Each of its carbon-sucking units is the size of a shipping container, yet the world’s largest direct air capture machine – the Orca plant in Iceland – only captures and stores about 4,000 tonnes of CO₂ a year. That’s about three seconds’ worth of global emissions.
This seems really a bit pointless, we would need so many of these to actually make any difference at all, and they are using a lot of energy to do it.
We really need to reduce the amount of carbon that we are creating by a lot before we think about using this kind of solution to clean what is left up.
