Is Hydrogen the Fuel of the Future?

Global warming and melting of the ice on both poles of the Earth is caused by the greenhouse effect which is the result of CO₂ production. This gas is considered as the main gas causing the greenhouse effect, although not the only one. To reduce the total amount of CO2 emitted to the atmosphere, mankind looks for an alternative fuel with no carbon present in its molekules. Hydrogen is such a fuel although emissions are produced also during the fuel production process. To compare hydrogen fuel with fossil fuels, more aspects have to be considered.
