AIRCO’s synthetic diesel has met ASTM D975, the industry standard specification for diesel fuel. In simple terms, ASTM D975 is the same quality standard that diesel sold at U.S. fuel pumps must meet. It specifies required properties of the fuel that control performance aspects such as how cleanly the fuel burns, how easily it ignites, and how it flows in cold weather. So what is synthetic diesel? It is diesel-range fuel made from chemically produced molecules rather than refined from crude oil. AIRCO makes it from carbon dioxide (CO₂), water, and power, using its AIRMADE™ process. The first batch from AIRCO’s new manufacturing hub in New Britain, Pennsylvania, was tested by a certified fuel testing laboratory. The lab confirmed that a one-gallon sample met all ASTM D975 performance criteria for grade 1-D S15 diesel fuel. Put simply, AIRCO Diesel meets the same quality bar as the diesel operators already put in their trucks, tractors, and generators. It is designed for existing diesel engines, tanks, and distribution equipment. To celebrate, the AIRCO team filled up a Humvee with AIRCO Diesel and took it out for a test drive. This builds on earlier land and sea demonstrations with U.S. defense partners, including a 2024 Project SynCE demonstration with DIU and the U.S. Army at West Point and a 2023 SOCOM Technical Experiment at Joint Expeditionary Base Little Creek.
