CityStore - Sondierung des wesentlichen F&E-Bedarfs zur Optimierung von städtischen Energiespeichern in integrierten Energiesystemen

CityStore pursues a first-of-its-kind, innovative approach on spatial location of storage needs and potentials. This includes the evaluation of concrete challenges and prerequisites as well as the identification of useful storage technologies and capacities. Model calculations for the model cities Graz and Weiz will be carried out. If, and to which extent, the results can be generalized will be investigated in the Follower Region South Burgenland. The results should enable optimized planning and realization of urban energy storage facilities – thereby enabling targeted investments in energy infrastructure to achieve (local) climate and energy targets.

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.

Heat Harvest - Harvest of urban solar excess heat from buildings and surfaces to avoid summer overheating in cities

"Harvest" of solar urban excess heat from building surfaces, sidewalks, streets and squares to avoid urban heat islands by lying flat absorber pipes, which are then fed into geothermal probe storage tanks for later use as a source for heating buildings.

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.

Manage_GeoCity - Development of a method for the coordinated management of geothermal energy in urban areas

Based on the urban region Graz a method had been developed for the coordinated use and management of shallow geothermal energy for heating and cooling as well as seasonal heat storage in urban regions. Ground water flow, different geologic conditions, heating and cooling demand, heat input from solar collectors and industrial waste heat and the possibilities of seasonal heat storage in the subsurface were considered.

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.

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.

PESI - Paradigm shift in urban energy systems through synergies with industry

Analysis of different options for the use of industrial surplus energies of various shapes (waste heat, waste water, waste) and renewable energy sources in the industrial sector (e.g. solar panels on roof surfaces) in adjacent urban areas, which act as an "energy sponge". Based on real consumption and availability data, a simulation model was created and opportunities for synergies were documented.

In the course of the project, the conceptual design of a zero-emission or plus-energy business park in Weiz with a focus on photovoltaics and fuel cells in combination with a Renewable Energy Community (E-EGe) had been carried out. By establishing the park on a "greenfield", all structures can be created according to the requirements of the E-EGe.

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.

SeasonalGridStorage - Innovative seasonale thermal storages for urban district heating grids

Sensible storages, which are currently used in district heating networks for seasonal storage of excess heat (e.g. from solar thermal or industrial waste heat), exhibit high space demand, investment costs and heat losses. Within this project, concepts for using innovative storage technologies, e.g. thermochemical storages (TCS) having high heat densities and enabling pressure- and lossless storage, were developed and analyzed on a technological, economic and ecological basis. Additionally, the regulatory framework has been evaluated.

TFlex - Temperature-flexibilisation in low-load operation of local district heating systems

Within the research project TFlex it was checked if the losses adherent to small district heating networks during low-load periods can be reduced. One possible solution is by deactivating the network and supplying the customers from previously charged decentralized storages. The optimal clustering of the storages and the possibility of solar-charging the storage were calculated with the aim of a guaranteed one-hundred percent heat supply.
