Abstract
A Process for making methanol having a deuterium content below 90 ppm, based on the total hydrogen content, comprising the steps: (a) providing hydrogen with a deuterium content below 90 ppm, based on the total hydrogen content, by water electrolysis using electrical power that is generated at least in part from non-fossil, renewable resources; (b) providing carbon dioxide; (c) reacting hydrogen and carbon dioxide in the presence of a catalyst to form methanol.
