Michigan-based Warner Petroleum is making strides toward promoting biodiesel as a sustainable maritime shipping fuel. The company supplies fuel to various vessels operating on the Great Lakes, and it sees the adoption of biodiesel as an opportunity to meet environmental standards and reduce emissions from shipping activities. Warner Petroleum started offering B10 and B20 biodiesel blends to Lake Michigan customers in 2022 and expanded to offer B20 to maritime customers in the Detroit and Dearborn areas in 2023. The company expects about 25% of its fuel sales during the current shipping season to include biodiesel blends.
