Abstract: Methods and structures to release heat energy from hydrogen atoms by stimulating their electrons to relax to a quantized potential energy level below that of the ground state via an electrochemical reactant(s) of redox energy resonant with the energy hole which stimulates this transition. Methods and structures to conform the electronic energy of the hydrogen atoms and the redox energy of the eletrochemical reactant(s) to enhance the hydrogen electronic transition rate where the source of hydrogen atoms is aqueous electrolyic production on the surface of a cathode.
