Experimental Canadian factory starts converting CO2 into car fuel

To make the air around us cleaner, it is necessary to reduce the CO 2 content in it by reducing harmful emissions. But this, alas, is no longer enough. According to ecologists, the accumulated CO 2 should be forcibly removed from the atmosphere and recycled. Until recently, the technologies for its "extraction" were considered too expensive to be applied on an industrial scale.

Encouraging news came from Canada, where Carbon Energy's (CE) plant has been successfully operating for the past three years, using cost-effective direct air capture (DAC) technology.

DAC technology is not new, according to CE officials. Last year, the Swiss company Climeworks installed a CO 2 capture plant near the chimney of a plant near Zurich. A few months later, the company, together with specialists from a geothermal power plant, developed a technology for converting CO 2 into stone. However, the purified carbon can also be used to produce methanol, carbon nanofibers, and even diesel fuel.

At first, the operation of such installations was quite costly - the cost of a metric ton of material reached $ 500-1000. CE managed to bring these figures down to $ 95-230.

The pilot plant consists of an industrial cooling tower specially adapted for extracting CO 2 from air and converting it from a gaseous state to a solid one with subsequent transformation into an already purified gas. To capture CO 2, a liquid solution is used that converts it into carbonate, which is formed into cakes. After heating in a special oven, purified gas is released from them.

It can become the basis for synthetic fuels, for which CE a technology called Air To Fuels was developed, which converts purified CO 2 into a liquid hydrocarbon fuel, which is quite suitable for modern cars.
