Hydrogen technology started many years ago but because of a certain accident that involved hydrogen in the 1970s, a lot of people were discouraged to try it out. Because of the accident, scientists and researchers spent a great deal of their time developing new ideas. At present, hydrogen fuel cell technology is well-accepted in different countries like Canada, Europe, and United States. The use of hydrogen technology is somehow restricted because of certain problems. There are still other things to consider. For instance, gas has been used for many decades now. Oil companies will surely try to maintain their place in the market. They will not let such a competition to arise.
