Explore the evolution of carbon capture technologies, their commercial potential, and challenges in scaling, costs, and efficiency gains.
Stanford Center for Carbon Storage. Stanford Center for Carbon Storage Energy Science & Engineering Energy Science and Engineering. # Carbon Capture, Utilization, and Storage: An Update. Recent progress in carbon capture, utilization, and storage (CCUS) is reviewed. Considerable research effort has gone into carbon dioxide (CO2) capture, with many promising separation processes in various stages of development, but only a few have been tested at commercial scale, and considerable additional development will be required to determine competitiveness of new technologies. Future deployment of CCUS will depend more on cost reductions for CO2 separations, development of new markets for CO2, and the complexities of project finance than on technical issues associated with storage of CO2 in the subsurface.

Carbon Capture and Storage (CCS) encompasses a suite of technologies designed to reduce CO2 emissions from combustion of fossil fuels and other
CCUS, which typically involves capturing CO₂ from the source before moving it to permanent underground storage or reusing it, faces challenges in yielding an economic return and operating in an emerging regulatory landscape. For its part, the US has a well-developed CO₂ transport industry, and other developments—like capture hubs and transport networks with shared storage infrastructure and CCUS-related mergers—are facilitating economies of scale in the country. In the European Union (EU), the Net-Zero Industry Act aims to have 50 million tons per year of CO₂ storage developed by 2030, while the US’s Inflation Reduction Act offers a range of tax credits for different forms of carbon capture. However, efforts are in place to promote international standardization; for example, the ISO Technical Committee 265 is working on “Standardization of design, construction, operation, environmental planning and management, risk management, quantification, monitoring and verification, and related activities in the field of carbon dioxide capture, transportation, and geological storage.”.
* The **United States** announced important opportunities in 2023 that are expected to boost CCUS project development, including USD 1.7 billion for carbon capture demonstration projects and USD 1.2 billion for direct air capture (DAC) hubs under the 2021 Infrastructure Investment and Jobs Act. Close to ten large-scale (capture capacity over 100 000 tCO2/year, and over 1 000 tCO2/yr for DAC applications) capture facilities entered operation in 2023, including the Blue Flint ethanol project, Linde Clear Lake capture facility, and Heirloom and Global thermostat’s first 1,000 tCO2/yr facilities in the United States, and four projects in China (the Jiling Petrochemical CCUS facility, the CNOOC Enping oil field, the first phase of the Guanghui Energy CCUS integration project and the China Energy Taizhou power plant). The database covers all CCUS projects commissioned since the 1970s with an announced capacity of more than 100 000 t per year (or 1 000 t per year for direct air capture facilities) and a clear scope for reducing emissions.

Carbon capture, utilization and storage (CCUS), also referred to as carbon capture, utilization and sequestration, is a process that captures carbon dioxide emissions from sources like coal-fired power plants and either reuses or stores it so it will not enter the atmosphere. Carbon dioxide storage in geologic formations includes oil and gas reservoirs, unmineable coal seams and deep saline reservoirs -- structures that have stored crude oil, natural gas, brine and carbon dioxide over millions of years. The Energy Department supports research and development of tools to assess the environmental fitness and safety of -- and predictability of future capacity within -- proposed geologic storage sites. We’re also developing models that simulate the flow of stored carbon dioxide, to help understand and predict chemical changes and effects of increased pressure that may occur.
Carbon capture and storage is forecast to grow fourfold to 2030, and technological advances and government approval will be key to scaling
Current carbon capture projects can handle around 1% of current CO2 emissions. That's not enough to change the trajectory of climate change.
