Why CO2 capture and storage will fail in the fight against climate change

Current international scenarios for limiting global warming to less than 1.5 degrees by the end of the century also rely on technologies that remove CO2 from the Earth's atmosphere faster than humans release it. That means removing CO2 at a rate of 1-30 gigatons per year by 2050. But the hypotheses about how quickly these technologies – largely experimental and very expensive – appear to have no solid foundation. A new study, "Feasibility of Achieving Gigaton CO2 Storage by Mid-Century", published in Nature Communications  Yuting Zhang, Christopher Jackson and Samuel Krevor of the Department of Earth Science and Engineering at Imperial College London now demonstrate that existing projections are unlikely to be feasible at current growth rates.” (Greenreport editorial team, more at greenreport.it)
