A majority of carbon capture and utilisation technologies, which aim to pull carbon dioxide from the air and use it for emissions-lowering processes, emit more carbon than they remove

“If you’re stuck with such a technology that does not have the potential to really reduce emissions drastically, and preferably to net zero, then that could be a situation that’s undesirable,” says de Kleijne.Stuart HaszeldineMany of the technologies also don’t appear ready for deployment on a large scale, so they may not be helpful in hitting the Paris Agreement’s emission targets by 2030, says de Kleijne.
While the analysis used assumptions about future electricity mix that could change – for example, electricity was assumed to be completely renewable by 2050 – more pessimistic assumptions could actually make CCU even more carbon intensive. De Kleijn hopes the research will eventually be used to help policy-makers and investors decide which technologies are worth investing in.at Global CCS Institute, an international think tank that promotes the use of carbon capture technologies. “CCU appeals to policy-makers and the public because it’s seen as a circular economy. There are some very positive perceptions of CCU, but the point that [the researchers] are making is that not all CCU technologies are the same.
Ultimately, it could make more sense to concentrate efforts on trying to store carbon for thousands of years, says Haszeldine. “It will probably be better, in terms of taking CO2 out of the climate, to just focus on very secure, straightforward capture, transport and storage.”
