Honduras relies on fossil fuels and reservoir hydroelectric power plants to maintain the stability of the national electrical network. Due to the intermittency of renewable resources, solar and wind power plants cannot provide stability to the national electrical network. Renewable plants in the country that use variable renewable resources such as wind and solar have energy shedding controlled by the National Dispatch Center of Honduras to maintain a safe electrical system. Energy shedding can be defined as non-generated energy as a result of power limitations in renewable plants. This energy shedding can be used for green hydrogen production, which can displace fossil fuel technologies, bring stability to the national electrical network, and contribute to the decarbonization process of the country. In this research, sixteen green hydrogen Power-to-Power plants were sized using cumulative energy generation curves built with energy shedding data held by the National Dispatch Center of Honduras. A cost-benefit analysis was used as a decision criterion for the sizing of the hydrogen plants. The annual green hydrogen and energy production by electrolyzers and fuel cells, and the potential for carbon dioxide emission mitigation was estimated. The energy return on investment of each plant was calculated to analyze the harnessed energy in the hydrogen system.Page layout
Introducción: Hay pocas consideraciones en los beneficios indirectos que proporciona la instalación de sistemas fotovoltaicos. El objetivo del estudio fue analizar la influencia de módulos solares fotovoltaicos (FV) instalados sobre techo en la carga térmica de un edificio industrial en Choloma, Honduras. Métodos: El estudio se realizó mediante la instalación y verificación de sensores de temperatura en las caras exterior e interior del techo de área de descarga del edificio antes y después de la instalación de un sistema fotovoltaico. La información registrada por los sensores se utilizó en un modelo termodinámico para calcular la transferencia y ganancia de calor. Resultados: La temperatura de techo exterior presentó una reducción promedio de 9.29 °C después de la instalación de módulos FV. Adicionalmente, la temperatura máxima de techo exterior disminuyó 14.6 °C después de la instalación del sistema. Por otra parte, el techo interior no presentó cambios significativos. El análisis termodinámico mostró que antes de la instalación de módulos FV, la ganancia de calor en los días elegidos en promedio fue de 18.16 Wh/m2 y después de la instalación obtuvo un promedio de 2.94 Wh/m2. Conclusión: Se obtuvo una reducción del 83.8% en la ganancia de calor total a través del techo del edificio.
