They depend on nearly free electricity if they want to make fuel.

It could still be useful even if it costs money or net power to grab a significant amount of CO2 out of the air. But the question remains whether it will be better than traditional techniques if they also have similar "free" inputs.

INTEGRATION WITH CARBON-FREE ENERGY
In CE’s lowest-technical risk ‘baseline’ design, all the input energy required onsite is supplied by natural gas. The carbon dioxide from gas combustion is also captured along with the CO2 extracted from the atmosphere, so that no new CO2 is emitted to the atmosphere by our technology.
In the longer term, we expect that carbon-free power will drive air capture. CE is building collaborations to conduct full-scale studies on using solar thermal or nuclear energy as the source of energy for its air capture system.
