Seed: Energy

With the passage of federal legislation in 2007, production of biofuels, such as biodiesel and ethanol, in the United
States has increased in an effort to further energy independence and combat carbon dioxide emissions. Much
like soybeans, the oil within hemp seeds can be extracted and converted into biodiesel through a process called
transesterification. Because hemp can be cultivated on less fertile land with less human intervention, it is thought
that hemp-based biodiesel may offset the demand for soybean-based biodiesel.

Any biodiesel and biodiesel blend must meet stringent regulations to ensure that it functions safely and efficiently
as a fuel, such as those laid out in ASTM D6751 for B100, or 100% biodiesel, and D7467 for B6-B20, or 6-20%,
biodiesel blended with conventional petrodiesel.

Various properties of the biodiesel, including glyceride content, metals content, and assessment for residual methanol
used during fuel production, must be met. These factors relate to the combustion and lubricating properties of
the biodiesel as well as the stability of the fuel itself once produced. Such regulation guarantees that biodiesel and
biodiesel blends are safe and effective to use in properly equipped vehicles.
