Sustainability and fuel diversity are key trends in the H1 2025 findings. Uptake of FAME-based biofuel blends, notably B30 RF, is increasing across ports including Singapore, Algeciras and Antwerp. This is being driven by regulatory clarity from MEPC 83 and ISO 8217:2024, which confirmed that blends up to 30% are treated as conventional fuels, simplifying NOx compliance. FOBAS testing to date has found no systemic operational issues with these blends, with most quality considerations linked to the conventional fuel components. This approach will be essential as the industry accelerates its transition to low- and zero-carbon fuels.”
