I have heard about the advancement of hydrogen fuel cells as an energy replacement for oil. Does it work?
No, at least it does not right now. The idea of creating a kind of battery that never needs recharging by mixing hydrogen and oxygen in a fuel cell to produce an electric current is certainly not new. Scientists have been working on this capacity since the 1980’s and while we know more now than back then about this type of energy system, the largest companies in the world involved with the research and development of hydrogen fuel cells have scaled back their staffs dramatically and have seen their stock prices crash. This method has a long way to go. There simply is no replacement for the combustible engine and the need for petroleum to be used for its operation.
