Renewable Energy–Driven Green Hydrogen Production: Integration Technologies and Future Prospects

Abstract

The increasing global demand for sustainable and low-carbon energy has highly accelerated research on the hydrogen as an alternative clean fuel. Renewable energy sources undergo electrolyzed water to produce green hydrogen that can be a reasonable hydride alternative to decarbonizing the world energy system. The current research is an experimental study to test how the renewable energy of hydrogen can be produced through the use of solar energy and wind energy produced through the combination of the two technologies. The efficiency of the system, the rate of hydrogen production, and the rate of energy consumption are analysed through the evaluation of a simulated renewable energy electrolysis system driven with electrolyzer of 10 MW. The experiments conducted reveal that approximately 50-55 kWh of electricity is required to transform 1 kg of water into hydrogen via electrolysis of this substance and the findings of the electrolysis process will be based on the efficiency of the system.

The research methodology consists of thermodynamic, electrochemical and system performance studies. The efficiency of the hydrogen production is established based on numerical modelling of hybrid electrolyzer system using the basis of solar-wind. The results point out that renewable energy sources combined with running of the proton exchange membrane electrolysis would enhance flexibility in operations and increase the capacity of the production of hydrogen. The results of the experimental simulation indicated that, based on the current idealized operating conditions a 10 MW of electrolyzer system can be used to assist in production of about 200 kg/h of hydrogen.

According to the findings, the renewable hydrogen systems can reduce carbon emissions by a substantial percentage and can also provide a long-term energy storage. Putting it into large-scale use remains stalled by system efficiency issues, however, by intermittency of renewable energy and infrastructure challenges. As the paper concludes, the availability of the hydrogen economy in the world in the future will be pegged on the support of the technological advances due to contributions by making strides in the field of electrolyzers, integrating with the renewables and storage of energy.
