Performance of Hydrogen Technology for Power Supply of Passive House

Abstract:

For welcoming a future economy based on hydrogen technology, the paper presents the results of the study case that, for the first time in Romania, simultaneously tackles two concepts with remarkable role in the efficiency and decarbonisation of energy generation systems in residential buildings: hydrogen fuel cell and passive house. For power supply of passive house were created and simulated virtual operating conditions of a energy system as stand-alone type, the hydrogen technology has been integrated into hybrid solar - wind energy system inside of which to take over the storage function by electrolytic hydrogen obtained locally inside the system by exploitation of available renewable sources and use it on fuel cell that serves as a back-up to cover the peak load demands and intermittencies caused by weather conditions. The aim of this study is to demonstrate the capability and feasibility on energy, economic and environmental performance of hydrogen technology for power supply of passive house. The main results of the study: studied passive house, with an surface of 160 m², located in Cluj - Napoca, has a total annual load value equal to 42,24 kWh/m²∙year, being of 75% lower than that of a newly constructed building in the European standard, the annual energy production of the power system is performed by the photovoltaic panels with a percentage of 54,55%, 35,95% by wind turbines and 9,50% by fuel cell. Storage and use the solar and wind renewable energy through electrolytic hydrogen is in proportion of 61,80% and the carbon footprint of the whole building - energy system is with 81,30% lower than in a traditional building energy aided by a classical system.
