Methanol plays an important role in the energy and chemistry sectors, since it can be directly used as fuel and energy carrier or involved as precursor in the production of chemicals like dimethyl ether (DME) or olefins (e.g., ethylene and propylene). Methanol demand shows an increasing trend which is fulfilled by involving large scale production facilities. Nowadays methanol is mainly produced from the catalytic conversion of a syngas (i.e., a mixture of hydrogen, carbon monoxide and carbon dioxide) obtained via methane reforming or coal gasification. As an alternative, green/renewable methanol can be produced when hydrogen is obtained via water electrochemical splitting (electrolysis) by exploiting surpluses from intermittent renewable electricity.
