A potential solution for stand-alone power generation is to use hybrid energy systems with hydrogen energy storage. In this paper a pre-feasibility study of using 100 % renewable hybrid energy system (solar and wind energy source) with hydrogen technologies (electrolyser, hydrogen tank, fuel cell) for a reference household application in Portorož (Slovenia) is explained. HOMER software tool is used for simulations and optimal energy system identification, where geographical location and availability of energy sources, load dynamics, component technical and economical characteristics were considered. Experimental work was performed on existing laboratory facilities with hydrogen technologies. The optimal feasible system capacity (34 kW), with lowest total net present value (138.452 EUR), is approximately 8- 2 times larger than peak power demand (3,8 kW). Experiments confirmed adequate numerical model design with only 3 % deviation in results.
