The effects of light energy fields on the molecular and electrochemical dynamics during water electrolysis

Hydrogen will be an integral component for the transition to sustainable energy generation and storage due to its favourable characteristics and versatility in its application. This research provides a greater understanding of the potential light energy has to increase water electrolysis efficiency by examining the effects that light energy fields have on the molecular and electrochemical dynamics during electrolysis. The results indicate that light energy increased efficiency by ∼10%, while enhancing the molecular dynamics, regardless of application. The application of a line laser generated the highest gains in efficiency, with a maximum of ∼15%. Furthermore, the application of a line laser with a linear magnetic field resulted in a synergistic effect which generated higher increases in molecular dynamics as well as an ∼18% increase in efficiency and a ∼58% increase in hydrogen gas production. As such, the application of light energy fields presents a promising method for enhancing water's molecular dynamics and electrolysis efficiency. • Increasing the efficiency of hydrogen production with light energy fields. • Light energy fields increase the molecular energy of H 2 O during electrolysis. • Increases in water's molecular energy enhances electrolysis. • Enhanced load adaptability with light energy fields.
