Fossil resources such as oil, gas, and coal are depleting, which implies that alternative technologies have to be developed to satisfy the demand of Nordic societies for fuels as well as for the thousands of products made out of oil, such as plastics, pharmaceuticals, and paints. In analogy to photosynthetic processes in nature, CO2 can be employed as an alternative carbon source in chemical, pharmaceutical, and energy-related industries to synthesize essential substances. CO2 is a sustainable and cheap raw material, but the development of chemical processes for efficient and selective conversion of CO2 to desired products is a major challenge.
