What is renewable diesel?
Renewable diesel fuels are fuels that are used in diesel engines in place of or blended with petroleum diesel, but are made from renewable resources such as vegetable oils, animal fats, or other types of biomass such as grasses and trees. Biodiesel is an example of a renewable diesel fuel that is available today. Biodiesel is a fuel that performs like a mineral diesel, or derv, but is derived from a renewable energy source. In the UK interest is mainly focussed on producing biodiesel from oilseed rape. The technical term for the resulting fuel is rape-methyl ester (RME). Any vegetable oil, including used frying oil, generally has potential for the production of biodiesel. Crude rape seed oil undergoes the process of esterification, which removes the glycerin allowing the oil to perform like mineral diesel. Biodiesel can be mixed with normal diesel, so vehicles require no modifications to use it. No significant differences in engine performance were recorded when comparisons were made b
