The U.S. Navy has opened the first E85 station at Joint Base Pearl Harbor-Hickam. The 10,000 gallon tank contains 85 percent plant-based ethanol blended with 15 percent gasoline, which can be used in all flex fuel vehicles. Two more Navy E85 stations are planned to open. Marine Corps Base, Hawaii, has the only other E85 station in the state. (U.S. Navy photo by Denise Emsley)
