As the following question was not addressed I though I might lend a helping hand here.
--- Isn't the energy needed to separate the molecules the same as the energy gained when you let them react? ---
If this would be the case any catalyst manufacturer would never have gotten into business in the first place!
This is a common mix-up as it is true that if the path of separation and unification are the same that energy used respectively emitted are the same.
If a catalyst is introduced this is not applicable and as we all know catalysts work very well and we are all happy about their performance in each car.
This in itself is already proof enough that the phrasing, particularly of the English version, of the second law of thermodynamics is flawed. If it is transposed to commonly understandable English it actually states that: "given an unlimited source of low energy you can't get it out."
Looking at it this way it's obvious that can't be true as there are numerous mechanical machines doing exactly that.
Where such applications still get severely stuck is the same problem solar energy faces. Solar needs large collector area and environmental energy devices need large heat exchange surface. Both of which are expensive and with that the levelized energy cost go through the roof. Good work in the field is being done worldwide but as we can see here it is a battle with two fronts and they are hard to win.
... all the best
