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.
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.
ÖKO-OPT-QUART - Economically optimized control and operating mode of complex energy networks of future city districts
In the project ÖKO-OPT-QUART energy-based, economic and control-orientated models will be developed in order to simulate the operating mode of complex, sustainable energy networks in city districts. For an exemplary configuration these models will be combined to an overall model which allows a realistic economic comparison of different control strategies. The final goal of the project is the development of a method for the systematic design of cost-optimized, predictive control strategies for complex energy networks in city districts.
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.
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.

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.
Market survey of energy storage technologies in Austria (MSSP2020)
Stationary battery storage devices for the maximisation of the private consumption in PV-systems, large heat storage for local and district heating systems, thermal activation of buildings and the area of innovative storage systems have been chosen for the first market survey within this project. The historical market diffusion of these technologies is surveyed empirically and documented up to 2020.

solSPONGEhigh - Hohe solare Deckungsgrade durch thermisch aktivierte Bauteile im urbanen Umfeld
Im Forschungsprojekt solSPONGEhigh wurde die intensive Nutzung von thermisch aktivierten Bauteilen (TABs) als zusätzlicher thermischer Speicher in verschiedenen Gebäuden unter vorrangigem Einsatz von Solartechnologien untersucht. Die Arbeitshypothese ging davon aus, dass durch die Aktivierung und Nutzung der bauteilimmanenten thermischen Speicher eine Deckung des Gebäudeenergiebedarfs mit Solartechnologien von bis zu 100 % erreicht werden könnte.

Manage_GeoCity: Entwicklung einer Methodik zur koordinierten Nutzung und Bewirtschaftung der oberflächennahen Erdwärme in urbanen Räumen
Anhand der Modellregion Graz wurde eine Methodik für die koordinierte Nutzung und Bewirtschaftung oberflächennaher Erdwärme für Wärme- und Kühlanwendungen sowie saisonaler Speicherung in urbanen Räumen entwickelt. Dabei wurden Grundwasserströmungen, unterschiedliche geologische Verhältnisse, Wärme- und Kühlbedarf, Wärmeeintrag von Solaranlagen und betrieblicher Abwärme und die Möglichkeiten der saisonalen Speicherung von Wärme im Untergrund berücksichtigt.

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.
