MIT scientists discover how to convert CO2 into powder that can be stored for decades
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.
