Swiss start-up Climeworks, which specializes in capturing CO₂ directly from the air, has partnered with Icelandic carbon storage firm Carbfix to develop a plant that sucks out up to 4,000 tons of CO₂ per year.
That's the equivalent of the annual emissions from about 790 cars. Last year, global CO₂-emissions totaled 31.5 billion tonnes, according to the IEA.
Direct air capture is one of the few technologies extracting CO₂ from the atmosphere and is viewed by scientists as vital to limit global warming, blamed for causing more heatwaves, wildfires, floods and rising sea levels.
The Orca plant, a reference to the Icelandic word for energy, consists of 8 large containers similar in looks to those used in the shipping industry, which employ high-tech filters and fans to extract CO₂.
Direct air capture is still a fledgling and costly technology, but developers hope to drive down prices by scaling up as more companies and consumers look to reduce their carbon footprint.
There are currently 15 direct air capture plants operating worldwide, capturing more than 9,000 tonnes of CO₂ per year, according to the IEA.
U.S. oil firm Occidental Petroleum Corp. is currently developing the largest direct-air-capture facility, to pull 1 million tonnes per year of CO₂ from the open air near some of its Texas oil fields in the Permian Basin.
Climeworks, which recently signed a 10-year carbon removal purchase agreement with major insurance firm Swiss Re, also offers a subscription service, which allows consumers to pay for carbon removal through monthly payments.
