For anyone concerned about climate change, fostering the energy transition from fossil-based to low- or zero-carbon energy sources is a must. In this context, this work provides a brief overview of the clean energy transition in Peru, accounting for a green hydrogen perspective. Accordingly, after the corresponding introduction to the subject, the current situation of renewable energies in Peru is highlighted, along with their historical evolution during the last two decades or so, and the prospects for these more environmentally friendly energy sources in the following years. Next, the potential for renewable energy production in Peru is discussed, with especial emphasis on hydropower, wind, solar, and biomass. Finally, green hydrogen and its potential to contribute to the energy transition in Peru is addressed. A particular emphasis is put in this case on the production of green hydrogen and its applications in Peru and worldwide. From the discussions carried out in this work, it is concluded that, although Peru has a large potential to become a green hydrogen producing and exporting country, there is still a long way to go before Peru can achieve the desired carbon neutrality in the coming decades.

A comprehensive analysis of electrolytic hydrogen production systems based on solar radiation is carried in this work. In the referred analysis, directly coupled photovoltaic-electrolyzer hydrogen production systems were studied. Specifically, the studied systems were split into three subsystems, (i) photovoltaic (PV) power production, (ii) electrolyzer based hydrogen production, and (iii) hydrogen storage in tanks, each of them having its own model considerations and restrictions. Detailed mathematical models for the referred subsystems, including different photovoltaic and electrolyzer related technologies, have been developed and utilized in the analyses performed here. In particular, employing the aforementioned mathematical models, a modeling and simulation platform has been developed. Once developed, such platform has been used to parametrically study the behavior of entire hydrogen production systems, accounting for key variables such as solar irradiance, photovoltaic modules and electrolyzer cells temperature, and hydrogen production rate. Several plant designs options have been firstly determined and from the obtained results a specific one has been selected to further assessments. The particular system studied here is currently in the design phase so the outcomes from this work will be used in future for not only properly sizing it but also building and testing it. It is expected that the implementation of large-scale green hydrogen production plants will reduce the impact of energy production systems on both health and environment.
