The CCUS Process
CCUS is a proven process that captures, transports and securely stores CO₂ — turning emissions into opportunity by supporting decarbonization and enhancing asset performance.

Capture

CO2 is captured before it enters the atmosphere. It is then purified and compressed into a liquid-like form.

Transport

CO₂ is transported through specialized, highly monitored and regulated steel pipelines to a storage well.

Storage

Storage occurs deep underground, where it is safely isolated far beneath freshwater and deposited into a targeted geologic layer where it fills in the gaps in naturally porous rock and is permanently sealed above by a thick layer of impermeable rock.

Utilization

CO2 can be used to enhance oil and natural gas recovery. When deposited into mature reservoirs, it can help release additional oil and natural gas, significantly improving the production of wells.

Captured carbon can also be used to create essential products such as concrete, fuels and chemicals — turning CO2 emissions into building blocks for new industries.

How a Target Site is Selected

Geologists identify areas where porous rock layers are naturally sealed by thick, impermeable layers known as cap rock.

Once a site is selected, equipment is used to drill the storage well and build the pipeline. Afterwards, the surface is restored to the owner’s expectations. Landowners are compensated for the use of their land, both above and below ground.

CCUS is a Safe Process

A graphic that reads, "Globally, nearly 400 million tons of CO2 have been safely stored using CCUS".
A graphic that reads, "Over 900 large-scale CCUS projects are under development, operating, or under construction."
Safety is foundational. The U.S. has a century of underground storage experience, and each CCUS site undergoes rigorous permitting and oversight by the EPA or authorized state agencies. Permitting, operation, testing and long-term monitoring adhere to strict standards, and wells are continuously monitored twenty-four hours a day, seven days a week, three-hundred-sixty-five days a year.

Fueling Prosperity

CCUS can unleash new economic opportunities across Appalachia, attracting investment from advanced manufacturing, technology and infrastructure projects, while supporting job creation and community benefits. By addressing emissions and enhancing natural gas recovery from existing wells, CCUS is a pathway to long-term regional prosperity and environmental stewardship.

What is Carbon Capture, Utilization & Storage (CCUS)?

CCUS is a process that captures carbon dioxide (CO₂) before it enters the atmosphere, securely transports it through steel pipelines, and either permanently stores it deep underground or puts it to beneficial use in industrial applications. Watch the video above to learn more about CCUS.

How does the CCUS process work?

The process consists of four main steps:

  • Capture: CO₂ is captured from industrial facilities, such as power plants, cement factories and steel mills, before it enters the atmosphere.
  • Transport: The captured CO₂ is compressed and securely transported through regulated steel pipelines.
  • Storage: The CO₂ is embedded deep underground into carefully selected geological formations designed to safely contain it.
  • Utilization: Instead of releasing CO₂ into the atmosphere, it can be put to work in useful ways, such as helping produce more energy from existing wells or making products like concrete and building materials.
Is CCUS safe?

CCUS is a well-established technology that builds on decades of underground storage experience in the United States. Storage sites are carefully selected for their ability to contain CO₂ deep underground, using natural rock formations that help prevent it from reaching the surface. Projects must meet strict permitting, testing, monitoring, and regulatory requirements for well construction, testing and monitoring, with multiple safeguards in place to protect people and the environment.

How is CCUS regulated?

CCUS projects are regulated by the U.S. Environmental Protection Agency (EPA) or authorized federal or state agencies to administer programs. Projects must meet strict requirements for permitting operation, monitoring, and long-term stewardship.

How are storage sites selected?

Potential storage sites undergo extensive geological evaluation to ensure the safe and permanent storage of the CO2. Each site must also meet federal and state regulatory requirements before development.
