IMPLEMENTATION OF A HYBRID ENERGY SYSTEM COMBINING RES AND H2 IN AN OFFICE BUILDING IN LAVRION GREECE
More than 40% of the total energy consumed in the EU is used to cover the needs for heating, cooling and electricity of buildings. As the major part of this energy is produced from combustion of oil and natural gas, the Building Sector is a major contributor to Green-House Gas (GHG) emissions. To contribute to the realisation of the objectives set by the EC for the reduction of GHG emissions and the increase of the share of renewable energy, the trend for the Building Sector is to move from fossil fuels based energy production to the use of renewable energy sources (RES) and clean fuels to produce the required energy to cover the building energy needs. However, in order to ensure continuous operation of energy systems based on RES it is necessary to find a proper way to balance the intermittent nature of RES. In this scope, hydrogen (H2) is examined as the most appropriate energy storage medium, mainly due to its high energy density by mass and the fact that when burnt the only byproduct is water. In this frame, this paper presents a new concept for the development of an intelligent, self-sustained and zero CO2 emission hybrid energy system to cover electric power, heating and cooling loads (tri-generation) of either residential/commercial buildings or districts of buildings. In the presented system, the primary energy is harvested from RES and is directly used to cover contingent loads, while the excess energy is converted to H2 to be used as energy storage material and to be further applied as a green fuel to cover the building heating needs through direct combustion or to produce combined heating and electricity by means of fuel cells. A prototype system has already been installed in a @500 m2 office building at the Lavrion Technological and Cultural Park of NTUA, Greece, and is currently in operation. The system design and construction considerations are described in the paper together with monitored data from the system and the building operation. A preliminary evaluation of the system performance based on actual measurements has shown that the application of such a system to cover the energy needs of buildings is feasible.
