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.

The carbon-removal approach would extract CO2 from other gases in the atmosphere by changing it into other forms of carbon (such as carbonate) through photosynthesis or artificial “scrubbing.” This separated carbon then would be either sequestered in biomass at the surface or transported away for storage in the ocean or underground. These include carbon burial, ocean fertilization, biochar production, and scrubbing towers or “artificial trees.”. Carbon burial, more commonly known as carbon capture, utilization, and storage (CCUS), involves the pumping of pressurized CO2 into suitable geological structures (that is, with gas-tight upper layers to cap the buried carbon) deep underground or in the deep ocean (*see* carbon sequestration). The carbon-burial process could also make use of carbon dioxide captured from the atmosphere using scrubbers (*see below* Scrubbers and artificial trees). Direct air captureCollector containers for capturing carbon dioxide from the atmosphere at the Orca plant in Hellisheiði, Iceland. Another form of carbon capture, called direct air capture (DAC), would involve the use of scrubbing towers and so-called artificial trees.

For example, geoengineering includes the removal of carbon dioxide from the atmosphere (also called Carbon Dioxide Removal – CDR) through methods such as direct air capture and storage, ocean iron fertilization, or ocean alkalinity enhancement. These activities are referred to as **Solar Geoengineering** or **Solar Radiation Modification (SRM).** Most proposed solar radiation modification techniques involve adding material to the atmosphere to increase the amount of incoming sunlight reflected back to space. Marine solar radiation management (mSRM) techniques, on the other hand, involve adding materials to ocean waters, sea ice, or the lower atmosphere to increase the amount of solar radiation reflected at or near the ocean's surface to limit surface warming or sea ice melt. * *Marine Cloud Brightening (MCB)* – adding particles, such as sea spray, to the lower atmosphere (near the surface) to increase the reflectivity of clouds over the ocean. Another subset of geoengineering activities intends to cool the Earth by intentionally modifying the concentration of certain gases in the atmosphere, including carbon dioxide.

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.

# The controversy of carbon geoengineering. ## Supporters insist removing carbon from the atmosphere is necessary to reach net zero, but critics call it a ‘dirty trick’ from fossil fuel producers. Carbon geoengineering is the removal and durable storage of carbon emissions from the atmosphere aimed at helping to limit the global temperature rise. While carbon dioxide removal technologies could support efforts to reach net zero emissions by 2050, they remain controversial and critics warn that fossil fuel producers could use them to justify business as usual. ## To continue reading. ## Read next. ### US DoE cuts threaten long-term energy goals, report warns. ### Corporate America’s DEI retreat predates Trump. ### Canadian investors stay focused on ESG integration, study shows.

Big Oil.3 Because DAC demands large quantities of energy, it could easily use up much of the renewable energy needed to electrify vehicles and the heating of Desperate Measures Carbon capture is rapidly being inserted into both federal and state legislation, despite the fact that the technology is unproven as a safe way to sequester carbon, and is also inordinate ly expensive. Industry falsely claims that carbon capture can be used to boost local economies, but we know that profits will stay in the pockets of Big Oil, while the fossil fuel industry continues to pollute our communities and raise the Earth’s temperature through carbon emissions.
