Swiss Plant Sucks CO2 Out out of Air to Repackage Sell

According to Gebald, the filters fill up “within a few hours.”Once saturated, the CO2 is isolated at a temperature of about 100 ℃ (212 ℉). That gas can then be sold to folks in commercial agriculture, the food and beverage industries, the energy sector, and the automotive market.Direct Air Capture plant near Zurich (via Climeworks)The plant opened just one day before President Trump pulled the US from the Paris climate agreement, which aims to limit a global temperature rise of 2 ℃ (35.6 ℉).“Highly scalable negative emission technologies are crucial if we are to stay below the two-degree target of the international community,” Gebald said in a statement. “The DAC technology provides distinct advantages to achieve this aim and is perfectly suitable to be combined with underground storage.“We’re working hard to reach the goal of filtering 1 percent of global CO2 emissions by 2025,” he continued, estimating the need for some 250,000 more plants.Climeworks is also eyeing underground storage as a way to deliver negative emissions.last_img read more
