Free Gas Promise of New Sustainable
Power Source at Hand
British engineers at Air Fuel Synthesis have succeeded in using an innova- tive new “air capture” technology to remove carbon dioxide greenhouse emissions from the air and transform them into synthetic gasoline. The two-year experimental project mixes sodium hydroxide with carbon dioxide before electro- lyzing the sodium carbonate that it produces to form pure carbon dioxide. Hydrogen is then produced by also electrolyzing water vapor captured with a dehumidifier. The carbon dioxide and hydrogen then produce methanol, which is passed through a gasoline fuel reactor to create the fuel. The prototype mini- refinery, in Stockton-on-Tees, in Teesside, produced five liters of gas in less than three months. A larger plant might produce more than a ton of gasoline every day, and a refinery-sized operation is envi- sioned within 15 years. The fuel can be used in any regular application and if renew- able energy were used to provide the electricity, the system would be completely carbon neutral. While the technology has the backing of Britain’s Institution of Mechanical Engineers and private philanthro- pists, it has yet to capture the interest of major oil companies.
