Wouldn't it be an elegant solution to use the substance that is most damaging to the climate and threatens the future as a raw material for economic goods and everyday items? In fact, carbon dioxide (CO2), an unavoidable byproduct of civilization, is already being used in the laboratory to produce lower olefins, alcohols and fuels in combination with hydrogen and other chemical reactants, all of which can be obtained sustainably. For such processes to become industrial practice, they must be able to run under 'fluctuating' conditions.

"Fluctuating" means that these processes must also function with fluctuating supplies of energy and starting materials. This is new for chemistry, but cannot be avoided if the energy, for example for the production of hydrogen by electrolysis, is to come from In the grand scheme of things, the goal is to replace petroleum as a raw material base and at the same time to ennoble a problematic waste gas, carbon dioxide, into a raw material. But COTo obtain commercially useful compounds, especially basic materials for the chemical synthesis of valuable products, the extremely stable carbon-oxygen bonds in COmust be activated. This is done catalytically by hydrogenation, i.e.
