Hydrogen is extracted from a water molecule and used as a fuel to generate electricty and heat. This is the exact application discussed on here a few weeks ago and discounted as not being viable. It's still in its infancy, but it is promising. Discuss!

Do I really have to explain why this is not an energy source.

Let me explain

The first step is to get the Hydrogen

2H2O + A LOT OF ENERGY -----> 202 + H2

Now you use the hydrogen as fuel.

2O2 + H2 -----> 2H2O + Less energy than you put into it in the first place.

The fact that you can get hydrogen from water and then use that hydrogen as a fuel is not new, people have know you can seperate hydrogen and oxygen for well over a century (probalby more, I dont' know the exact date).

The problem is that if you use more energy than you get from using it as a fuel.

Will it reduce emmisions? NO, because you end up using more energy, and that electricity you have to use to procuce the hydrogen has to come from somewhere, and in this world, that is prodominently from fossil fuels.
You're better off to just use a battery.

Adding unnecessary complexity to a process adds inefficiency.
