The world's largest plant that sucks carbon dioxide directly from the air and deposits it underground will begin operating on Wednesday, the company behind the nascent green technology said.
Swiss start-up Climeworks AG, which specializes in capturing carbon dioxide directly from the air, has teamed up with Icelandic carbon storage firm Carbfix to develop a plant that sucks up to , tonnes of CO per year.
That's the equivalent of the annual emissions of about cars. Last year, global CO emissions totaled billion tons, according to the International Energy Agency (IEA).
Direct air capture is one of the few technologies that remove carbon dioxide from the atmosphere and is considered vital by scientists to limit global warming, which is blamed for causing more heat waves, wildfires, floods and rising temperatures. sea level.

How is carbon dioxide removed from the atmosphere? One of the key ways to stop global warming is through direct air capture technology.
The Orca plant, a reference to the Icelandic word for energy, consists of eight large containers similar in appearance to those used in the shipping industry, which use high-tech filters and f C Level Executive List ans to extract carbon dioxide.
The machines consist of modular CO₂ collectors that can be stacked to build machines of any size. Climeworks direct air capture machines are powered solely by renewable energy or waste energy. Gray emissions are below %, meaning that for every tonnes of carbon dioxide that machines capture from the air, at least tonnes are permanently removed and only up to tonnes are re-emitted. The isolated carbon is then mixed with water and pumped deep underground, where it slowly turns into rock. Both technologies are powered by renewable energy from a nearby geothermal power plant.
How is carbon captured from the air and removed from the atmosphere?
CO₂ collectors selectively capture carbon dioxide in a two-step process.
The air is introduced into the collector with a fan. Carbon dioxide is captured on the surface of a highly selective filter material inside the collectors.
Once the filter material is full of carbon dioxide, the collector is closed. We increase the temperature between and ° C; this releases carbon dioxide. Finally, we can collect this high-purity, high-concentration carbon dioxide.

From Air to Earth
“Carbon dioxide removal is a term used to describe approaches that permanently remove carbon dioxide from the air. This means that historical emissions are physically removed from the air. There are many options around the world for storing carbon dioxide after it has been captured from the air. We focus on natural sinks, such as underground carbon dioxide mineralization. “Natural CO₂ storage in pure or dissolved form serves as a model for managed CO₂ storage in geological formations.” Climeworks AG Web.
Direct air capture remains a nascent and expensive technology, but developers hope to reduce prices by increasing scale as more businesses and consumers look to reduce their carbon footprint.
The world's largest plant capturing carbon from the air will be installed in ICELAND, however there are currently direct air capture plants in operation around the world, capturing more than , tonnes of CO a year, according to the IEA.
US oil company Occidental is currently developing the largest direct air capture facility , to extract million tonnes per year of carbon dioxide from the open air near some of its Texas oil fields.
Climeworks, which recently signed a -year carbon removal purchase agreement with insurance major Swiss Re (SRENH.S), also offers a subscription service that allows consumers to pay for carbon removal through monthly payments.
