Bio-ethanol is well known for its direct application for transportation fuel as well as for various other fuels after conversion. The use of bio-ethanol is currently sought after as a fuel source for renewable energy such as hydrogen production and bio-jet fuel production. Worldwide attention is directed to efficient conversion of bio-ethanol to environment-friendly hydrogen and bio-jet fuel. Conversion of bioethanol to hydrogen and bio-jet fuel is surveyed.
