Keep an eye on this emerging fuel, since it comes drop-in ready for any diesel vehicle.
Renewable diesel is a diesel fuel made from oils and fats, such as waste greases, tallow, and palm oil. Unlike biodiesel, renewable diesel has the same molecular composition as petroleum diesel. However both fuels are ready for use immediately – no vehicle conversion required. If the fuel is produced using low-carbon feed stock, renewable diesel has the capability of reducing greenhouse gas emissions and tailpipe pollution.
Renewable diesel has yet to become readily available in Washington State. Instead, the fuel is primarily consumed in California, where demand is highest due to the state’s low carbon fuel standard.
