Extensive development of human society leads at an increase for energy demands leading at increase of fossil fuels consumption. Rapid climate changement during last decades make necessarily the development of new energy production systems. In 1874 Jules Verne wrote in his book The Mysterious Island:” …… water will one day be employed as a fuel, that hydrogen and oxygen that constitute it, used singly or together, will furnish an inexhaustible source of heat and light, of an intensity of which coal is not capable. Someday the coal rooms of steamers and the tenders of locomotives will, instead of coal, be stored with these two condensed gases, which will burn in the furnaces with enormous caloric power…I believe, that when the deposits of coal are exhausted, we shall heat and warm ourselves with water… Water will be the coal of the future…. “. Student will be able to understand the hydrogen economy and the future hydrogen usage. Topic covered include introduction in hydrogen economy (production and usage) and will let participants to understand the future of hydrogen usage as energy vector.
