Scientists in the UAE have successfully run tests on jojoba methyl ester in a standard diesel engine. Created by mixing jojoba oil with a small amount of methanol, the fuel performed as well as diesel, and ran cleaner and quieter than its diesel counterpart.
Jojoba oil is extracted from the nut of a desert shrub, and as such is considered to be a renewable resource. It contains less carbon and no sulfur, cutting carbon monoxide, carbon dioxide and sulfuric acid emissions to much lower levels.
