FUTURE'S FUEL BE SOLAR HYDROGEN

Abstract

Earth runs out of fossil fuels within the foreseeable future. The production of nuclear energy is risky. Hydrogen produced by solar energy through mainly electrolysis is an attractive - maybe the best - alternative to fossil fuels. Solar hydrogen is abundant and everlasting energy carrier. As a fuel it is clean and has the highest caloricity. In spite of high price of solar hydrogen nowadays it is considered to become economically competitive fuel in the next century.
