The maritime industry’s rising demand for reduced emissions bunkering fuel could be met by lower grade products – such as biodiesel that does not meet road fuel standards – according to an Argus Media report of its conference on the sector.

Lower grade biofuels could offer a near-term and cost-effective alternative to traditional fuels, the 16 October report said.

As higher-quality biofuels such as biodiesel with a low cold filter plugging point (CFPP), as well as drop-in fuels including hydrotreated vegetable oil (HVO) and hydrotreated esters and fatty acids for sustainable aviation fuel (HEFA-SPK), were primarily directed at road and aviation markets, this led to higher costs and reduced availability for maritime use, conference delegates told Argus.

Looking ahead, new bio-based fuels such as pyrolysis oil could also play a role in the maritime sector, the report said.
