Hydrogen energy system based on materials recycle

Abstract

In order to attain the sustainable growth of human beings, the clean energy system should be constructed. The system should not destroy the global environment. However, CO₂ concentration in the atmosphere is increasing and the green house effect is expected. In the paper, the global recycles of carbon and water ware compared quantitatively. The existence of water is 27,000 times larger than that of carbon. The transportation of water is 3,160 times faster than that of carbon. These figures should that the hydrogen from water might be a superior energy carrier, compared to the carbon.
