Coconut Oil Jet Fuel Matches Kerosene's Efficiency in Engine Tests

Researchers at Osaka Metropolitan University have developed a low-energy method to produce jet fuel from discarded coconut oil, and their engine tests show it performs nearly as efficiently as conventional kerosene. Blending up to 50% biofuel with kerosene maintained thermal efficiency and thrust, while cutting unburned hydrocarbon emissions by up to 40%. However, the blends burned more fuel and emitted slightly more carbon monoxide, and the fuel's oxygen content currently falls outside aviation standards.
