Introduction: Why Carbon Capture Technology Is Gaining Attention in America

The United States is investing in new ways to manage carbon dioxide emissions from industrial facilities, energy production, and other economic activities. Among the technologies attracting attention is carbon capture, which involves separating carbon dioxide from an industrial gas stream or directly removing it from the atmosphere.

Carbon capture is becoming an important subject in discussions about industrial modernization, energy infrastructure, and climate technology. American companies and research institutions are developing new materials, separation systems, transportation networks, and underground storage methods intended to make carbon management more practical.

Industries such as cement manufacturing, steel production, chemical processing, and refining can be difficult to decarbonize because some emissions result from the chemical reactions involved in manufacturing, not simply from burning fuel. Carbon capture may help address a portion of these emissions when other reduction methods are insufficient or difficult to implement.

Direct air capture offers a different approach. Instead of collecting carbon dioxide at a factory or power plant, it uses specialized systems to remove carbon dioxide from ambient air. This can potentially address emissions that are already in the atmosphere, although the process currently faces significant energy and cost challenges.

In August 2026, the U.S. Government Accountability Office published a report examining the federal carbon capture tax credit known as Section 45Q. The report highlighted challenges in administering the incentive and evaluating its overall effectiveness. This illustrates that carbon capture development involves not only engineering but also financing, oversight, environmental measurement, and public policy.

What Is Carbon Capture Technology?

Carbon capture technology refers to systems that separate carbon dioxide from a gas stream or remove it from the atmosphere. Once captured, the carbon dioxide may be compressed, transported, stored underground, or used in certain industrial products.

The broader term carbon management includes several connected activities:

• Carbon capture at industrial facilities and power plants
• Direct air capture from the atmosphere
• Carbon dioxide transportation
• Geological storage
• Conversion of captured carbon into selected products
• Monitoring and verification of stored carbon

The U.S. Department of Energy describes carbon management as a collection of technologies that can support emissions reduction and the management of carbon dioxide. It also emphasizes that these technologies should complement other approaches, including energy efficiency, renewable energy, nuclear power, and other lower-emission industrial solutions.

Carbon capture does not automatically make an entire facility emissions-free. The energy required to operate capture equipment, the source of that energy, transportation, and the final destination of the carbon dioxide all influence the overall environmental outcome.

For this reason, credible carbon capture projects need to measure the full system rather than focusing only on the quantity of carbon dioxide collected at one stage.

How Does Carbon Capture Work?

The exact process depends on where the carbon dioxide originates and the technology being used.

1. Identifying the Carbon Source

Engineers first determine the source of the emissions and examine the composition, temperature, pressure, and volume of the gas stream.

A cement plant, for example, has different operating conditions from a natural gas processing facility. A capture system must be designed for the conditions at the particular site.

2. Separating Carbon Dioxide

The capture system separates carbon dioxide from other gases or substances. Different technologies can perform this task, including chemical solvents, solid sorbents, membranes, and specialized cooling processes.

3. Preparing the Captured Carbon

After separation, the carbon dioxide may need to be purified, dehydrated, and compressed. These steps help prepare it for transportation or for a particular use.

4. Transporting Carbon Dioxide

Depending on the project, carbon dioxide can be moved through pipelines or transported using other suitable methods. Transportation infrastructure must be designed for the relevant pressure, volume, location, and safety requirements.

5. Storing or Using the Carbon

Captured carbon dioxide can be injected into suitable geological formations for long-term storage or used as a feedstock in selected products and industrial processes.

These pathways are not environmentally equivalent. Carbon dioxide used to produce synthetic fuel may be released when that fuel is burned, while carbon mineralized into a durable building material may remain stored for much longer.

6. Monitoring and Verification

Storage projects require appropriate monitoring, reporting, and verification. These activities help determine whether carbon dioxide remains contained and whether the project is achieving its intended environmental objectives.

