Cost plunges for capturing carbon dioxide from the air

Pulling carbon dioxide (CO2) from the air and using it to make synthetic fuel seems like the ultimate solution to climate change: Instead of adding ever more CO2 to the air from fossil fuels, we can simply recycle the same CO2 molecules over and over. But such technology is expensive—about $600 per ton of CO2, by one recent estimate. Now, in a new study, scientists say future chemical plants could drop that cost below $100 per ton—which could make synthetic fuels a reality in places such as California that incentivize low-carbon fuels.
