Experimental Canadian factory began processing CO2 into fuel for cars
To make the surrounding air cleaner, it is necessary to reduce the content of CO 2 in it by reducing harmful emissions. But this, alas, is not enough. According to environmentalists, the accumulated CO 2 should be forcibly removed from the atmosphere and processed. Until recently, its “mining” technologies were considered too expensive to be used on an industrial scale.
Encouraging news came from Canada, where the Carbon Energy (CE) plant, which uses the economical direct air capture technology (DAC), operates successfully for the last three years.
According to CE representatives, DAC technology is not new. Last year, the Swiss company Climeworks installed a CO 2 capture facility near the pipe of an enterprise near Zurich. A few months later, the company, together with specialists from the geothermal power plant, developed a technology for converting CO 2 to stone. However, from purified carbon it is also possible to produce methanol, carbon nanofibres 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 reduce these figures to 95-230 dollars.
The pilot plant consists of an industrial cooling tower specially adapted for extracting CO 2from the air and converting it from a gaseous state to a solid state, followed by transformation into an already purified gas. To capture CO 2 , a liquid solution is used that turns it into a carbonate, which is given a cake shape. After heating in a special furnace, purified gas is extracted from them.
It can become the basis of synthetic fuels, for which CE was developed a technology called Air To Fuels, which turns purified CO 2 into liquid hydrocarbon fuel, which is quite suitable for modern cars.
