Electrically activating chemicals could help remove carbon dioxide from the air, CU Boulder researchers find

Humans send millions of tons of carbon dioxide (CO2) into the air each year—by generating electricity, manufacturing products, driving, flying and doing other routine activities. And while plants can absorb some of that CO2, much of it remains suspended in the atmosphere, where it acts as an insulating blanket that traps heat on Earth.

Scientists believe removing some of that CO2—and either putting it in long-term storage or converting it into something useful—is a potential option for slowing the progression of human-caused climate change. But carbon sequestration, as the process is known, is easier said than done.
