iii Abstract Methanol synthesis has been the subject of many improvements over the last decades since it became more cost effective and scalable than earlier high pressure technology.
The process flow of Route 3 is similar to that of Route 1 . Route 3 uses a coelectrolysis unit and a MeOHsynthesis unit. In the coelectrolysis unit, steam and CO 2 are reduced to syngas by the SOEC after pressurization (up to ~ MPa). The syngas is then sent to the methanolsynthesis unit and converted to MeOH.

Methanol can be produced from any feedstock that contains carbon such as natural gas, coal, biomass, and CO 2. Methanol production from syngas. About 90% of methanol production is currently from natural gas, and other technologies cannot be substituted on an industrial scale according to undesirable efficiency.
Methanol production mainly consists of three pathways: traditional chemistry from syngas, alternatives methanol production other than syngas, and green methanol production from carbon dioxide (CO2) and hydrogen (H 2) ( Giulia and Manenti, 2016 ).
