Hemp can provide fuel via 3 processes.
1. Hemp biodiesel – made from the oil of the (pressed) hemp seed.
2. Hemp ethanol/methanol – made from the fermented stalk.
3. Gas, jet, and diesel fuel – by using gasification or pyrolysis.
To clarify further, ethanol is made from such things as grains, sugars, starches, waste paper and forest products, and methanol is made from woody/pulp matter. Using processes such as gasification, acid hydrolysis and enzymes, hemp can be used to make both ethanol and methanol.
In this day of oil wars, peak oil (and the accompanying soaring prices), climate change and oil spills, it’s more important than ever to promote sustainable alternatives such as hemp ethanol. Hemp turns out to be the most cost-efficient and valuable of all the fuel crops we could grow on a scale that could fuel the world.
And as it turns out, the whole reason for hemp prohibition – and alcohol prohibition – may have been a fuel the realisation that oil production is threatened by any competing fuel source, especially one that requires no modifications to your car!
Hemp biodiesel is the name for a variety of ester based oxygenated fuels made from hemp oil. The concept of using vegetable oil as an engine fuel dates back to 1895, when Dr. Rudolf Diesel developed the first diesel engine to run on vegetable oil. Diesel demonstrated his engine at the World Exhibition in Paris in 1900 using peanut oil as fuel. Hemp biodiesel comes from the pressing of the hemp seeds to extract the oil.
Hemp biodiesel can be made from domestically produced, renewable oilseed crops such as hemp. With over 30 million successful U.S. road miles hemp biodiesel could be the answer to our cry for renewable fuel sources. Learning more about renewable fuels does not mean we should not cut back on consumption but does help address the environmental affects of our choices. There is more to hemp as a renewable fuel source than you know
