20% of Car CO2 Could Be Captured

Producing carbon dioxide is an unavoidable part of burning fuel in cars. The problem with this of course is that carbon dioxide is a greenhouse gas. And the more cars there are on the road, the more sources of this greenhouse gas there are. The concept of carbon dioxide capturing has been theorized for a while now, but researchers at Saudi Aramco and ExxonMobil are starting to take it seriously, writes Antony Ingram of GreenCarReports. Using 20 percent carbon dioxide capture on a 20 mpg vehicle could give it CO2 emissions equivalent to an existing 37 mpg vehicle. "When you fill up your car, the CO2 would be extracted as the fuel goes in," Ingram explains. "The trouble then is deciding how to manage such a system -- and potentially, how much that might cut from the cost of the fill-up, since CO2 is a trade-able resource used in beverage processing and industry."
