Oil Stains on Direct Air Capture?
Affordable direct air capture could shape long-term climate mitigation options. Point source emissions may be the first to be addressed, but the climate change problem is not resolved until the carbon dioxide from the transportation sector is also dealt with. Conflating air capture with a carbon dioxide consuming application like the environmentally questionable EOR should…
