CO2 emissions, which induce global warming, increase with the development of economic activity. It is impossible to ask the CO2 emission decrease based on suppression of the economic activity. Global CO2 recycling can solve this problem. The global CO2 recycling consists of three district: The electricity is generated by solar cells on deserts. At coasts close to the deserts, the electricity transmitted from the deserts is used for H-2 production by seawater electrolysis and H-2 is used for CH4 production by the reaction with CO2. CH4 is liquefied and transported to energy consuming districts where, after CH4 is used as a fuel, CO2 is recovered, liquefied and transported to the coast close to the deserts. Since 90% of city gases in Japan is liquefied natural gas (LNG) that consists mostly of CH4, CH4 produced in the global CO2 recycling on be used immediately as the city gas. A CO2 recycling plant for substantiation of our idea has been built on the roof of our Institute (IMR) in 1996. Rey materials necessary for the global CO2 recycling are the anode and cathode for seawater electrolysis and the catalyst for CO2 conversion. All of them have been tailored by us. Since quantities of CO2 to be converted far exceed an ordinary industrial level, the system must be very simple, the rate of conversion must be very fast and precious metals must not be used for the system. All these requirements are satisfied in the global CO2 recycling. When the global CO2 recycling is conducted in a large scale, the energies and costs required to form liquefied CH4 in the global CO2 recycling are almost the same as those for production of LNG from natural gas wells. The project to examine feasibility of the global CO2 recycling has been planned in Egypt in cooperation of Egyptian and Japanese scientists, engineers and industries.
