Hydrogen Fuel Cells – Number One Environment Friendly Fuel

Hydrogen fuel cells help the environment a great deal, and its’ development makes it a good alternative fuel. Even though hydrogen fuel cell technology helps to save the environment by preventing global warming, we need to investigate all the facts surrounding it and understand how it all works.

The good thing that has come out of developing hydrogen fuel cells is that it is the cleanest burning fuel to come about. Hydrogen is used as a gas when it has been taken out of water and put into fuel cells, so that it can then be used to power a vehicle. Water vapour is the only emission from a vehicle powered by fuel cell. It is like a giant humidifier fit for the world. However, there are downsides to related to hydrogen fuel cells and the environment.

If the system of producing hydrogen, storing and also transporting is entirely efficient, the principles of it suggest that there would be no gas emissions.

Researchers show that that this kind of system proves very expensive, and that in fact about 10-20% of hydrogen is likely to escape into the earth’s atmosphere. If, for example, hydrogen fuel cells were used in place of gas-based and oil combustion technologies, the total of hydrogen deposits into the air would double or triple at the surface of the Earth.

Once hydrogen hits the stratosphere, some researchers say that it would oxidise, cooling the stratosphere, and so cloud formations would increase. In the North and South poles, the polar vortex would take longer to break up, so increasing the size of the holes already in the ozone layer and make them long-lasting. An estimated 5-8% rise in depleted ozone due to this excess hydrogen would occur at the North Pole and at the South Pole about 3-7%.

All this excess of ozone depletion cannot be measured exactly, as there is no known figure of unknown quantities which it is reliant on. As the amount of future hydrogen emissions cannot be measured, it is not understood how much hydrogen soil can absorb from the atmosphere. Researches that it is possible for this process to compensate for any of the new emissions dispersed into the atmosphere.

It is true to say that hydrogen fuel cells can actually be safer for the environment long term when used as a fuel alternative. As water vapour is the only emission resulting from using hydrogen fuel cells, this is a much better advantage and outweighs the use of gas powered cars which burn and produce emit toxic waste into the air.

All in all hydrogen fuel cells is more promising than other available alternative fuels, and much better all round for the environment. The advantages of hydrogen as alternative exceed the disadvantages and looks to be the best way forward.
