Switzerland-based Climeworks has just launched another of its second-generation Direct Air Capture plants (DAC-3) in Troia, Apulia in Italy.
Climeworks has been developing the technology since 2009 and commissioned its first industrial-scale CO2 capture unit in late 2014 dubbed the ‘CO2 Collector’, which captures 50 tonnes of CO2 per year.
Its plants capture atmospheric carbon with a filter; air is drawn into the plant and the CO2 within the air is chemically bound to the surface of a sorbent (the filter). Once the filter is saturated with CO2 it is heated (using mainly low-grade heat as an energy source) to around 100°C. The CO2 is then released from the filter and collected as concentrated CO2 gas, which can then be purified and delivered as high purity CO2 for carbonating beverages, for example.
Climeworks then pioneered and launched the world’s first commercial-scale direct air capture (DAC) plant in Hinwil, Switzerland in 2017, featuring the patented technology that filters CO2 from ambient air.
