Safe, secure CO2 sequestration
1PointFive is leveraging the expertise of the teams who have been the leaders in carbon management for more than 50 years. Today we're developing sequestration sites across the U.S. Gulf Coast to securely store CO2 captured via Direct Air Capture and from industrial facilities employing point source capture.
Ample room for excess carbon dioxide
Sequestration hubs are a great solution for addressing residual emissions because they enable secure, scalable, long-lasting CO2 storage. The earth’s geology is estimated to be able to store between 8,000 and 55,000 metric gigatons of CO2. The lowest estimates still far exceed what is projected to be required according to the IEA Sustainable Development Scenario.
-
From the engineering of the Class VI wells that deliver compressed CO2 to the storage reservoirs, to the geophysics surrounding site selection for each hub, the technologies that will be used in 1PointFive’s carbon sequestration have been proven for decades within conventional energy and industrial applications.
-
Our teams have extensive technical, commercial and operational experience. Developing safe and secure storage solutions requires cross-disciplinary skills including geology and geophysics, reservoir engineering, environmental science, chemistry, project management and economics.
-
A variety of forces keep the CO2 securely in place. First, the CO2 is injected beneath an impenetrable caprock more than a mile below the Earth’s surface, and well below the water table. Once inside porous, permeable formations, the CO2 is physically trapped and eventually is dissolved into existing brine or undergoes mineralization, becoming part of the rock around it.
-
Wells surrounding the CO2 injection well help monitor the reservoir 24/7 to ensure safety, security and integrity. All sequestration wells will be permitted by the U.S. Environmental Protection Agency (EPA) or the appropriate state agency, and the entire operation will employ EPA-approved methodologies for Monitoring, Reporting and Verification (MRV).
What is a
Sequestration Hub?
Carbon sequestration hubs bring together everything our partners need for the safe, convenient storage of CO2. We’re not just developing storage facilities—we’re helping create a carbon storage infrastructure that will help take our country and economy to a low-carbon future.

Capture & Transportation
First, CO2 is acquired via Direct Air Capture or point-source capture at an industrial facility. The high concentration CO2 is then compressed and transported across a pipeline network to a sequestration hub.
Compression
At the sequestration site, the CO2 is further compressed to increase the density of the CO2 so it can maximize available storage space by fitting into tiny pores in the reservoir rock.
Injection
An injection well pumps the compressed CO2 more than a mile below the surface of the earth, below an impenetrable caprock.
Trapping
The CO2 is trapped within the reservoir either mechanically, chemically or by binding with minerals that are already present.
Monitoring
A number of wells surrounding the storage reservoir continuously monitor the secured CO2 and provide data for each facility’s MRV program. -
Wells used for geologic sequestration must meet the U.S. Environmental Protection Agency’s Class VI well requirements (or, if applicable, state regulations that are at least as stringent as the EPA’s Class VI well requirements), which are designed to protect public health and underground sources of drinking water.

No. Underground CO2 storage has been in use for decades in energy and industrial applications. In fact, 1PointFive’s parent company has more than 50 years of experience storing CO2 underground. 1PointFive plans to leverage that experience and expertise to develop our sequestration sites.
