Title : Hybrid heating system integrating HT-PEMFC, water heat pump, and steam reforming of biogas for residential applications
Abstract:
This study will investigate a hybrid heating system for residential applications, integrating advanced technologies including steam reforming of biogas (SRB), high-temperature proton exchange membrane fuel cells (HT-PEMFC), a water heat pump (WHP), and thermal storage. Biogas will serve as a feedstock for the SRB unit to produce pure hydrogen gas, subsequently fueling the HT-PEMFC for simultaneous power and heat generation. The waste heat generated by the fuel cell will be utilized effectively by heating the thermal storage tank and pre-heating the inlet of the WHP evaporator, thereby improving the WHP’s Coefficient of Performance (COP). The electricity produced by the HT-PEMFC will power the entire system, making it self-sufficient and optimizing energy usage.
Different scenarios will be evaluated to thoroughly assess system performance under various operational conditions, providing a comprehensive efficiency analysis. Additionally, results will be benchmarked against existing hybrid heating systems that utilize biomass burners integrated with WHP technology. This comparative analysis will highlight the key advantages and identify potential areas of improvement in the proposed hybrid heating configuration.
