Claim 1 of 4Not checkedA new study from a team led by James Buchen of the University of Delaware demonstrates a battery-based electrochemical carbon-capture technique.View evidenceHide evidence
Not checked
The source study was found, but this claim couldn't be checked against it.
Claim 2 of 4Not checkedThe authors say their method is more viable than previous attempts and has the potential to require less energy, and therefore be cheaper, than conventional reversible-filter carbon-capture systems.View evidenceHide evidence
Not checked
The source study was found, but this claim couldn't be checked against it.
Claim 3 of 4Not checkedThe device works by generating hydroxide at the cathode, which reacts with CO2 to form carbonate or bicarbonate that crosses the separator to the anode, where lower pH converts it back into CO2 gas.View evidenceHide evidence
Not checked
The source study was found, but this claim couldn't be checked against it.
Claim 4 of 4Not checkedIn the device described, both the cathode and anode are nickel hydroxide, and the system is operated by reversing the applied voltage so the same chemistry runs in reverse.View evidenceHide evidence
