Industrielle CO2-Nutzungen: Ein Überblick

Industrial CO2 use - An overview: Technologies for CO2 utilisation have recently been gaining in importance. Some CO2 uses, such as the production of urea and methanol, are practised on an industrial scale. Many others are being tested. Good progress has been made in the production of plastics and synthetic fuels. The use of carbonised CO2, e.g. for the production of building materials, can lead to the longterm storage of CO2. Synthetic fuels, however, only store the used CO2 for a short time, but prevent the use of fuels made from petroleum. Re-sequestration keeps the CO2 in the cycle. Synthetic methane can play an important role for energy storage and ammonia for the transport of green hydrogen. Overall, however, the contribution of CO2 uses to climate protection is rather limited. To limit global warming, a combination of many climate engineering methods is required in addition to a drastic reduction of global emissions.
