There has been growing support for removing carbon from the atmosphere as a mission critical component of the emissions reduction toolkit. Widescale application of these technologies could decrease GHG concentrations by disconnecting future energy use from GHG emissions, removing prior accumulations of GHGs, and combining with the use of bioenergy to deliver “negative emissions.” These options face challenges as their scale and potential have yet to be realized. Over the last year, the pace of investments in CCUS and Direct Air Capture has accelerated rapidly. What has changed in the last 12 to 18 months for the renewed optimism and interest in CCS and Direct Air Capture? Is there a real market for carbon removal? How big could it be? What emerging business models are commercially attractive? Are there lessons from rapid scaleups, such as the development of COVID-19 vaccines, that could be models for scaling up carbon removal? How scalable are carbon-use technologies such as conversion to cement? What policy mechanisms could accelerate deployment of CCUS?
