Direct air capture and how can it fight climate change
As the need for climate action intensifies, governments and industries are exploring how to remove carbon dioxide (CO2) from the atmosphere.
The U.S. government has offered $3.5 billion in grants to companies that will capture and permanently store the gas using a process known as Direct Air Capture (DAC).
DAC technology uses chemical reactions to remove carbon dioxide from the air, allowing it to then be stored in underground caverns or used in applications such as making concrete.
The main selling point of DAC compared with carbon capture technology used at industrial sites is that it can pull historical emissions out of the sky.
DAC technology uses chemical reactions to remove carbon dioxide from the air, which can then be stored in underground caverns or used in products or applications such as making concrete or aviation fuel.
The world's largest operating DAC plant, Climeworks' Orca plant in Iceland, can remove 4,000 tonnes of CO2 a year, which is then stored deep underground.
The U.S. programme is seeking to fund large-scale plants capable of removing a million tonnes a year.
Natural methods of carbon removal such as planting trees and forest management are expected to play a huge role in helping combat climate change. Doing so is relatively inexpensive, at less than $50 per ton, according to the World Resources Institute, compared to technology such as DAC, which currently costs in the high triple digits per ton.

Many scientists, however, believe technical solutions will be needed, partly due to the amount of land that would have to be taken up if all the required removals were made through using trees.
