Are You Storing Your Biodiesel Properly?
Those of us producing our own biodiesel fuel are probably aware of how important it is to store the fuel properly, especially when the weather turns warm. Your storage container is an important part of making biodiesel. It’s essential to choose a storage container that is not only safe, but can increase the life of the fuel.
If biodiesel is stored in a container with little head space then it can be held for longer periods of time. Also the biodiesel containers should be protected from the weather and direct sunlight. Long term storage in damp conditions of a partially filled container can lead to condensation. Keep your fuel tanks as filled as possible even if you have to blend the fuel. This should be done especially in the rainy winter months or when the fuel is not being used. Corrosion of metal fuel tanks can occur due to the condensed moisture that accumulates.
Water condensation also creates a good environment for the growth of bacteria and fungi which feed on the biodiesel hydrocarbons. These organisms accumulate and grow over periods of time and resemble a film or slime. Because biodiesel is such a strong solvent it can cause the slime to separate from the tank walls. This free floating slime can clog fuel filters which in turn will cause the engine to stop suddenly.
There are several products available for sale called biocides that can kill or prevent this growth. The use of biocide will kill any bacteria and fungus that happens to be growing in the fuel tank. The biocides will not interfere with the combustion of the fuel or effect the way the engine operates. You must remember that biocides are very toxic and should only be used as the manufacturer recommends.
By taking the right precautions, you can keep your biodiesel free from algae for much longer. Sunlight and water are your fuels number one enemy; by keeping them away you keep your fuel quality high.
