“…The phenomenon of increased hydrogen release in the presence of laser radiation with a wavelength of 532 nm, i.e. of green laser radiation, can be explained through the concept of electrical susceptibility or through the dielectric constant of water (Bidin et al, 2014). Both physical quantities relate to the polarization of water by an electric field.…”

The dominant problem that needs to be solved today is the issue of energy sources and how to use them, which must be ecological and sustainable -in a word, green. As the best candidate for a global solution to this problem, hydrogen produced electrolytically stood out as a green fuel with no carbon footprint. However, for a hydrogen-based economy to have a realistic and sustainable perspective in the future, it largely depends on its efficient and economically viable production that would meet the market's needs. Special attention in this paper is devoted to the influence of laser radiation on the possibility of improving the process of alkaline electrolysis for obtaining hydrogen, as well as on increasing the amount of separated hydrogen when the electrolytic cell is directly irradiated with a laser beam during the electrolysis process itself. After the experiments, it was determined that the application of direct irradiation of the electrolyte with a green laser at 532 nm wavelength significantly increases the amount of hydrogen produced and reduces the voltage of the electrolytic process, which is directly related to the increase in the energy efficiency of the overall hydrogen production process.

“…Still, it requires more innovations to become dominant. In recent years, photolytic processes that use the energy of laser radiation to destroy water molecules have been studied and improved greatly (Perret et al, 2007;Bidin et al, 2014).…”

“…The process was referred to as hydrogen production by infrared (HyPIR) electrolysis and is based on concepts reported in the literature [3,4,5]. Other electrolysis techniques include hydrogen production by green laser irradiation [6], hydrogen production by PEM electrolysis [7], hydrogen production by electrolysis powered by renewable energy [8], low temperature water electrolysis [9], alkaline water electrolysis in the presence of a magnetic field [10], and a solar-to hydrogen device based on earth-abundant…”

Previous laboratory work using a 0.12 M Epsom salt solution showed that HyPIR Electrolysis, or Hydrogen Production by Infrared Electrolysis, can increase the rate of hydrogen production from a solution of Epsom salt dissolved in water by irradiating the electrolyte with an optimum wavelength of light. This article presents data for a 0.25 M Epsom salt solution. A comparison of the data for different molarities shows that an increase in molarity of the electrolytic system decreases the rate of hydrogen production.
