Advantages & Disadvantages of Biodiesel Compared to Petroleum Diesel
Advantages
Disadvantages
  • Made from non-petroleum, renewable resources that can be produced domestically
  • Can be used in most diesel engines, especially newer ones
  • Less carbon monoxide, particulates, and sulfur dioxide emissions
  • 78% less carbon dioxide (CO2) production
  • Biodegradable
  • Non-toxic
  • Safer to handle
  • Slightly lower fuel economy and power (10% lower for B100, 2% for B20)
  • Currently more expensive
  • More nitrogen oxide emissions
  • Transportation & storage of B100 require special management
  • B100 generally not suitable for use in low temperatures
    B100 thickens at temperatures under 40 degrees F.  Additives and blends can be used to reduce these problems.
  • Concerns about B100's impact on engine durability

 

B100 is 100% biodiesel, B20 is a 20% blend of biodiesel with petroleum diesel.
