New Atlas – Rooftop CO2 capture system pipes greenhouse emissions to a greenhouse

In the case of the plant in Hinwil, the pure CO2 is piped to a greenhouse 400 m (1,312 ft) away, where it’s used to grow vegetables. But Climeworks says the gas could also be used for a variety of industrial applications, like creating other climate-neutral fuels, carbonating beverages, or simply being stashed away underground.

To make it as efficient as possible, the DAC plant is powered by the excess heat from the facility underneath it. In its current form, the system can capture as much as 900 tonnes of CO2 every year, and to demonstrate its effectiveness the Hinwil plant will operate as a pilot project for three years. After that, Climeworks has outlined some pretty ambitious plans.
