The apocalyptic scenario of mankind’s future should mobilize the international community to take global measures to reduce atmospheric pollution, and to produce clean and useful energy especially electrical energy from non-conventional sources : sun, wind, sea, waves, tide, and geothermal energy.
The exhaustion of available conventional fuels (natural gas, coal, oil) is the near future. The time limit for this process is estimated to be a few decades for natural gas and oil, and about two centuries for coal. It is evident that, as these fuel reserves are depleted over time, their cost will continuously increase.
Hydrogen is a gas with physical and chemical properties recommended for use as fuel for thermodynamic engines and plants; it has many advantages over conventional fuels such as coal and hydrocarbons. A very important ecological advantage is that Hydrogen combustion does not produce greenhouse gas (CO2) or SO2 noxious gases.
