CAPTURE PROCESSES CO2 capture processes from power production fall into three general categories: (1) flue gas separation; (2) oxy-fuel combustion in power plants; and (3) pre-combustion separation. Based on the results of major economic studies available in the literature adjusted to a common economic basis, Figure 4 summarizes the present cost of electricity (COE) from three types of CO2 capture power plants: Integrated Gasification Combined Cycles (IGCC), Pulverized Coal Fired Single Cycle (PC), and Natural Gas Combined Cycles (NGCC). These targets of opportunity will either have very inexpensive capture costs (from non-power sources like natural gas processing, ammonia production, etc.) or be able to claim a by-product credit (e.g., EOR).

One way to make coal cleaner is carbon capture and storage, or CCS. In CCS, which can be used at both coal and natural gas plants, CO2 gas is captured before it

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.

Carbon capture, utilization and storage (CCUS) is a set of methods to stop carbon dioxide reaching the atmosphere or remove what is already there. To put that into perspective, stand-alone CCUS facilities can capture around 1-2 million tonnes of carbon dioxide per year. CCUS hubs are likely to store an average of 10 million tonnes of carbon dioxide per year by 2030, so around four hubs each quarter would need to be built every year from 2024 to 2030 to meet the IEA scenario. In the latest IPCC AR6 reports, nearly all the 97 scenarios that keep global warming below 1.5°C with no or limited overshoot include CCUS in some form – for industries, power and for carbon removals – with 665 gigatonnes of carbon dioxide cumulatively captured and stored by 2100. These two uses – EOR and natural gas processing – still account for most of the 40 million tonnes of carbon dioxide captured globally each year.

* Carbon capture, use, and storage technologies can capture more than 90 percent of carbon dioxide (CO2) emissions from power plants and industrial facilities. This natural gas processing plant serves ExxonMobil, Chevron, and Anadarko Petroleum carbon dioxide pipeline systems to oil fields in Wyoming and Colorado and is the largest commercial carbon capture facility in the world at 7 million tons of capacity annually. The first ethanol plant to deploy carbon capture, it supplies 170,000 tons of carbon dioxide per year to Chaparral Energy, which uses it for EOR in Texas oil fields. Carbon dioxide from a gas processing plant owned by DTE Energy is captured at a rate of approximately 1,000 tons per day and injected into a nearby oil field operated by Core Energy in the Northern Reef Trend of the Michigan Basin. This project involves capturing carbon dioxide from natural gas processing for use in enhanced oil recovery in the Lula and Sapinhoá oil fields.

* 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.

Geologic carbon sequestration, also called carbon storage, involves storing CO2 deep underground in porous rock formations. In this approach
