World’s Largest Carbon Capture Plant

Published: 11th May, 2024

Context

The World’s largest carbon capture plant, called the Mammoth direct air capture and storage (DAC+S) plant, is now operational in Iceland (Hellisheiði geothermal park).

About

  • The purpose of this plant is to capture carbon dioxide (CO2) from the air using a process called direct air capture (DAC).
  • Large fans pull air into the plant, where chemicals remove the carbon dioxide. Once captured, the CO2 can be stored deep underground, reused, or turned into solid products.
  • The Mammoth plant is expected to remove up to 36,000 tonnes of CO2 from the air annually.
  • Unlike carbon capture methods that capture emissions at their source, DAC removes CO2 directly from the air.

Fact Box: Carbon capture and storage

  • Carbon capture and storage (CCS) involves capturing carbon dioxide (CO2) at emission sources, transporting and then storing or burying it in a suitable deep, underground location.
