New ISO marine fuel class allows up to 7% biodiesel

In Switzerland, the International Standards Organization has created the new F class of marine fuels that allows for blending of up to 7% of FAME biodiesel, allowing for more 10 ppm sulfur automotive fossil diesel to be used in the marine fuel pool. Adding Cloud Point and CFPP (Cold Filter Plugging Point) to the specifications are meant to help increase the uptake of biodiesel in marine fuels by letting operators know when fuels need to be heated.
