Abstract

A key strategy for optimizing the utilization of clean energy sources involves integrating energy vectors to effectively
manage surplus power generated from renewable sources. This study specifically delves into the assessment of a hydrogen (H2) generation project utilizing energy generated by the Hidroabanico power plant. Over a span of 13 years, the average monthly energy production was meticulously scrutinized, with a determination that 20% of this energy would be allocated for H2 production. The operational framework of the prototype plant, which relies on Proton Exchange Membrane (PEM) electrolyser technology, is comprehensively elucidated. This system boasts an annual energy capacity capable of reaching 62,439 MWh (20% of total production), culminating in the production of 1,123 Tn of H2. However, it is noteworthy that this quantity remains relatively limited compared to analyses conducted utilizing
alternative technologies.

Key words: Hydrogen fuel, electrolizer, PEM.
