Sub-Product

E-methanol is produced by combining green hydrogen produced by electrolysis of water and a source of sustainable of carbon dioxide (captured CO₂, biogenic CO₂, CO₂ from waste treatment, etc.)

• The hydrogen needed for producing e-methanol is produced by electrolysis of water, while biogenic carbon dioxide is captured for example from a fermentation process. Methanol synthesis is a high-pressure process, carried out at temperatures of 320–450°C and pressures 5-10 MPa, typically using Cu/Zn/Al catalysts.
  
  CO₂ + 3 H₂ → CH₃OH + H₂O
   
• Hydrogen can be produced from methanol by direct reformation of methanol. Methanol Stem Reforming (MSR) reaction is conventionally carried out at relatively low temperatures between 240°C and 320°C, using mostly copper-based catalysts.
  
  CH₃OH + H₂O → CO₂ + 3 H₂

E-methanol can be used as a chemical intermediate, a solvent, as a fuel, especially for fuel cells, but also as a hydrogen carrier to safely transport hydrogen over long distances.
