The U.S. Department of Energy (DOE) has released a Notice of Intent (NOI) to fund the Bipartisan Infrastructure Law’s $3.5 billion program to capture and store carbon dioxide (CO2) pollution directly from the air. The Regional Direct Air Capture Hubs program will support four large-scale, regional direct air capture hubs that each comprise a network of carbon dioxide removal (CDR) projects to help address the impacts of climate change, creating good-paying jobs and prioritizing community engagement and environmental justice. In addition to efforts to deeply decarbonize the economy through methods like clean power, efficiency, and industrial innovation, the widespread deployment of direct air capture technologies and CO2 transport and storage infrastructure plays a significant role in delivering on President Biden’s goal of achieving an equitable transition to a net-zero economy by 2050.
Direct air capture is a process that separates CO2 from ambient air. The separated CO2 is then permanently stored deep underground or converted for use in long-life products like concrete that prevent its release back into the atmosphere. This differs from carbon capture systems at industrial facilities and power plants that prevent additional emissions from being released into the air in the first place.
By midcentury, CDR will need to be deployed at the gigaton scale. To put this in perspective, one gigaton of subsurface sequestered CO2 is equivalent to the annual emissions from the U.S. light-duty vehicle fleet—the equivalent of approximately 250 million vehicles driven in one year.
Each of the projects selected for the Regional Direct Air Capture Hubs program will demonstrate the delivery and storage or end use of removed atmospheric carbon. The hubs will have the capacity to capture and then permanently store at least one million metric tons of CO2 from the atmosphere annually, either from a single unit or from multiple interconnected units.
In the development and deployment of the four regional direct air capture hubs, DOE will also emphasize environmental justice, community engagement, consent-based siting, equity and workforce development, and domestic supply chains and manufacturing.

To learn more about DAC and other CDR approaches, please also join DOE for the virtual Carbon Negative Shot Summit on July 20 and 21, 2022. The Summit will convene a diverse set of perspectives to discuss the development and deployment of CDR technologies and infrastructure in the United States, as well as explore justice and equity principles and workforce development opportunities.
DOE’s Office of Fossil Energy and Carbon Management (FECM) funds research, development, demonstration, and deployment projects to decarbonize power generation and industrial production to remove carbon dioxide from the atmosphere and to mitigate the environmental impacts of fossil fuel production and use. Priority areas of technology work include point-source carbon capture, carbon dioxide conversion, carbon dioxide removal, reliable carbon storage and transport, hydrogen production with carbon management, methane emissions reduction, and critical minerals production.
