On March 30, 2023, under the pen of Alexandre Shields, The duty taught us that hundreds of millions of dollars would go to develop carbon capture and storage (CCS) technologies with only a brief indication that this technology is inefficient, pointing out, quoting the 2022 IPCC report, that “the implementation The implementation of CCS currently faces technological, economic, institutional, ecological, environmental and socio-cultural obstacles”. Let us try to illustrate some of these difficulties.
Oil companies extract about a million barrels of oil a day, which they would like to replace by burying the amount of carbon they contain in their place. It is therefore necessary, for each barrel, to extract a hundred kilograms of CO2 of the atmosphere. CO2 being a light gas, to assemble 100 kg of it, it is necessary to filter a volume of air of approximately one million cubic meters. If a stadium-sized plant (100 meters by 100 meters) draws in air to separate CO2this plant must suck in 100 cubic meters of air per square meter.
Doing this in a day is quite possible, but this calculation only applies to one barrel. This operation must be repeated a million times a day.
CCS technologies are not only inefficient, they are impractical and utopian. Throwing our money out the window or into the CSCs, same result.
