Reason: "In this house, we obey the laws of thermodynamics!". You will need energy to produce fuels, and you have to put more energy in than the fuels will be able to produce. So, unless you already have an energy source that is cheaper than fossil fuels, this one will not be, either.
Also, I am not a chemist, but chances are that it will take time to make this invention useful, if it is possible as all. I do not think enzymes are as chemically stable as platinum, and hydrogen is quite reactive. Worse, if you pick the obvious stuff (water) as source for your hydrogen, you also end up with oxygen. That, too, is quite reactive.
