CCU-based Resource Supply for the Chemical Industry (PNG)
It is a plausible scenario to assign methanol (CH₃OH) a central role in supplying the chemical industry of the future. Already today, methanol plays an important role in the chemical industry, being one of the most established commodities.
CCU-based process route for production of methanol includes production of hydrogen via electrolysis, CO₂ capture from the atmosphere or from industrial point sources, and the hydrogenation reaction. Electricity demand for these processes is represented by red arrows. Above the arrow, the specific energy demand is stated, below, the contribution of the process to the total electricity demand of 1 t of methanol is stated. Purification and compression of hydrogen are neglected. For CO₂ hydrogenation, a complete reaction is assumed.
