The study, ‘Utilizing CO2 as a strategy to scale up direct air capture may face fewer short-term barriers than directly storing CO2,’ led by Nicoletta Brazzola of ETH Zurich and published in Environmental Research Letters, examines two potential pathways for implementing Direct Air Capture (DAC) technology. It compares integrating DAC with CO2 storage (Direct pathway) and CO2 utilization (Spillover pathway), using the Multi-level Perspective on Technological Transition to assess both pathways’ technical and non-technical factors, identifying potential short-term barriers and advantages. The authors conclude that neither pathway is clearly superior, suggesting that a dynamic policy approach could be beneficial.
