The background of this research is based on the commercialization trends of the H-2 vehicles and the upcoming legislation on the zero-energy building (ZEB). Regarding these two backgrounds, there is special research interest to investigate the technical feasibility of integrating a H-2 vehicle with an on-site renewable electrical (REe) system in the ZEB. Hereby, a hybrid system consisting of an on-site REe and a H-2 vehicle integrated H-2 system is proposed and set up in the TRNSYS simulation with novel control logics defined by the authors. The essential principle is to drive the electrolyzer with the surplus onsite REe, and to drive the fuel cell to cover the on-site electrical shortage, while the cogenerated heat from the H-2 system will be utilized for domestic heating purposes. The simulation 'results show that with the support of a 14 kW wind turbine, the building will be a nearly ZEB with full annual availability of the H-2 vehicle, whereas with the support of a 178 m(2) PV, the building will be a net ZEB with 48 days' annual unavailability of the H-2 vehicle. Via a seasonal matching analysis, it can be found that the H-2 vehicle integrated Hy system has a significant effect on alleviating the monthly surplus on-site REe generation. By relieving the condition of discharging the Hy storage by the fuel cell, both the on-site surplus REe and energy shortage will be further reduced and the cogenerated heat from the Hy system can be increased. Therefore, the research approves that it is technically feasible to simultaneously meet the zero-emission fuel requirement of the Hy vehicle, the convenient accessibility of the H-2 refuelling station, the fulfillment of the zero energy balance of the building, and the highest matching capability between generation and demand.
