Researchers at the Massachusetts Institute of Technology exposed CO2 to catalysts and then electrolysis that turns the gas into a powder called sodium formate, which can be safely stored for decades. The breakthrough follows an almost century-long effort to turn CO2 into a cheap, clean fuel. Researchers have previously turned CO2 into fuels that required too much energy to make or were difficult to store long-term.
