AR-HES-B – Energy storage, production and recovery of valuable substances in wastewater treatment plants
AR-HES-B develops technologically based concepts of municipal wastewater treatment plants in order to convert them from energy consumers into a hybrid energy provider, energy storage and a provider of resources. The concept enables wastewater plants to turn into an important platform in the regional energy and mass transfer.
SOFC4City - SOFC-waste heat utilization for buildings and industry
In this project the application of a solid oxide fuel cell (SOFC) for energy supply (heat and power) of urban areas will be investigated. Due to the high temperature level of the produced heat it would be possible to use this heat for the energy supply of different heat and power consumers (residential buildings, industrial plants, etc.). One aim is to provide the SOFC-heat at several temperature levels in order to establish the advantages of the fuel cell. On the one hand the legal and market-based conditions will be evaluated, on the other hand the technological feasibility will be scoured by the use of CFD-simulation of the heat production.
OPEN HEAT GRID - Open Heat Grids in urban hybrid systems
The primary research topic of OPEN HEAT GRID was to investigate the possibilities of enforcing the feed-in of industrial waste heat into existing district heating networks. The project results show that excess heat is not for free: despite minimal variable costs, the investment costs need to satisfy usual payback periods. The analysis shows that there is no need for a regulation in the sense of a feed-in obligation or market liberalization. However, from an economic point of view, information asymmetries exist, which may lead to irrational decisions.
Energy-Sponge-Bruck (Energieschwamm Bruck an der Mur)
The aim of the exploration-study for the urban region Bruck/Oberaich "Energieschwamm Bruck" or "Energy-Sponge-Bruck" was to establish clear and stringent basics for a flexible development of the future energy system. Therefore an energy development concept as well as a cadaster for short-term implementation measures had been applied. The structured, Bruck-based approach acts as framework for a general energy-conception-method, valid for small and medium urban regions with 10,000 to 20,000 inhabitants.
CiQuSo - City Quarters with optimised solar hybrid heating and cooling systems
The project CiQuSo aimed to develop, evaluate and optimize concepts for solar energy systems to provide energy for buildings and cities. The applicability of the developed methods and concepts were shown as an example at Itzling, a part of Salzburg city.
P2H-Pot - Potentials, economic feasibility and system solutions for Power-to-Heat
P2H-Pot has identified economically feasible potentials for Power-to-Heat (P2H) in urban regions. The suitability of different technical system configurations were investigated using thermodynamic simulation and considering experiences from Scandinavian cases. The assessment of short, medium and long term relevance and economic feasibility of P2H were accomplished by simulating model-based scenarios up to 2050 of the Austrian and German electricity and heat market. In cooperation with a district heating company three case studies have been carried out.
Using buildings as energy storage - Monitoring project: Detached house H and detached house F Energy source wind power – Energy source solar power
Monitoring and comparison of performance of thermally activated building components in two similarly built, inhabited detached houses with different energy sources (wind and solar power). The functionality of energy supply through wind power or solar energy will be investigated as well as the verification of the practicability of self-regulating system control due to building temperature behaviour. The results provide an insight into the calculation assumptions, system control and feasibility of the smart grid technology.
LTS Flywheel - Long Term Storage-Flywheel: New approaches for increasing the economically usable storage time and safety
Development of the fundamentals for a Long Term Storage (LTS)-flywheel for decentralized storage of electrical energy (e.g. from wind or PV power plants), with a significant increase in storage time (goal: 12 hours) and safety, featuring low system costs. Therefore, the LTS-Flywheel is an essential contribution to the building of the future.
Symbiose-4-I&C - Optimal decentralized hybrid storage technologies among different energy systems -4-Industry and Commerce
The project Symbiose-4-I&C analysed the coupling of existing energy networks/-carriers, established on centralized energy network nodes or directly next to a consumer (households, industry and commerce) and the benefits of applying decentralized storage technologies. The optimal position, dimension and the right storage and conversion technology and an optimal energy wide operation of larger consumer groups were estimated for an urban model region.
