The U.S. Navy is moving forward with plans to create a "Green Strike Force" by purchasing 450,000 gallons of drop-in biofuel to be used on jets and vessels. The contract was signed with Dynamic Fuels, a joint partnership between Tyson Foods and Syntroleum Corp. that creates fuel from repurposed cooking oil. Dynamic Fuels signed a subcontract with Solazyme, which makes algae-based fuels, for 100,000 gallons to fill the order.
