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.
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. Additional information, such as costs and other challenges, is provided in other CRS resources, listed below.
