Resumen

At a global level, energy production is predominantly based on the use of conventional resources such as oil, coal, and gasoline; this dependence has led to adverse effects such as climate change and detrimental impacts on human health; consequently, green hydrogen emerges as a renewable energy source. This work develops and analyses the parameters of a portable hybrid system to produce green hydrogen on a small scale in a more efficient way, allowing it to be placed in rural areas to be used as an ecological fuel source. The hybrid system is divided into two stages; for energy production, a microhydraulic system was developed based on an Archimedes screw turbine, which is made up of a mechanical and electrical design, where the electricity produced is stored in a continuous energy source, which supplies the electric current to the electrodes in the alkaline electrolysis process; where a reaction occurs in the water resource to produce green hydrogen and oxygen. It was demonstrated that the turbine, when presenting a greater wetted area and slope of fall, produces a higher electrical potential, while in the electrolysis process to produce green hydrogen and oxygen, it was determined that the appropriate electrolyte to use is potassium hydroxide at 20% because it has greater electrical conductivity unlike sodium chloride and sodium hydroxide; evidencing the most efficient parameters to implement the hybrid system in rural areas to replace the conventional fuel that is used in cooking food.
