“The cost of trapping, storing and compressing CO2 is enormous,” says Ujor. “At present, the economics does not yet add up positively to warrant scale up at the level that we direly need the technology to work.”
Also, the energy sources of BECCS operations are, for the most part, fossil-based, so it could be counterproductive to put more CO2 in the air in an effort to trap and store CO2, he adds. Shifting energy sources away from fossil fuels may be necessary first. Technical barriers also exist, specifically, the safe storage of carbon dioxide. The security of a storage site is crucial because the leak of highly concentrated carbon dioxide would be
for public safety, the ecosystem of the site, and the Earth’s climate. Extensive studies need to be conducted to determine how well and how safely CO2 can be stored without harming the environment, says Ujor.Tech to capture and reuse carbon is on the rise. But can it help the world reach its climate goals?However, BECCS remains controversial because of concerns about the sustainable scalability of the technology.
