Extrapolation of world energy consumption from 1990 to 2008 will result in the complete exhaustion of world reserves of oil, natural gas, uranium and coal until 2040, 2046, 2048 and 2054, respectively. For the survival of all people in the whole world, intermittent and fluctuating electricity generated from renewable energy should be supplied in the form of usable fuel to all people in the whole world. We are proposing global carbon dioxide recycling for the use of renewable energy in the form of methane via electrolytic hydrogen generation using carbon dioxide as the feedstock. We created energy-saving cathodes for hydrogen production, anodes for oxygen evolution without chlorine formation in seawater electrolysis and catalysts for methanation of carbon dioxide and built the pilot plants of industrial scale. Recent advance in materials is described. The industrial application is in progress.
