I think you answered your own question.
Hydrogen atoms will bond then detach when ADP is formed. It has to do with the valence electrons and the bonds created.
The two outermost phosphates in ATP are held to the rest of the molecule by high-energy phosphoanhydride bonds and are readily transferred. Water can be added to ATP to form ADP and inorganic phosphate (Pi). This hydrolysis of the terminal phosphate of ATP yields between 11 and 13 kcal/mole of usable energy, depending on the intracellular conditions. The large negative delta G of this reaction arises from a number of factors. Release of the terminal phosphate group removes an unfavorable repulsion between adjacent negative charges; in addition, the inorganic phosphate ion (Pi) released is stabilized by resonance and by favorable hydrogen-bond formation with water. The formation of ATP from ADP and Pi reverses the hydrolysis reaction, and it requires a coupling of this energetically unfavorable reaction to an even more favorable one.

In Oxidation-reduction reactions one atom or molecule loses one or more electrons while another atom or molecule gains those electrons . The compound that loses electrons becomes oxidized; the compound that gaines those electrons becomes reduced. It is usually easier to lose a whole hydrogen (H) atom - a proton and an electron.
In ATP Synthesis ,Oxygen does not work without Hydrogen . When ATP is formed, the two Hydrogen atoms combine with Oxygen to produce a byproduct, pure water, also critical to life. If there is an ample supply of electrons in the body, production of ATP increases, adding to the energy level without increased toxicity. So as its easy for Hydrogen to release the electron its necessary in the process.So energy and water are produced during the same process.

ATP - Adenosine Triphosphate.
Hydrogen atoms are important in a cycle converting ADP[Adenosine Diphosphate into ATP]
The hydrogen atoms can attach itself to a Phosphate group to be attach to ADP to form ATP.
And then later detaches itself.

well according to me H atoms do not have a funtion in synthesization of ATP from ADP in Light Reaction. The fact si that, the released electrons in photolysis of water are used to make ATP. Hyrogen ions reduce NADP to NADPH
