One of the main problem of modern science, that bothers all countries, is the problem of energy, that is finding new sources of energy: hydrogen, ethanol, biofuels, natural gas, electricity, energy, wind, solar radiation.
Nowadays humanity faces energy crisis. The search for alternative energy sources is associated with both the constant rise in prices for fossil fuels, and because of environmental concerns. And such energy sources as coal, oil, gas are exhausted rapidly, every year the mining of these minerals is continually increasing and they will be enough only for 30-40 years. That is why scientists have started to now investigate the possible options for their replacement.
The most promising, perhaps, of all types of energy sources of the future is hydrogen, and its uniqueness as an energy source is obvious, also it can solve many environmental problems.
