Carbon Capture Versus Direct Air Capture [Updated November 16, 2021]   [open pdf - 532KB]

From the Document: "Carbon capture and direct air capture (DAC) have gained prominence in recent years as options to address climate change. The two technologies have similarities (beyond their names), but they also have differences. Key differences include how the technologies work, where the technology can be used, how the technology can address climate change, and levels of federal support. Congress affirmed its support for these technologies in Section 40301 of the Infrastructure Investment and Jobs Act (IIJA; P.L. 117-58): 'carbon capture and storage technologies are necessary for reducing hard-to-abate emissions from the industrial sector, which emits nearly 25 percent of carbon dioxide emissions in the United States ... carbon removal and storage technologies, including direct air capture, must be deployed at large-scale in the coming decades to remove carbon dioxide directly from the atmosphere ... large-scale deployment of carbon capture, removal, utilization, transport, and storage--is critical for achieving mid-century climate goals; and will drive regional economic development, technological innovation, and high-wage employment.' The following analysis explains key differences between the two technologies to inform ongoing congressional deliberations regarding the merits of these technologies, rationale for federal support, and funding level considerations."
