  Solar Methanol
 
Making methanol from solar energy is an attractive means to store solar energy as a liquid fuel. Methanol may be used as a fuel in internal combustion engines or in fuel cells. The substitution of fossil fuels with solar-derived methanol will result in a significant reduction of emissions.
Our technology uses industrial waste CO2 in the production of methanol. This CO2 can be obtained from concentrated sources like flue gases of fossil-powered plants and cement factories. Large amounts of CO2 are expected to be available as industry responds to regulation to curb CO2 emission.

The recycling of CO2 to methanol could also provides an alternative to CO2 sequestration, especially in areas where geologic sequestration is not an ideal solution. 

   
  Methanol Production
   
  Industrial methanol (CH3OH) is currently produced from synthesis gas (H2+ CO), which is typically derived from fossil fuel (methane). Our technology produces syngas by the co-electrolysis of H2O/CO2 streams using a solid oxide electrolyzer. Unlike the current industrial method which produces significant carbon dioxide greenhouse gas, our approach produces not such emissions.  The co-electrolysis process: CO2+ H2 H2+ CO + 3/2 O2.
   
 
   
  Solar Methanol is produces by reacting the syngas at 510 MPa and 250 C over a catalyst consisting of a mixture of copper, zinc oxide, and alumina: CO + 2 H2 CH3OH.
   
 

The energy required for the co-electrolysis of CO2+ H2O is produced from clean solar thermal energy. Parabolic-trough power technology is the most established of concentrating solar power technologies. The solar power plants use a field of Parabolic-trough collectors to supply thermal energy to a conventional power plant that generates electricity, which drives the high-temperature co-electrolysis process.
