PNNL researcher Rich Hallen helped develop a process that converts ethanol to jet fuel in partnership with LanzaTech. Though the ethanol can be sourced from any raw material, sugar, corn, trash etc., LanzaTech produces ethanol using waste gas emissions from industrial sites. By coupling the waste gas to ethanol and ethanol to jet processes, the team can make industrial waste gases into jet fuel. An international standards body, ASTM, just revised their standard to allow ethanol as a feedstock to produce jet fuel.
