It's funny how we still seem to continue to want to rely upon the fossil fuels. Even though it has been known for decades that this type of reliance on this fuel was only going to lead us where we are today. Paying prices that are nearly unheard of and continuing to pollute the air that every living creature on this earth needs to have in order to survive. Yet, the number one source of fuel still remains fossil fuels.
However, hydrogen is probably one of the better alternatives that we have available and can be created from both biomass and methane gas and there is an abundance of this resource to use. So why the fuss over hydrogen technology? It's not like it is truly something brand new and can't be trusted. Many people make think that the use of hydrogen is some new idea that someone just came up with, but that is far from the truth. The very first time that hydrogen was used as a fuel was in 1807. It was used in the Rivaz car that contained the very first internal combustion engine.
This very first internal combustion engine took hydrogen that was stored and compressed and put it into a balloon that was triggered by an electrical cell ignition. Amazing to think that even before Henry Ford developed his first Model T, there was already an engine idea far better than his just sitting there waiting for us to take advantage of. And here we are today, still not utilizing it completely.
The way that hydrogen works is quite simple. When hydrogen gas is stored in a tank, it then can be ignited while in the presence of oxygen which is, right there in our atmosphere. When these atoms combine they will release a lot of heat energy which n turn simply produces water vapor as the exhaust bi-product. This is all done through an electric fuel cell that helps pass the oxygen to the cathode. This then splits the hydrogen atoms into protons and electrons. All of this produces an electrical current which then in the end produces the water as the exhaust.
The advantages of using hydrogen are numerous but the main ones are that unlike fossil fuels that take millions of years to produce, hydrogen is a renewable way to acquire energy. It can be found in waste materials that normally can pollute but can be put to better use by breaking them down to get the hydrogen gas from them. Comparing the two when it comes to pollution, we all know what the fossil fuels produce and how destructive they have been and then there is the water vapor from the hydrogen. It should be a no brainer, yet they continue to claim it will be at least 40 years before any major changes can be done.
The main disadvantage of hydrogen over fossil fuels is that it takes more hydrogen to fuel a vehicle than fossil fuels. In other words a vehicle will run out of energy quicker than if they were using a more traditional form of energy. The method of making the hydrogen fuel is not totally pollution free. However, it is doubtful that it's production has nearly as much negative affect on the earth as all of the exhaust coming from the millions of cars all over the world.
