Is carbon capture an efficient way to tackle CO2?
In Iceland a new plant is capturing and storing CO2 directly from the atmosphere.
Capable of removing 36,000 tonnes of CO2 a year, an amount similar to taking 8,000 petrol cars off the road, Mammoth is almost 10 times larger than Climeworks’ first commercial plant called Orca. Eventually Mammoth will be dwarfed by US-based Project Cypress, which breaks ground in 2026, and which Climeworks hopes will remove up to a million tonnes of CO2 annually, using new technology which it claims will be cheaper and more energy efficient. “We release about 40 billion tonnes of carbon dioxide into the atmosphere every year, so this [DAC] won't make a dent in the big problem,” says Dr Sólnes.
