  • The potential for integration of hydrogen for complete energy self-sufficiency in residential buildings with photovoltaic and battery storage systemstechnologies [Elektronski vir]
    Lokar, Jan ; Virtič, Peter
    This paper presents an analysis of energy production in a pilot building located in Slovenia,which is a typical residential house with an installed photovoltaic (PV) system and pilotbattery storage ... system. Energy management system gathers data from smart meters every15 min. As the pilot building location is in central Europe, complete energy self-sufficiencycannot be provided. The most problematic period of energy production with photovoltaicsystems is winter. Solar radiation during the winter is much lower than in the summer andsometimes snow covers photovoltaic panels and disables energy production. Energy pro-duction and energy consumption are analyzed for one year. This study shows that com-plete self-sufficiency can be achieved by supplementing photovoltaic systems withhydrogen fuel cells. The amount of hydrogen, which would suffice for complete self-sufficiency for the whole period, is calculated according to the analyzed data. A synergybetween photovoltaic system and hydrogen fuel cells is a step forward to complete self-sufficiency with renewable energy sources. The share of self-sufficiency of a hybrid PVfuel cell system would be 62.13%, meaning that there is no possibility for complete self-sufficiency from the pilot system. The shortage of hydrogen is 144.24 kg for one year andfor achieving complete energy self-sufficiency, PV system should be bigger. A hybrid sys-tem with photovoltaic system, battery storage system and hydrogen fuel cells can be asolution for complete self-sufficiency. From an economic point of view, such systems areaccessible for commercial use. The initial investment is relatively high, because of the highcost of the hydrogen storage tank.