Major Types of Carbon Capture Technology

Different technologies address different carbon sources and operating conditions. Understanding the distinctions is important when evaluating a company’s project or a new industry announcement.

1. Post-Combustion Carbon Capture

Post-combustion capture separates carbon dioxide from exhaust gases after fuel has been burned.

The technology may be installed at facilities such as industrial plants and certain power stations. Chemical solvents are among the established approaches, although researchers continue to investigate alternatives that could reduce costs and energy consumption.

A typical solvent-based system brings the exhaust gas into contact with a liquid that selectively absorbs carbon dioxide. The solvent is then processed to release the captured gas so that the solvent can be reused.

The process can be technically demanding because exhaust gas may contain large amounts of other gases and may require conditioning before entering the capture equipment.

2. Pre-Combustion Carbon Capture

Pre-combustion capture separates carbon dioxide before a fuel-processing system completes its energy-conversion process.

In certain industrial configurations, fuel is converted into a gas mixture that contains hydrogen and carbon monoxide. Further processing can convert carbon monoxide into additional hydrogen and carbon dioxide, allowing the carbon dioxide to be separated.

This approach is associated with particular industrial processes and power-generation configurations. It is not a universal solution for all facilities.

3. Direct Air Capture

Direct air capture, commonly called DAC, removes carbon dioxide directly from ambient air.

Unlike industrial capture, which can target a relatively concentrated source of carbon dioxide, direct air capture must process large volumes of air because atmospheric carbon dioxide is relatively dilute.

DAC systems commonly use liquid chemicals or solid sorbent materials to capture carbon dioxide. The system then uses energy to release the collected gas for storage or further processing.

Potential applications include removing historical carbon dioxide emissions from the atmosphere. However, the total climate benefit depends on energy use, construction, material requirements, operating costs, and the permanence of the storage pathway.

4. Membrane-Based Carbon Capture

Membrane technology uses specialized materials to separate carbon dioxide from other gases.

The gas mixture passes through or along a membrane, which allows certain components to move differently from others. Engineers are investigating new membrane materials that could improve separation performance and reduce energy requirements.

The suitability of membrane systems depends on gas composition, pressure, temperature, material durability, and the desired purity of the captured carbon dioxide.

5. Cryogenic Carbon Capture

Cryogenic capture uses cooling and other process-engineering techniques to separate carbon dioxide from industrial gas streams.

These systems may be appropriate for selected industrial conditions, but cooling can require substantial energy. The economic case depends on the gas composition, heat integration, process design, and operating environment.

The U.S. Department of Energy’s National Energy Technology Laboratory maintains information on research projects involving solvents, sorbents, membranes, and other capture technologies.

Why Carbon Capture Matters for American Industry

Carbon capture is attracting interest because several important industries face emissions-reduction challenges that cannot always be solved by switching to renewable electricity alone.

Cement Manufacturing

Cement production releases carbon dioxide through both fuel use and the chemical process that converts limestone into clinker, a key ingredient in cement.

Even if a cement plant replaces some fossil energy with lower-emission electricity or alternative fuels, process-related emissions may remain.

Carbon capture could help address some of these emissions by treating the exhaust gases from cement kilns. The practical results depend on capture efficiency, energy consumption, plant integration, and the availability of transportation and storage infrastructure.

Steel Production

Steel manufacturing uses several different production methods, and their emissions profiles vary.

Some facilities may reduce emissions through electrification, recycled steel, or lower-emission ironmaking technologies. Carbon capture may be relevant to selected production routes where substantial carbon dioxide emissions remain.

The best approach depends on the facility’s equipment, raw materials, energy supply, and long-term investment plans.

Chemical Manufacturing

Chemical plants can produce concentrated carbon dioxide streams during certain processes. Such streams may be suitable for capture, depending on their composition and operating conditions.

Captured carbon dioxide may be stored or used in selected applications, but the environmental benefit must account for the energy and materials required by the complete process.

