Abstract
Since the Industrial Revolution, the heavy reliance on the limited fossil energy has emitted huge number of CO2 into the air and led to a severely global warming. We propose a new green technology to moderate greenhouse gas CO2 emission and transform it into low-carbon renewable energy in this paper. Through this manner, electricity is transformed into chemical energy. CO2 and H2O is directly simultaneous electrolysis under constant 0.25 A with 30 cm2 nickel anode and 30 cm2 iron cathode in a 600 °C alkali carbonate with LiOH electrolyte in mole ratio of nH:nC = 0.15:1, achieving the storage of electricity to chemical energy. This electrolysis provides a gaseous product comprising 45.9% methane, 53.1% H2, 0.92% CO and trace amounts of longer (than methane) hydrocarbons. Simultaneously, the current efficiency is still â¼51% for 60 min.
