O2Diesel Corporation has received an additional $1 million in funding from the Department of Defense for 2007 to continue its existing demonstration projects and develop a cleaner-burning alternative diesel fuel.
O2Diesel has been under contract to develop a new fuel for the Department of Defense that will be composed of at least 20% renewable sources including ethanol and the company’s proprietary biomass-derived stabilizing additive.
Testing of the new fuel is currently underway at the Southwest Research Institute in San Antonio, Texas. The research will be followed by an expanded in-use fleet demonstration at Nellis Air Force Base in Las Vegas where the company’s original O2Diesel fuel—an ethanol-diesel blend of 7.7 vol% ethanol treated with the stabilizing additive. The Nellis Air Quality Demonstration Program will increase the vehicle test fleet in the coming months under the new allocation.
In October, O2Diesel Corporation entered into an agreement with Ben Franklin Transit (BFT) in Richland, Washington, to begin testing a blend of its O2Diesel e-diesel in combination with a B20 biodiesel blend in 20 transit buses. (Earlier post.)
The addition of ethanol to diesel lowers the pour point (the temperature at which the fuel begins to gel). Conventional practice for winter blends has been to mix No. 2 diesel with No. 1 diesel to lower the pour point. The use of e-diesel may reduce the need to blend No. 1 diesel into winter blends (depending upon the ethanol content and other additives).