Natural Gas Processing and Refining

Some natural gas processing facilities separate carbon dioxide from gas streams to meet product specifications. Capturing and managing this carbon dioxide can differ technically and economically from capturing dilute emissions in conventional exhaust gases.

Refineries also have multiple emission sources, making the design of a capture project dependent on the individual facility.

Direct Air Capture: Can Technology Remove Carbon Dioxide From the Atmosphere?

Direct air capture has attracted interest because it addresses carbon dioxide already present in the atmosphere rather than targeting only emissions from a specific industrial facility.

However, it is important to distinguish between capturing carbon dioxide and achieving durable carbon removal.

If a DAC facility captures carbon dioxide and stores it in an appropriate geological formation, the project may provide long-term removal, subject to its lifecycle emissions and storage performance.

If the captured carbon dioxide is instead converted into a product that quickly releases it back into the atmosphere, the project may provide a different benefit, such as replacing another raw material, but it does not necessarily deliver permanent carbon removal.

How a DAC Facility Operates

A typical direct air capture facility includes equipment to move air through a capture system, materials that selectively collect carbon dioxide, and processes that release the carbon dioxide for collection.

The captured gas can then be compressed and transported to a suitable storage site or a carbon-use facility.

DAC performance depends on the capture material, operating conditions, energy source, water availability, and the process used to regenerate the capture system.

US Direct Air Capture Hubs

The US Department of Energy has supported regional direct air capture hub development as a way to advance technology, infrastructure, and project integration.

A hub can bring together capture facilities, energy supplies, carbon dioxide transportation, geological storage, and supporting services.

This integrated approach may help developers assess how individual components work together at a larger scale. However, announced funding or engineering studies do not mean a hub is already operating at its proposed capacity.

The Department of Energy’s carbon management portfolio describes programs for carbon capture demonstrations, large-scale pilots, and regional direct air capture hubs.

Recent Carbon Capture Developments in the USA in 2026

American carbon capture activity spans industrial testing, geological storage planning, direct air capture studies, and policy oversight.

1. More Industrial Testing

On September 29, 2026, the National Carbon Capture Center reported that its technology testing program had surpassed 175,000 hours and evaluated more than 90 different carbon capture technologies.

The center provides facilities and technical expertise that allow developers to assess equipment performance, collect operating data, and determine whether a technology is ready for further engineering and commercial development.

These results illustrate the importance of testing systems under realistic operating conditions rather than relying entirely on laboratory experiments.

2. New Work on Carbon Storage and Utilization

Carbon capture projects require a destination for the captured gas. Geological storage projects therefore need to examine underground formations, injection systems, monitoring plans, transportation arrangements, and long-term responsibilities.

The Department of Energy’s National Energy Technology Laboratory maintains a database of projects covering carbon storage, capture, and related infrastructure.

For example, its project information includes work on geological characterization, pipeline planning, storage feasibility, and risk assessment. These activities are essential because a capture facility cannot deliver its intended result unless the carbon dioxide can be managed safely after separation.

3. Direct Air Capture Project Development

The Department of Energy’s project listings include studies intended to assess the feasibility of regional DAC hubs.

Such work can involve selecting capture technologies, evaluating energy sources, studying transportation and storage infrastructure, and preparing engineering and business plans.

These preparatory activities can help identify technical or financial barriers before developers commit to full-scale construction.

4. Greater Attention to Tax Credit Oversight

Federal incentives have played an important role in carbon capture investment decisions.

The Government Accountability Office’s August 2026 report on the Section 45Q carbon oxide sequestration credit identified administrative challenges, particularly for some carbon utilization projects. It also noted limitations in measuring the overall effectiveness of the incentive.

This matters because financial incentives can encourage investment, but effective oversight is necessary to assess whether public support is delivering the intended results.

How Captured Carbon Dioxide Can Be Used

Captured carbon dioxide is not always sent directly to permanent storage. It can also be used as an input in selected industrial processes.

Building Materials

Carbon dioxide can be incorporated into certain concrete and other construction products through processes that mineralize or otherwise retain the carbon.

