WASHINGTON -- The Defense Logistics Agency is buying 450,000 gallons of drop-in biofuel, accelerating demonstration of a homegrown fuel source that can reduce dependence on foreign oil. The biofuel is made from a blend of non-food waste from the Louisiana-based Dynamic Fuels LLC and algae produced by Solazyme. The fuel will be used in the Navy's demonstration of a Green Strike Group in the summer of 2012 during the Rim of the Pacific Exercise. The biofuel will be mixed with aviation gas or marine diesel fuel for use in the demonstration. In preparation for the demonstration, the Navy recently completed testing of all aircraft, including F/A-18 and all six Blue Angels and the V-22 Osprey, and has successfully tested the RCB-X (riverine command boat), training patrol craft, self defense test ship, and conducted full-scale gas turbine engine testing.
