Newark, DelawareA new device pulled CO2 from air at $566 a ton in pilot tests.
Heat, the main cost of removing CO2 today, is the barrier the device sidesteps entirely.
Nickel hydroxide electrodes swing a voltage to grab CO2 as carbonate, at 0.8 megawatt-hours per ton versus 1.5-3 for existing plants.
The team projects a sixfold cost drop to $92 a ton at industrial scale.
Researchers linked to startup RepAir Carbon must still prove the projection outside the lab, at far larger scale.