The climate benefit depends on how much carbon remains stored, the emissions associated with production, and whether the product displaces a more emissions-intensive alternative.

Chemicals and Industrial Feedstocks

Captured carbon dioxide can serve as a feedstock for some chemicals and industrial products.

These applications may help replace other sources of carbon, but they require suitable conversion technology and an appropriate market for the resulting product.

Synthetic Fuels

Carbon dioxide can be combined with hydrogen to produce synthetic fuels in certain processes.

The lifecycle emissions of these fuels depend heavily on how the hydrogen is produced, the energy used for conversion, and the source of the carbon dioxide.

If the fuel is burned, the carbon dioxide will generally be released again. Therefore, this pathway should not be treated as equivalent to permanent geological storage.

Enhanced Oil Recovery

Some projects use injected carbon dioxide to help recover additional oil from underground formations. A portion of the injected carbon dioxide may remain underground, but the overall climate impact depends on the quantity retained, monitoring, and emissions associated with the additional oil produced.

Projects using this pathway require careful lifecycle assessment rather than assuming that all captured carbon results in a net environmental benefit.

Leading Organizations and Companies in the US Carbon Capture Industry

The carbon capture industry includes technology developers, engineering firms, industrial companies, research laboratories, and geological storage operators.

ExxonMobil

ExxonMobil has pursued carbon capture and storage projects, particularly around industrial facilities and the US Gulf Coast.

Large-scale projects may involve multiple industrial customers, pipelines, injection wells, and storage formations. Their progress depends on regulatory approvals, commercial agreements, infrastructure development, and public acceptance.

Carbon Engineering

Carbon Engineering developed direct air capture technology designed to remove carbon dioxide from ambient air. Its technology has been associated with efforts to develop large-scale atmospheric carbon removal.

The viability of any project using this approach depends on the capture system’s energy requirements, costs, construction schedule, and storage or utilization arrangements.

Climeworks

Climeworks is known for developing direct air capture systems. The company has helped bring public attention to the potential of removing carbon dioxide directly from the atmosphere.

DAC remains an emerging industry, and commercial projects must demonstrate that they can achieve durable carbon removal at an acceptable cost.

Linde and BASF

Linde and BASF have been involved in carbon capture engineering and process development. Their areas of expertise include industrial gas processing, chemical engineering, and systems designed to separate carbon dioxide from industrial emissions.

The performance of a capture project depends on its specific configuration, energy integration, and operating conditions.

National Laboratories and Universities

US national laboratories and universities play an important role in developing new capture materials, testing processes, modeling industrial systems, and evaluating geological storage.

Government-supported research can help reduce technical uncertainty and provide information needed by commercial developers.

A company’s involvement in carbon capture research should not automatically be interpreted as proof that a particular technology is commercially mature. Readers should distinguish between laboratory testing, pilot operation, demonstration projects, and fully commercial deployment.

Benefits of Carbon Capture Technology

Carbon capture can provide several potential benefits when applied to suitable facilities and combined with effective carbon management.

Reduced Emissions From Selected Industrial Sources

Capture systems can separate some carbon dioxide that would otherwise enter the atmosphere. The net benefit depends on capture performance and the emissions generated by the capture and storage process itself.

Support for Difficult-to-Decarbonize Industries

Some industrial processes produce carbon dioxide as part of their chemistry. Carbon capture may offer a way to address a portion of these emissions while other technologies continue to develop.

Potential for Long-Term Carbon Removal

Direct air capture combined with durable storage may remove carbon dioxide that is already in the atmosphere. This is different from simply preventing a new emission.

Technology and Manufacturing Development

Research and deployment can create opportunities for engineering services, specialized materials, equipment manufacturing, pipeline construction, monitoring, and geological assessment.

Better Understanding of Industrial Emissions

Capture projects require detailed measurement of gas streams, operating conditions, and carbon flows. This information can help companies better understand their emissions and identify additional opportunities for efficiency improvements.

