Oldendorff Carriers collaborated with the Massachusetts Institute of Technology (MIT) to study the long-term stability of a B20 advanced biofuel blend used on one of their vessels. The study observed microbial contamination, oxidative degradation, and the impact of various storage conditions over a year. It concluded that biocide addition is recommended to preserve biofuel blends, and antioxidants should be added for long-term onboard storage. No sediment formation was observed, and the impact of storage temperature on degradation remains uncertain. The study’s findings were presented at an AIChE meeting in November 2023, and will assist the maritime community in managing biofuel blends for extended periods.
