Our conclusion: CCS and CCU are important tools in the fight against the climate crisis and represent opportunities that should be seized. Currently, 150 million tonnes of CO2 are removed from the atmosphere every year. In 2050, it will have to be many times that amount if – as is to be expected – fossil fuels are to continue to be used and at the same time CO2 pollution of the atmosphere is not to increase any further. Many questions are still open, for example transport and final storage of these huge quantities. Not surprisingly, technology is currently used primarily in oil and gas production – because it serves to increase yields and is immediately profitable. In general, financing CCS or CCU is the biggest current challenge, especially in developing and emerging countries
