Direct air capture of CO2 is becoming a business, for better or worse

Direct air capture of CO2 is becoming a business, for better or worse

The conference was the strongest sign yet that direct air capture is becoming a business–for better or worse . For better? Because air capture technology has enormous potential to reduce CO2 concentrations in the atmosphere, albeit very slowly and at considerable expense. The costs remain unknown, with estimates ranging wildly from $30 per ton of CO2 captured, which is almost surely too low, to more than $600 a ton, which is almost surely too high, although the bigger number comes from a report [PDF, download] from the respected American Physical Society. For worse? Because as air capture transitions from academia into the marketplace, the start-up companies will need to generate revenues to stay alive, even if those revenues enable more oil to be pumped out of the ground.
