Abstract:
Decentralized renewable energy systems for the supply of alpine huts are important landmarks on the path towards reaching Austria’s climate and energy policy goals. Energy production with renewable energies reduces CO2-emissions. Moreover, an independency of resources and cost saving can be achieved. The aim of this thesis is to develop a 100% renewable energy concept to supply the so called Polinikhütte, which is chosen as a practical example. Furthermore, data from other alpine huts that use renewable technologies are collected for comparison with the new concept. The question if the usable roof area of the Polinikhütte is large enough to meet the demand, is simulated with a computer program. Four battery scenarios are compared. With the help of a cost-benefit analysis the technically and economically most reasonable scenario (Scenario 2) is selected: a photovoltaic generator with 8,4 kWp plus 12-kWh-Li-Ions-battery is able to meet the demand of 1.320 kWh/season. The wood-stove in the guest room and the oven in the kitchen are fired with logs of wood. The demand of wood is approximately 35 m3/season. The domestic hot water is primarily heated with heat extraction from the kitchen oven. The surplus electricity of the photovoltaic generator is used to heat the water as a secondary source. In addition, there are more renewable technologies which can be used to generate electricity like hydro power and wind power. Biomass, but also heat pumps and solar thermal energy can be used for heating up alpine huts. Economic efficiency calculation shows that after using the renewable concept for seventeen years cost savings can be achieved. While using the new concept 72-77% of CO2-emissions can be reduced in comparison to the current state. That means 4,5 tCO2/season would not be emitted.
