Biofuel blends combine conventional marine fuel (typically VLSFO) with biocomponent (generally FAME or UCOME). The numeric label indicates biocomponent percentage: B24 is 24% biofuel, B30 is 30%, B100 is pure biofuel. Biofuel blends are the most established alternative-fuel pathway for existing vessels, requiring no engine modifications within moderate blend ratios.
Voluntary decarbonisation commitments, FuelEU Maritime compliance, charter-mandated reductions
Pure biofuel (B100) has storage stability and compatibility issues for many marine engines. Blends up to B30 are generally accepted by engine OEMs without modification. Singapore and Rotterdam offer B24 as commercial standard; B30 requires specific nomination.
Biofuel sustainability depends on feedstock. Waste-derived biofuels (used cooking oil methyl ester, UCOME) score better on lifecycle carbon than virgin oilseed-based feedstocks. ISCC-EU certification is the common standard for marine biofuel; FuelEU Maritime requires specific certification categories.
Biofuel blends are more expensive per tonne than straight VLSFO. The premium varies by feedstock and certification; premiums of 30-80% over conventional VLSFO are common. FuelEU Maritime and EU ETS costs partially offset this through compliance value.
Biofuel blends can have different cold-flow, water pickup, and microbiological characteristics. Tank hygiene becomes more important. Long-term storage should be limited; consumption within a few months of bunkering is advisable.
