Energy and cost analyses of a hybrid renewable microgeneration system serving multiple residential and small office buildings

摘要: Abstract This study investigates the energy and cost performance of hybrid renewable ground source heat pump (GSHP) natural gas fueled fuel cell (FC) microgeneration systems serving multiple residential small office buildings in Ottawa (Canada) Incheon (South Korea). The is performed by simulations TRNSYS environment. system compared to a GSHP only system. In addition, impact FC capacities, price electricity on system's examined. analysis results show that GSHP–FC have less primary consumption both geographic locations. However, whether could achieve operational saving strongly dependent local prices also building heating, cooling electrical loads their patterns. yield savings at locations where (or other input FC) much lower than price, such as Ottawa. At with exceptionally high ratio, Korea, no be attained indicate that, Ottawa, extra capital investment incurred possible returned within its lifespan, especially current trend continuous reductions equipment installation resulting from economy scale market expansion. Nevertheless, systems' capability generate thermal point use generally considered more attractive for inclusion “smart” networks, new remote community applications.
