– In this study, an energy management model is presented for the economical operation of a hydrogen-based country house (CH), which earns its living from fishing activities, without being affected by power outages. The CH is equipped with a fuel cell (FC), electrolyzer (EL), tank, photovoltaic (PV), wind turbine, and hydrogen-based technologies including a hydrogen-powered fishing boat, off-road vehicle, motorcycle, boiler, and hob. A hydrogen-based CH can reduce carbon emissions by minimizing fossil fuel use and harnessing renewable energy. Economically, it lowers energy costs and enhances local employment while increasing energy independence for the community. The optimization problem related to the energy management of the CH is addressed through the mixed-integer linear programming (MILP) method. This is the first study in the literature to discuss the sustainable and economic operation of a CH with hydrogen technologies without being affected by outages. Uncertainties are handled with the stochastic method. Considering that the CH is located in Edirne, Türkiye, various case studies are conducted with real data. According to the test results, the proposed model ensures the economic operation of the CH, as well as its sustainability in terms of energy, and facilitates its uninterrupted and environmentally friendly operation. In case studies involving RES, costs and emissions are lower, reducing costs by 66.8% even during outages. In situations with grid outages, the FC can meet the entire energy demand, preventing any interruptions in the operations of the CH. The study highlights that integrating a 10-kW wind turbine can reduce costs by nearly 50%, making it the most effective element and more effective than the PV system. EL efficiency has a major impact on system cost, with a drop from 75% to 60% leading to a 58% cost increase. Additionally, the inclusion of RES demonstrates a reduction in costs and carbon emissions by 0.088 metric tons. One of the most important results obtained from the study is that with the proposed model, the CH can operate uninterruptedly even during a one-day outage.
