|b Hydrogen is very important in the last time as it is considered a safe haven for developing countries, especially Egypt. Where Egypt depends on the needs of energy to oil, which is the largest source of energy followed by natural gas and the third source of hydropower, the fourth energy, the sun and wind, and these traditional sources in addition to renewable sources are not enough energy needs, and thus hydrogen is the fuel of the future where it was found that the combustion of grams of Hydrogen generates more energy than generated from the same conventional fuel. It is also distinguished from traditional sources of energy as a clean and safe source of energy. It is also distinguished from renewable sources as the most abundant element in nature and less expensive than renewable energy technologies. Of where the water can be extracted from algae. Thereby making hydro-gen particularly suitable for use in fuel cells as a source of electrical power. Fuel cells interact with hydrogen and oxygen to generate the electricity needed to run the engine. This reaction produces potable water and does not react to harmful emissions that are polluting the environment. Hydrogen engines are almost as efficient as conventional motors, with a reduction in cost. Hydrogen engines consume approximately 2.9 liters of fuel per 100 kilometers. The operating range of these engines is about 400 kilometers and the maximum power is 115 horsepower. Hydrogen fuel cells have several advantages as their fuel comes from external sources and therefore the energy does not carry out like the conventional battery.
