The Navy recently used advanced biofuel to power its Great Green Fleet, a selection of aircraft and surface ships of the U.S. Navy’s Carrier Strike Group, to test the fuel’s performance in an operational setting. The demonstration took place July 17-18 off the coast of Hawaii as part of the Rim of the Pacific Exercise. The Fleet also showcased energy efficiency technology that increase combat capability by allowing ships to achieve greater range and reduction of dependence on a vulnerable logistics supply chain. Additionally, the demonstration included numerous maritime efficiency measures.
