Among the solutions considered by some to limit global warming, there is the capture and storage of carbon dioxide (CO2). And indeed, the largest factory of its kind was commissioned yesterday, near Iceland.
Is history being written on the Icelandic side? This Wednesday, September 8, 2021, the world’s largest collection plant(CO2) in the atmosphere then its has been put into service. The Swiss Climeworks and the Icelandic company Carbfix – who are at the origin of it – announce an extraction capacity of 4,000 tonnes of CO2 per year. This is a lot, when we know that the fifteen other plants of this type currently in operation capture a total of some 9,000 tonnes of CO.2 per year. But it remains little compared to global CO2 estimated at over 30 billion tonnes in 2020. However, some estimate the effort required to limit anthropogenic global warming.
The Orca factory – in reference to the Icelandic meaning– therefore aspires to . At the heart of eight large containers. To big of fans that suck the in a collector equipped with filters. Once the collector is saturated, the temperature is increased to release and isolate a CO2 very concentrated. It is then mixed with water and then injected into the subsoil, some 1,000 meters deep. It will eventually turn into a rock.
Other CO capture / storage plants2 future ?
Rest assured, the system is supplied with renewable energy by alocated nearby. But it is not only energy intensive. It is also expensive. A defect that the designers hope to reduce with its large-scale industrialization. More and more companies and even individuals seeking to reduce their carbon footprint.
Another project of the same type, by the way. That of the American oil company Occidental. It is developing a large direct CO capture installation2 intended to extract this time a million tonnes ofof our atmosphere per year. All in the Texas oilfields region.
