Efficient Generation of H2 by Splitting Water with an Isothermal …

Webbto split water into hydrogen and oxygen; ΔG as a useful work and TSΔ as a thermal energy. The Δ−GT diagram for the water splitting reaction is shown in Figure 2. The water decomposition reaction has a large positive free energy change and a small positive entropy change, as can be seen in Figure 2. Thus, the equilibrium for the WebbCalculation for 1 kg of water (55.55 moles): Energy for electrolysis: 237.13 kJ * 55.55 = 13.173 MJ Energy released by Hydrogen combustion: 0.002 * 55.55 * 141.86 MJ = 15.76 MJ These calculations are not taking in account efficiency and energy loses, they are purely theoretical. WebbTheoretical modelling shows that two-photon water splitting can be used to achieve a maximum solar-to-hydrogen efficiency of 18.8%, which could be increased further to 28.6% through photochemical instead of thermal H 2 release. It is therefore possible to exceed the maximum efficiency of dual absorber systems while only requiring a single catalyst. raymond district
