An international team of researchers developed a method to convert the carbon dioxide emitted from factories into fuel feedstock without cleaning or purifying the gas. Traditionally, carbon capture requires costly, energy-intensive purification steps. A paper published in Science estimates that separating carbon dioxide from coal flue gas and compressing it to 150 bar requires at least 0.11 megawatt-hours per ton, or about 0.4 GJ. The… The post Researchers develop method to convert factory emissions to fuel feedstock without purification appeared first on Research & Development World .
