Mitigating climate change and its impacts will require an unprecedented global effort in the coming decades – and savings alone are unlikely to be enough; too much carbon dioxide (CO2) has already been released into the atmosphere. Swiss inventors therefore want to take it back and have started using the largest CO2 vacuum cleaner in the world in Iceland: the Mammut system.
The Mammut factory is the second CO2 vacuum cleaner in Iceland: in 2021, the Swiss start-up Climeworks opened a pilot plant there that removes CO2 from the atmosphere and stores it in porous volcanic rock. The Orca facility would suck 4,000 tons out of the atmosphere every year – and it was a success. That is why Climeworks has now opened an even larger facility: Mammut. The aim is to filter and store up to 36,000 tonnes of carbon dioxide from the air annually. That would amount to 15,600 Austrians producing traffic exhaust fumes in one year – 2.3 tonnes per person, according to the mobility club VCÖ. But CO2 extraction and storage technology still has a catch.