These potential benefits should be assessed against project costs, energy requirements, environmental risks, and alternative ways to reduce emissions.

Major Challenges Facing Carbon Capture in America

Despite ongoing development, carbon capture faces significant obstacles.

1. High Costs

Capture equipment, energy supply, compression, pipelines, and storage infrastructure can require substantial investment.

Costs vary by source. A relatively concentrated carbon dioxide stream may be less expensive to capture than a dilute industrial exhaust or ambient air.

2. Additional Energy Requirements

Carbon capture systems often require energy to separate and compress carbon dioxide. If that energy comes from a high-emission source, it can reduce the overall climate benefit.

Careful engineering and lower-emission energy supplies can help improve performance, but the full energy balance must be evaluated.

3. Transportation Infrastructure

Large capture projects may require pipelines or other transportation systems connecting industrial facilities with storage sites.

Infrastructure development involves engineering, land access, permitting, emergency planning, and coordination among multiple project owners.

4. Storage Site Selection

Geological storage requires suitable underground formations and a detailed understanding of their properties.

Developers need to evaluate the geology, injection conditions, monitoring requirements, and potential risks. Storage sites also require appropriate permits and long-term management arrangements.

5. Community Concerns

Communities near pipelines, industrial facilities, or injection sites may have concerns about safety, land use, water resources, and emergency response.

Transparent engagement and reliable environmental information are important parts of responsible project development.

6. Measuring Real Climate Benefits

The amount of carbon dioxide captured is not the same as the amount of emissions avoided or permanently removed.

A full assessment should account for energy use, construction, transport, storage performance, potential leakage, and the final use of captured carbon.

This is especially important when projects receive public financial support or make environmental claims to customers.

The Future of Carbon Capture Technology in the USA

The next stage of US carbon capture development will likely depend on whether companies can demonstrate reliable performance under commercial conditions.

Several areas will influence progress.

Improved capture materials: New solvents, membranes, and sorbents may help reduce the energy needed to separate carbon dioxide.

More industrial demonstrations: Pilot projects can reveal how capture systems perform under real operating conditions and help developers improve their designs.

Direct air capture development: DAC projects may continue to test approaches for reducing costs, improving energy efficiency, and integrating durable storage.

Carbon transportation and storage networks: Shared infrastructure could help connect multiple industrial sources with suitable storage locations, provided that the projects meet technical, economic, and safety requirements.

Better measurement and verification: Reliable monitoring can help investors, regulators, and the public distinguish between captured carbon, permanently stored carbon, and emissions reductions achieved elsewhere.

Clearer financial accountability: Federal and state incentives may influence project economics, but transparent reporting and oversight are necessary to evaluate their effectiveness.

Carbon capture is unlikely to be the best solution for every source of emissions. In some cases, energy efficiency, electrification, renewable power, alternative production processes, or material substitution may offer a more practical path.

The strongest projects will be those that address a clearly defined problem, demonstrate measurable environmental benefits, and fit into a broader emissions-reduction strategy.

Conclusion

Carbon capture technology is an important area of industrial research and development in the United States. Advances in chemical solvents, membranes, direct air capture, carbon transportation, and geological storage are expanding the range of approaches available to companies seeking to manage carbon dioxide emissions.

The industry is also learning that successful deployment requires more than capture equipment. Reliable energy supplies, suitable storage locations, careful measurement, sound project economics, effective regulation, and community engagement are all essential.

For American manufacturers, energy companies, and technology developers, carbon capture may provide useful options for addressing certain emissions that are difficult to eliminate through other means. Direct air capture may also contribute to atmospheric carbon removal if projects achieve durable storage and credible lifecycle benefits.

Ultimately, the future of carbon capture in the USA will depend on proven performance rather than announcements alone. Transparent data, responsible implementation, and careful comparisons with alternative technologies will be critical to determining where carbon capture can deliver genuine value.
