This research presents a combined heat an‎d power (CCHP) system consisting of photovoltaic-thermal (PVT) panels, alkaline fuel cell (AFC), alkaline electrolyzer (AWE), lithium-ion battery, adsorption chiller, an‎d backup compression cycle. The importance of developing such a system lies in reducing environmental pollution caused by heavy reliance on the fossil fuel-based power grid while utilizing clean resources such as solar energy an‎d hydrogen. Solar energy is used by PVT to simultaneously produce electricity an‎d heat, AFC an‎d AWE enable hydrogen production an‎d recycling, an‎d their waste heat is used to heat the building an‎d provide stable energy supply to the adsorption chiller. The compression cycle also plays a supporting role during peak loads. The physical model of the system is developed in detail in MATLAB/Simulink, an‎d the battery is transiently coupled into the system; an approach that has been less investigated in previous studies. The optimal configuration consisted of 600 m² of solar panels, a 50 kW fuel cell, a 30 kW electrolyzer, an‎d a 75 kWh battery. The results showed that the energy efficiency reached an‎d stabilized at 52%, an‎d the payback period was 7 years compared to the traditional system. Also, the transient coupling of the battery reduced the DC bus voltage fluctuations from ±7% to ±2% an‎d reduced the cycling of the fuel cell by 18%. These results indicate that the proposed system can be a sustainable an‎d economical option for low-carbon an‎d near-zero energy buildings by reducing grid emissions an‎d replacing clean energy.
