Tóm tắt

Standalone solar-hydrogen systems, integrating components like PV panels, fuel cells, and hydrogen storage, offer a promising solution for off-grid power and heat generation, particularly when enhanced with heat recovery from fuel cells in combined heat and power (CHP) applications. By integrating solar thermal collectors, these systems can overcome the limitations of intermittent solar heating and potentially achieve 100% renewable heat and power supply without auxiliary energy sources. This study proposed a novel mathematical model based on the laws of thermodynamics to investigate the energy and exergy efficiency of a proposed standalone solar hydrogen integrated with solar hot water collector. The impacts of solar radiation on the performance of the main components and whole system are investigated. The results show that the energy efficiency and exergy efficiency of the proposed system is only around 12% and 9% respectively.
