Most efforts to capture and reuse carbon dioxide produce more carbon dioxide than they capture, and they are not able to reduce enough emissions to meet the Paris Agreement's goals, said researchers from Radboud University, the Netherlands.
The researchers also cautioned that the technologies which seem to be adequate are often not ready in the commercial marketplace.
Carbon dioxide capture and utilization (CCU) works by capturing carbon dioxide emissions from industrial emissions, and then utilize them to produce chemicals, fuels, and other materials. Although the concept appears to be promising, according to New Scientist, Radbud University researchers discovered that 32 out of 40 technologies produced more carbon than they captured. Only four technologies produce very little carbon and are ready to be put into practical use.
