>Cool Solutions - My own focus - Hydrogen Cars<

Hydrogen is an energy carrier, and its energy efficient use involves the use of fuel cells and electric motor. Hydrogen reacts with oxygen inside the fuel cells. Electricity is produced, and thus the motor is powered. Hydrogen is produced from a renewable energy source. So cars powered with hydrogen are eco-friendly since they reduce the greenhouse gas emission.

Fuel cell vehicles are expected to achieve energy efficiency of 40 to 45%, while the internal combustion engine of cars uses only 16% of the energy in gasoline. Another interesting feature of hydrogen cars is that they operate with electric motors which have very few moving parts. This will greatly reduce the car vibrations and noise. There will be no need to do routine maintenance like oil changes and spark plug replacement. Fuel cells in hydrogen cars are better than the battery, because they do not need any charging time, allow a wide range of speeds, and operate as long as fuel is supplied.

Petrol cars produce air pollutants like carbon monoxide, and nitrogen oxides, and greenhouse gas emissions like carbon dioxide and nitrous oxide. Fuel cell powered cars will not just reduce air pollution, but also noise pollution and groundwater contamination. This will improve public health and safety from reduced exposure to the dangerous emissions.

A fuel cell powered car is an important technology in the fight against global warming which is resulted because about 25% of all human-generated greenhouse gases come from transportation. This technology is still in the experimental phase. I believe the UAE government needs to establish research centers that will work hand in hand with the international research centers to speed up the replacement of the petrol cars with the eco-friendly hydrogen cars.
