The paradigm of boosting hydrogen production performance through water molecule destabilization using electromagnetic wave aids has emerged. The new paradigm opens the possibility of minimizing the use of noble metals or specially designed nanostructure catalysts, which promise more efficient green hydrogen production and affordable hydrogen through water electrolysis. However, there is currently no available guide to choosing the fittest electromagnetic wave within a certain scope. This study provides a framework for the selection of electromagnetic wave aids. This study reports the first integration of the analytical hierarchy process (AHP) with molecular mechanics for the determination of the water electrolysis booster. The criteria for the selection are the electromagnetic waves that enable water vibration in symmetric mode, asymmetric mode, and each combination. The electrolysis test results consistent with the AHP selections favor the high hydrogen evolution rate (HER) process. The best electromagnetic wave aids are the combination of all vibration modes, asymmetric-symmetric, and asymmetric mode, with HER 0.4127639 mol. L-1, 0.385477854 mol. L-1, and 0.3467812 mol. L-1, respectively. The order is aligned with the AHP consistency ratio of each selection. The AHP selection demonstrates the superiority of asymmetric and symmetric vibration modes in enhancing green hydrogen production. © 2024 Elsevier Ltd
