Carbon capture and storage is a technology that captures the carbon dioxide from burning fossil fuels before it is released to the atmosphere.
Carbon Capture and Storage (CCS) technology was originally developed by the oil industry to recover difficult-to-access deep oil reserves, and was used for Enhanced Oil Recovery (EOR). [2] Although CCS leads to the extraction and combustion of more fossil fuels, carries significant environmental risks, such as carbon dioxide escaping through leaks, is costly and technologically challenging, it is presented as a “climate technology” as a means of capturing climate finance.

Different options to try to reduce overall CO2 emissions are being investigated, but the main way to reduce CO2 emissions from large industrial sources is called carbon capture and storage, or CCS. CO2 can be captured from large sources, such as power plants, natural gas processing facilities and some industrial processes. Thus even though CCS would increase the cost of electricity from a biomass power plant, customers would know that electricity produced there would actually be reducing the CO2 content of the atmosphere, making this technology particularly attractive. The concept is to capture CO2 produced by burning coal in power stations, compress it, pipe it away from the plant and then store it deep underground. Most co-firing power plants burn solid biomass like wood and agricultural waste along with coal, but some can burn a mix of natural gas and biogas. A fossil-fuel power plant is one that burns fossil fuels such as coal, natural gas or petroleum (oil) to produce electricity.
# What is Carbon Capture and Storage (CCS)? Carbon Capture and Storage, or CCS, is a suite of technologies that captures CO2 from exhaust gases or the atmosphere. To tackle this, scientists and engineers have developed a suite of technologies known as **Carbon Capture and Storage (CCS)**. Carbon Capture and Storage, or CCS (also called CCUS – carbon capture, utilisation and storage), is a suite of proven technologies that help us capture CO2 from industrial exhaust gases or directly from the atmosphere. A diagram showing how Carbon Capture and Storage (CCS) works. Geological Carbon Storage is the process of storing CO2 permanently in porous rock at least 800m underground. * **It enables negative emissions** – When combined with bioenergy, waste-to-energy or direct air capture, these technologies can remove more CO2 from the atmosphere than they emit. According to the Global CCS Institute, as of October 2025, 77 commercial carbon capture and storage projects were operating, capturing 64 million tons of CO2 per annum.
In short, CCS is the process of capturing carbon from the emitting source (like a power plant) before it reaches the atmosphere, then injecting the carbon deep
* 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) technologies: Evaluating the effectiveness of advanced CCUS solutions for reducing CO2 emissions. This review provides a comprehensive examination of Carbon Capture, Utilization, and Storage (CCUS) technologies, focusing on their advancements, challenges, and future prospects. It begins with an overview of carbon capture methods, including pre-combustion, post-combustion, and oxy-fuel combustion techniques, highlighting recent technological improvements and associated challenges. The review then explores various carbon utilization strategies, such as chemical conversion, biological processes, and mineralization, discussing emerging technologies, potential applications, and the economic and environmental benefits of utilizing captured CO2. The discussion on carbon storage covers geological options like saline aquifers and depleted oil and gas fields, as well as recent advancements in monitoring and safety measures. In addressing the integration and optimization of CCUS systems, it evaluates the synergies between capture, utilization, and storage, includes techno-economic analyses of integrated systems, and presents case studies of successful CCUS projects. The review also identifies key research gaps, explores innovation potential, and provides strategic recommendations for advancing CCUS adoption.
