carbon capture, utilization, and storage
Also known as: CCUS, greenhouse gas capture, utilization, and storage, carbon capture, storage and utilisation, carbon capture and storage, carbon capture, storage, and use technologies
synthesized from dimensionsCarbon Capture, Utilization, and Storage (CCUS) is a comprehensive suite of technologies designed to mitigate greenhouse gas emissions by intercepting carbon dioxide at its source—typically industrial-scale plant processes—or by removing it from the atmosphere through natural processes like bio-crops. Once captured, the carbon dioxide is transported and either permanently sequestered in geological formations or repurposed for industrial utilization Carbon capture and storage technology definition.
At its core, CCUS functions as a strategic intervention in the global energy transition. By reducing the carbon footprint of fossil fuels carbon footprint of fossil fuels, the technology enables deep carbon reductions enabling deep carbon reductions that are difficult to achieve through electrification alone. It is frequently categorized alongside other decarbonization strategies, such as substitution technologies and geoengineering carbon capture and sequestration, serving as a critical tool for addressing the environmental threats posed by industrial emissions environmental threats from emissions.
The significance of CCUS lies in its ability to provide on-demand, low-carbon power that complements variable renewable energy sources like wind and solar. Much like nuclear energy, CCUS offers a reliable baseline, ensuring grid stability while facilitating the transition away from high-emission energy systems. It is widely regarded by organizations such as the Center for Climate and Energy Solutions as a necessary component for achieving net-zero emissions targets.
While CCUS is essential for decarbonization, it is not positioned as a replacement for other climate strategies. Instead, it operates in tandem with energy efficiency measures and the expansion of non-polluting energy sources. By integrating capture technologies with efficient conversion processes and clean energy infrastructure, CCUS provides a multifaceted approach to managing the carbon cycle, bridging the gap between current industrial reliance on fossil fuels and a sustainable, low-carbon future.

Carbon capture, utilization, and storage (CCUS), also referred to as carbon capture and sequestration (CCS), is a critical technology for reducing the carbon footprint of fossil fuels through efficient conversion and clean coal integration, complementing variable renewables like wind and solar for deep decarbonization low-carbon generators on demand, and enabling blue hydrogen via steam methane reforming transitional decarbonization strategy. It forms a foundational pillar alongside energy efficiency, electrification, and renewables in global strategies per Williams et al. four decarbonization pillars and a consensus in academia, governments, and countries global decarbonization consensus. Chinese classifications by the government include it in primary green low-carbon tech fossil fuel decarbonization, with Wang et al. highlighting it as a key area new energy categories. Applications span power, heavy industries like cement and lime industry decarbonization, and hydrogen, where a Nuclear Energy Agency (NEA) study projects LCOH for SMR-CCUS at $2-5.87/kg-H2 by 2035 NEA LCOH estimates, though least affordable at $45/MWh natural gas per NEA SMR-CCUS affordability. Globally, operating projects capture 50 Mt CO2/year, potentially 240 Mt including construction current capture volumes, projected to 8% of emissions by 2050 net-zero scenario. China leads patents (50% 2003-2022) with government R&D support China patent dominance, targeting 7.68% emission cuts by 2040 China CCUS contribution, but lags in quality vs. US/EU quality disparity. The US leads with ~50% of projects/revenue US project leadership, driven by Section 45Q tax credits per-ton subsidies and financing pipeline financing impact. EU commits via Green Deal EU Green Deal inclusion, Innovation Fund, and ETS reforms EU funding mechanisms, with >100 proposed projects by 2023 Europe project pipeline. Challenges include slow deployment below expectations deployment lag, public trust deficits, geologic limits geographic constraints, liability/permitting scaling hurdles, and early-stage readiness market readiness stage. Strategies emphasize clusters industrial clusters, efficiency gains energy efficiency reductions, and innovations like supercritical CO2 cycles future capture techs.
