The G2 Difference

G2 Diesel (G2) is a revolutionary new green fuel made primarily from soybean oil and ethanol. Although similar to standard biodiesel, there are significant differences. Some of these benefits are summarized in the following sections.
Naturally Clean
G2 reduces emissions of greenhouse gases to levels lower than conventional biodiesel.
While conventional biodiesel uses up to 15% methanol in its manufacturing process, the G2 process uses as little as 1% non-renewable feed stock and only environmentally safe ethanol in its processes.
The G2 process produces minimal toxic by-products, no methanol or methanol vapor and no wastewater. The competitors' methods can produce all of these environmentally damaging wastes.
The G2 process uses as much as 70% less energy to produce than traditional biodiesel manufacturing processes.
G2 is as much as 99% agricultural in material and can be likened to a food product. The fuel is not heated or washed with water during the manufacturing process; therefore, eliminating wastewater and wasted energy. The use of ethanol in the manufacturing process also eliminates the risks associated with handling a petroleum product such as methanol.
A Practical Solution
Historically; blended biodiesel, in concentrations greater than B20 (20% biodiesel), has shown a propensity to increase viscosity and reduce flow through fuel filters in cold weather applications.
- G2 has a cloud point of 19F, as much as 30F lower than traditional biodiesel.
- G2 has a gel point of 0F, which is as much as 45F lower than traditional biodiesel products. This allows the use of the product in parts of the Northern U.S. previously excluded from reaping the benefits of biodiesel use. When blended with #2 diesel, customers have reported successful use at temperatures less than -20F.
- G2 combusts more completely than #2 diesel fuel, reducing carbon deposits in engines.
- G2 combusts more efficiently than #2 diesel fuel, resulting in less lost energy in the form of heat, and more useable net energy per gallon. The newly mandated ultra low sulfur diesel decreases the lubricity that diesel engines rely on for supplemental lubrication. G2, in concentrations of as little as 1%, adds lubricity to the fuel; thus, extending engine life.
- G2 may be used in higher concentrations than standard biodiesel, allowing fleet operators to use more biodiesel. This helps to offset, through usage credits, the mandatory replacement of existing vehicles with alternative fuel vehicles as required by the Energy Policy Act of 1992 (EPACT).
Independent field tests have proven, to the satisfaction of Management, that G2 actually cleans and improves operation of aging diesel engines.
