Biodiesel in North Carolina

Quick Facts about Biodiesel


What biodiesel is

  • Biodiesel is a naturally oxygenated fuel produced from organic feed sources
  • Sample feed stocks include soybeans, cooking oil, animal fats, and used cooking greases
  • Biodiesel can be used in its pure form, B100, and must meet ASTM D6751 specification or dealers can get BQ-9000 accreditation
  • Often blended with petroleum diesel to achieve cost efficiency and improve cold weather performance. A typical blend, B20 has 20% biodiesel and 80% petroleum diesel

Using biodiesel
  • Can be used in any diesel vehicle (bus, truck, farm equipment) without modification
  • Acts as a solvent and can loosen deposits in the fuel system left by petroleum diesel, so it may be necessary to change out your fuel filter after initial use of a high biodiesel blend
  • Vehicles produced prior to 1993 should have rubber seals in fuel pumps and fuel systems replaced with non-rubber (Viton) seals
  • It may also be utilized in stationary applications such as diesel generators and boilers

Performance

  • Biodiesel performs similarly to traditional diesel
  • B100 may result in a minimal power loss at the high end and a slight loss in fuel economy
  • B20 users generally experience no difference in fuel economy from petroleum diesel
  • Reduces wear and tear on the engine, reducing maintenance costs and extending engine life
  • Biodiesel blends can be easily stored and dispensed in existing facilities
  • B100 can thicken in cold weather (below 40 degrees F) and minor adjustments or modifications are required

Emission benefits

  • Significantly lower emissions than petroleum diesel
  • Reduces carbon monoxide by 12% with B20 and 47% with B100
  • Reduces hydrocarbons by 20% with B20 and 67% with B100
  • Reduces particulate matter by 12% with B20 and 48% with B100
  • Reduces air toxins by 20% with B20 and 60-90% with B100
  • Eliminates all sulfur emissions with B100, and a 20% reduction with B20
  • Reduces visible smoke and other noxious odors
  • Possible 78% reduction in carbon dioxide emissions over entire production process

Additional benefits

  • 3.2 units of energy gained for every 1 unit of fossil fuel energy used in producing biodiesel
  • Non-toxic and biodegradable, with no threat to water and soil resources if B100 is spilled
  • Producing biodiesel from oil or animal fat wastes can reduce those materials in landfills
  • Relatively safe with no combustible vapors and a flash point around 300F (B100)
  • Reduces dependence on fossil fuels and provides alternative markets for farmers
  • Low blends of biodiesel (B2) are highly effective at enhancing the lubricity of diesel fuel, a concern when considering new Ultra Low Sulfur Diesel requirements
