with used cooking oil methyl ester (Ucome) for all of Avolta's shipments on the Barcelona-Miami route.
Along with waste-based Ucome, the companies will use "additional units of sustainable marine biofuel, to achieve additional compensation of the biofuel's upstream emissions", according to Avolta.
The biofuels will be used in a book-and-claim framework. Book-and-claim allows detailed accounting for the purchase and transfer of renewable fuels by parties that may not ultimately receive the molecules they acquired.
The companies expect a reduction of up to 150t in CO2 equivalent well-to-wake emissions, or up to 84pc, compared with Avolta's 2023 container volumes on the Barcelona-Miami route.
Biofuel blends remain significantly more expensive than conventional marine fuels, discouraging some from switching. According to Argus price assessments, a blend of 24pc Ucome with very low sulphur fuel oil (VLSFO) dob Algeciras-Gibraltar was at a $174.78/t premium to unblended VLSFO on 18 July, when accounting for Emissions Trading System (ETS) costs.
