Biodiesel Storage: How to Avoid Bacterial Growth in Your Biodiesel

Biodiesel storage is becoming more vital with the increasing attractiveness of biodiesel, which is made from renewable materials such as Canola and Soybean. Oil that is taken from such sources is changed into biodiesel by a chemical reaction called transesterification. The benefit of using biodiesel lies in the fact that it burns more cleanly and can lubricate better than petro diesel. This diminishes the reliance we have on fossil fuel. However, storing biodiesel has the risk of infecting it with bacteria, and avoiding the outgrowth is essential in having a cleaner fuel.

Cause of Bacterial Growth

If you are going to store biodiesel appropriately, you can keep it for as long as six months and there would be no problem as long as dampness is kept out. When humidity is present, however, bacteria can flourish and multiply.

The Danger of Moisture

Aside from causing microorganisms to grow, moisture can also influence the performance and preservation of equipment. Bacteria and algae growing on your storage tank also generate residues that are acidic and can oxidize your tank bottom.  To prevent bacteria from growing in your biodiesel storage tank, always fill your container to the top and keep it closed. Partially filled storage tanks cause condensation, which promotes the growth of microorganisms. You should also conduct a periodic testing for bacteria on your stored biodiesel.
