Carbon dioxide capture technology and its mechanism

Types of carbon capture technology

1. Carbon sink

The natural form of CCS is called a ‘carbon sink’, which is the vast space where natural habitats absorb CO.₂ From the atmosphere – these include forests, seas, grasslands and wetlands.

Environmentalists as well as scientists recognize that the conservation and cultivation of carbon sinks can increase the amount of carbon taken from the atmosphere in the shortest possible time.

Especially grasslands and wetlands convert carbon stocks much faster, and coastal wetlands have higher carbon stocks per hectare than other habitats such as forests.¹

Where forests are used, experts believe that certain types of trees, such as birches and willows, are best suited for carbon capture on land because they absorb more CO.₂ compared to other tree species.

Storing carbon dioxide in ancient peatlands One method that is being worked on to biologically capture carbon is Conservation and Restoration of Ancient Peat Bogs It is located near the substation in South Wales. The 15 hectares of wetlands store 32,000 tonnes of carbon dioxide, equivalent to the average annual emissions of 22,000 gasoline vehicles. By restoring it, the conditions for rare butterflies and plants to thrive were created.

2. Saline aquifer

Deep saline aquifers are underground formations. A vast expanse of porous sedimentary rock filled with brine. CO₂ In fact, saline aquifers have been identified as having the greatest storage potential among all other forms of engineered CCS.

The ‘Endurance’ aquifer, located in the North Sea off the coast of Great Britain, is one such formation, about 1 mile (1.6 km) below the seafloor. Roughly the size of Manhattan Island and the height of The Shard or the Empire State Building, its porous composition allows carbon dioxide to be injected inside and stored safely for thousands of years.

Several large saline aquifers are currently being used for CCS purposes in the United States. citronel project in Alabama. Succeeded in storing more than 150,000 tons of CO during the three-year trial period₂ Captured from a nearby pilot facility.

3. Huge air filter

Carbon capture technologies are still being developed globally, with countries developing strategies to meet their own net-zero targets. For example, in China, a company has developed an experimental commercial air filter. This is a giant tower that removes pollutants on a large scale. These giant air towers purify the air by drawing it into heated glass chambers using solar power to create a greenhouse effect. This hot air is forced through a series of filters and up the tower before being released into the atmosphere as clean air.

One such gigantic air purifier tower in Xi’an reportedly purifies more than 353 million cubic feet of air daily, dramatically improving local air quality. I’m here. The manufacturer believes he is on the verge of developing an even larger tower that could clean enough air for a small city on a daily basis.

4. Ionic liquids: future carbon capture technology?

The latest advances in CCS technology involve new types of liquids that are highly effective in absorbing CO.₂Two-dimensional “ionic” liquids have molecular structures that allow for higher percentages of CO₂ be absorbed. Scientists believe that “editing” liquids offer more precise control in chemical engineering processes and are considered environmentally friendly.
