This requires the right geological conditions.
The CO2 is then compressed to knock out the water and sent by pipeline, or sometimes by ship, to a location where it can be reused or stored.įor long-term storage, “really the only option is to put it deep underground,” Herzog said. The most common way to do that, said Herzog, is to put the flue gas into contact with a liquid solvent, which pulls the CO2 out in a process called chemical scrubbing. It works like this: Instead of sending carbon pollution (or “flue gas”) from burning fossil fuels up a smokestack and into the atmosphere, it is trapped and put through a chemical process. But there are important differences.Ĭarbon capture reduces the amount of carbon pollution that would otherwise go into the atmosphere by catching it at the source of pollution, then storing it or reusing it. “Carbon capture” is often used as catch-all term for what are actually two sets of technologies – carbon capture and carbon removal. Others, however, fear that this is a reckless bet on technology that is expensive, unproven at scale and too far away from full development to provide a meaningful answer to the climate crisis.Īnd they criticize these technologies as a dangerous distraction from policies to cut down fossil fuel use. But it’s “a tool in our portfolio” of options, he told CNN. “There’s no silver bullet here,” said Howard Herzog, Senior Research Engineer in the MIT Energy Initiative, who has studied carbon capture for four decades. Very few people claim that carbon capture and removal alone will solve climate change. In its 2022 report, the United Nations’ Intergovernmental Panel on Climate Change said that “all available studies require at least some kind of carbon dioxide removal to reach net zero” – where the world removes as much planet-heating pollution from the atmosphere as it emits.Įven if emissions fall significantly, the world would still need to remove between around 10 to 20 billion tons of carbon dioxide every year, according to the IPCC.
