Abstract
Green hydrogen produced from solar energy is emerging as a technical option to support the transition toward a sustainable energy model. This article presents an updated literature review on the most relevant advances in solar-powered electrolysis technologies, focusing on efficiency, costs, and commercial feasibility. The main types of electrolyzers are examined, along with their operating conditions and limitations. The analysis includes key economic factors that influence the competitiveness of green hydrogen, particularly the levelized cost of hydrogen (LCOH), which is affected by storage infrastructure and electricity prices. Although technical and financial challenges remain, solar-based hydrogen production is presented as a concrete option to diversify energy portfolios and reduce emissions in the energy sector.
