The video above is the shortest, clearest primer we could find to explain how this machine technology works. With Orca now on we will get the chance to see how much promise this process holds for carbon capture’s machine approach versus the tree approach, which we now know needs some reconsideration:
Operators say the Orca plant can suck 4,000 tonnes of CO2 out of the air every year and inject it deep into the ground to be mineralised
The world’s largest plant designed to suck carbon dioxide out of the air and turn it into rock has started running, the companies behind the project said on Wednesday.
The plant, named Orca after the Icelandic word “orka” meaning “energy”, consists of four units, each made up of two metal boxes that look like shipping containers.
Constructed by Switzerland’s Climeworks and Iceland’s Carbfix, when operating at capacity the plant will draw 4,000 tonnes of carbon dioxide out of the air every year, according to the companies.
According to the US Environmental Protection Agency, that equates to the emissions from about 870 cars. The plant cost between US$10 and 15m to build, Bloomberg reported.
To collect the carbon dioxide, the plant uses fans to draw air into a collector, which has a filter material inside…
