NAU Researcher Dr. Eric Morgan has been working with private industry and military partners to develop a mobile synthetic fuels manufacturing unit that makes methanol from hydrogen and CO2. The manufacturing unit is located inside of a trailer for easy mobility. Liquid fuel synthesis using renewable energy and
carbon dioxide has potential climate change mitigation, energy management, and
military mobility/reliability impacts.
Methanol (CH3OH) is the simplest alcohol, consisting of one carbon, one oxygen and
four hydrogen atoms. At room temperature it is a colorless liquid that is less
dense than water, making it a good solvent and fuel. In fact, methanol is used
in some race cars as a high-octane, premium fuel. It is also a drop-in
replacement for ethanol in gasoline, or gasoline itself. NAU has developed a
methanol synthesis reactor that directly converts carbon dioxide (CO2)
and hydrogen (H2) into methanol and water. The reactor operates entirely
on electricity and includes a high-pressure electrolyzer to obtain gaseous
hydrogen directly from purified water. The entire methanol reactor assembly was
installed in a mobile trailer so that methanol can be made where “free” streams
of carbon dioxide exist: breweries, power plants, and wastewater facilities.
The trailer includes a distillation unit that separates the methanol and water
mixture on site so that the synthesized water can be reused in the
electrolyzer. The pure methanol can then be used as a fuel, or stored and sold
