Understanding the Positive and Negative Properties of Biodiesel

Biodiesel is a renewable, eco-friendly fuel that offers cost and environmental benefits, but it also introduces complexities in storage and handling. To maximize performance and fuel stability, proper quality assurance, storage, and maintenance practices are essential.

The Benefits of Biodiesel Blends

  • Lower Carbon Footprint – Reduces greenhouse gas emissions compared to petroleum diesel.

  • Renewable Fuel Source – Made from soybean oil, animal fats, and recycled cooking oil.

  • Compatible with Diesel Engines – Works as a drop-in fuel for most diesel engines.

  • Potential Cost Savings – Can be cheaper than petroleum diesel, depending on market conditions.

Challenges and Risks of Biodiesel in Storage

Despite its benefits, biodiesel can create stability and fuel quality issues if not properly managed.

  • Variability in Quality – Different feedstocks (e.g., soy, animal fat) and blending methods impact fuel performance.

  • Shorter Shelf Life – Biodiesel oxidizes faster than petroleum diesel, with an untreated shelf life of just 2–6 months.

  • Increased Water Absorption – Biodiesel has a higher affinity for moisture, leading to contamination and microbial growth.

  • Potential Engine Issues – If improperly blended or stored, biodiesel can cause filter plugging and injector deposits.

How to Ensure Biodiesel Fuel Quality

To minimize risks and maximize performance, follow these best practices for biodiesel fuel management:

  • Choose BQ-9000® Certified Suppliers – The National Biodiesel Board operates the BQ-9000 certification program, ensuring strict quality standards.

  • Ask Your Supplier About Blending and Storage Practices – Not all biodiesel blends are created equal, even if they meet ASTM D6751 specifications.

  • Use Stability Additives – If biodiesel is present, apply stabilizers to prevent oxidation and degradation.

  • Conduct Routine Fuel Testing – Test annually for stability, microbial growth, and contamination.

  • Store Biodiesel Properly – Maintain storage tanks at optimal temperatures and prevent water accumulation.

The Bottom Line: Managing Biodiesel for Long-Term Performance

Biodiesel offers major sustainability advantages, but fuel stability and quality assurance are critical for preventing costly storage and engine issues. By following proactive fuel management practices, businesses can enjoy the benefits of biodiesel without sacrificing reliability.
