CityStore - Sondierung des wesentlichen F&E-Bedarfs zur Optimierung von städtischen Energiespeichern in integrierten Energiesystemen
In CityStore wird erstmals ein innovativer Ansatz zur räumlichen Verortung von Speicherbedarf und -potentialen verfolgt. Dies inkludiert die Evaluierung der konkreten Herausforderungen und Voraussetzungen sowie die Identifikation von sinnvollen Speichertechnologien und -kapazitäten. Dazu werden Modellrechnungen für die Vorzeigestädte Graz und Weiz durchgeführt und die Verallgemeinerungsfähigkeit der Ergebnisse anhand der Follower-Region Südburgenland untersucht. Die Resultate sollen optimierte Planung und Realisierung von städtischen Energiespeichern ermöglichen – wodurch zielgerichtet in Energieinfrastruktur zur Umsetzung von (lokalen) Klima- und Energiezielen investiert werden kann.
Move2Grid – Implementation of regional energy-supply-concepts by hybrid coupling
Based on the results of the national-funded exploratory projects called “Smart Exergy Leoben”, and “Energy Sponge Bruck”, the present implementation project aims at analysing how local, renewable resources support the supply of electric mobility in Leoben in the long term and to integrate it into the municipal distribution grid in a good economic sense.
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.
ecoRegeneration: Development of a "Merit-Order" in order to assess regeneration heat for geothermal probes within urban residential neighbourhoods
In urban residential areas there are not enough active-cooled usages, to use the waste heat of the cooling process as required regeneration heat for geothermal probes; free cooling of the apartments is not sufficient. The project is developing various options (waste heat from commercial uses in the ground floor zones of residential buildings, by using waste heat of data centres, additional installation of heat generation systems for regeneration) within the urban settlement area, business models and is calculating life-cycle-costs of all solutions. The result should be a kind of "merit order" for regeneration heat.
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.

StromBIZ - demonstration projects: business models for decentralized electricity generation and distribution
Feasible business models to utilize locally generated renewable energy are expected to induce a tipping point for the "Energy Turnaround" in Austria. Within the proposed project a number of demonstration PV plants on residential and non-residential buildings had been realized. On this basis new approaches of business cases had been developed, implemented, tested and disseminated.
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.
solSPONGEhigh - High solar fraction by thermally activated components in an urban environment
Within this project the intensive use of thermally activated building elements (TABs) as an additional thermal storage in different buildings, with solar technologies (thermal, PV) preferred for energy supply, was investigated.

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.
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.
