In Norway, classification society DNV has published a white paper highlighting that marine shipping accounted for just 0.6% of global liquid biofuel consumption in 2023, despite rapid growth in bio-blended bunker fuel sales at ports like Singapore and Rotterdam.
The report tracks developments in supply, regulations, and technical considerations, and includes feedback from 12 shipping companies and eight biofuel suppliers. It outlines that 111 million tonnes of oil equivalent of liquid biofuels were produced globally last year—primarily ethanol, FAME, and HVO—with the vast majority, 98.9%, used in road transport. Aviation took 0.5%.
Biofuel blends ranging from B20 to B30 have gained traction in shipping, with Singapore’s sales reaching 518,000 tonnes of B24 in 2023. Rotterdam also reports rising demand for B30 blends. However, supply-side constraints remain, including limited sustainable feedstocks, logistical hurdles, and regulatory fragmentation.
Looking ahead, the paper notes that upcoming IMO mid-term GHG measures, entering into force in 2027, will include both a GHG fuel standard and an economic measure. These, combined with the EU’s FuelEU Maritime regulation that began in 2025, are expected to drive further uptake. The IMO is likely to recognize biofuels under these rules, provided they meet certification and deliver at least a 65% well-to-wake GHG reduction.
