“…This method was shown to provide environmental benefits even if the electrical grid's carbon intensity level was 0.2 kg/kWh el . Cost and performance analysis of a hybrid heat pump plus PEM cogeneration system was recently reported [24], where the authors concluded economic and energy benefits of deploying a heat pump in conjunction with a fuel cell. A hybrid PEM-absorption chiller-based cogeneration system was modeled and analyzed for residential buildings where 30% energy savings were reported [25].…”

Electrical and thermal loads of residential buildings present a unique opportunity for onsite power generation, and concomitant thermal energy generation, storage, and utilization, to decrease primary energy consumption and carbon dioxide intensity. This approach also improves resiliency and ability to address peak load burden effectively. Demand response programs and grid-interactive buildings are also essential to meet the energy needs of the 21st century while addressing climate impact. Given the significance of the scale of building energy consumption, this study investigates how cogeneration systems influence the primary energy consumption and carbon footprint in residential buildings. The impact of onsite power generation capacity, its electrical and thermal efficiency, and its cost, on total primary energy consumption, equivalent carbon dioxide emissions, operating expenditure, and, most importantly, thermal and electrical energy balance, is presented. The conditions at which a cogeneration approach loses its advantage as an energy efficient residential resource are identified as a function of electrical grid’s carbon footprint and primary energy efficiency. Compared to a heat pump heating system with a coefficient of performance (COP) of three, a 0.5 kW cogeneration system with 40% electrical efficiency is shown to lose its environmental benefit if the electrical grid’s carbon dioxide intensity falls below 0.4 kg CO2 per kWh electricity.

“…For example, the combined heat and power (CHP) method of cogeneration is mainly used to recover the waste heat of PEM fuel cell system. Fei Yang et al 10 proposed a miniature cogeneration system that combines PEMFC and heat pump to meet the heat and power needs of residential areas at the same time. Jaouher Romdhane et al 11 designed and studied a new miniature cogeneration system based on proton exchange fuel cell and single‐effect absorber, and used the established mathematical model to predict the energy‐saving effect of MCCHP unit for the whole year.…”

The research of hydrogen fuel cell waste heat recovery is a new field of fuel cell thermal management, which helps to improve the overall fuel utilization. At present, the research on the waste heat utilization of fuel cell vehicles is less, and it is more based on the traditional vehicle waste heat management ideas without systematic summary of the factors affecting the system performance. This study takes the waste heat reuse system of fuel cell vehicle as the research object, and established the waste heat exchange rate model and energy consumption model of the waste heat reuse system. Through the study of relevant parameter variables, the effects of parameters on system energy consumption and waste heat exchange rate at low temperature were obtained. The matching design of waste heat reuse system of 60 kW fuel cell vehicle was carried out, and the simulation analysis and experimental verification were done. The results showed that when the ambient temperature is −3 C and −6 C, the waste heat exchange rate of the new matching scheme is 16.2% and 16.3% higher than that of the original scheme, respectively. Also, the total energy consumption of the system is reduced by 62.02% and 60.62%, respectively.
