New direct air capture plant 'Mammoth' opens in Iceland

A new direct air capture plant, called Mammoth, has opened in Iceland to remove carbon dioxide from the atmosphere using chemicals. The plant is powered by Iceland's geothermal energy and will transport the captured carbon underground for permanent storage. The technology is seen as an important step in the fight against climate change, but some critics have raised concerns about its cost, energy consumption, and potential to prolong fossil fuel production.
