The Rise of Renewable and Low-Carbon Methanol

Introduction
Methanol is one of the chemical industry’s major building-block molecules. It is used to produce formaldehyde, acetic acid, fuels, solvents, and numerous downstream chemicals. Conventional methanol is commonly produced from synthesis gas derived from fossil feedstocks, which creates a significant carbon footprint. Renewable and low-carbon methanol routes aim to reduce lifecycle emissions by changing the source of carbon, hydrogen, and process energy. Interest has also expanded because methanol can serve as a liquid energy carrier and a marine fuel alternative.

Conventional Methanol Production
Traditional methanol production begins by creating synthesis gas containing hydrogen, carbon monoxide, and carbon dioxide. Natural gas reforming and coal gasification are established routes in different regions. The syngas composition is adjusted and compressed before passing over a catalyst...
