The Antong 27, a refueling vessel, refuels a container ship with biofuel at Yantian Port on April 14, marking a historic moment as international ships in Shenzhen embrace biofuel for the first time. The container ship received 500 tons of B24 biofuel alongside 500 tons of low-sulfur fuel oil. With global shipping under pressure to cut carbon emissions, biofuels have emerged as a promising alternative that offers environmental sustainability and accessibility benefits. B24 biofuel, comprised of 24% biodiesel, has the potential to reduce emissions by up to 20%, which makes it an attractive option for conscientious ship operators.
