2021: Zweifeldspeicher – Improving the efficiency of seasonal energy storage for heating and cooling applications

The storage of heating and cooling in borehole thermal energy storages (BTES) is an innovative way of storing energy. In conventional approaches the entire BTES operates on one temperature level. Based on this in the project “Zweifeldspeicher“ it is investigated whether the operation of two partial BTES with different temperature levels has energetic and economic advantages. The presumption that there are system set-ups where these advantages are significant is essential for the investigation. In this regard the presumed influencing factors are load profiles for heating and cooling, the necessary temperature levels, the absolute project size, the land price etc. Methodically reference systems are defined and dynamically simulated. For the investigation of the economically feasible aspects a dynamic model of profitability is created which enables variation of parameters and sensitivity analysis. The project results provide general suitability factors for the partitioning of BTES and enable an evaluation of gains in efficiency. The research project is carried out under the direction of the Geological Survey of Austria and with the participation of the AIT Austrian Institute of Technology GmbH, ENFOS E. U. as well as the technical university of Vienna, Institute for energy systems and thermodynamics. The one-year BTES project is sponsored by the Klima- und Energiefonds, represented by the Austrian Research Promotion Agency with the project number FO999888399.

2021: Project: Market survey of energy storage technologies in Austria (MSSP2020)

A research project of the Technikum Wien GmbH, ENFOS e. U., AEE INTEC and BEST GmbH on behalf of the Federal Ministry for Climate Action, Environment, Energy, Mobility, Innovation and Technology in the period from November 2020 until September 2021.
The conversion of energy through humans has always been linked to the topic of energy storage. No matter whether stocks are built up, fuels are stored, service water is heated in boilers, natural gas is pressed in depleted deposits or water is collected or pumped into high storages – energy storages are established along the relevant value chain or energy conversion chain and they have played an important role for mankind from the beginning.
Through the rebuild of the historically grown national energy system of central units for converting fossil energy to decentralized structures for converting renewable energy, the topic energy storage gets a different quality.
Regarding the energy conversion chain this deals with energy-service related energy storage as for instance the heat storage in building masses for supplying comfortableness for users or the storage of electrical energy of photovoltaic installations for later use spatially close to the storage.
From the wide area of innovative energy storages in the present project the stationary battery storage devices for the maximisation of the private consumption in PV-systems, the large heat accumulators for local and district heating systems, the thermal activation of buildings and the area of innovative storage systems have been chosen for the first market survey. The historical market diffusion of these technologies is surveyed empirically in this project and documented up to 2020. As it is the first-time processing of the topic the studies reach from the definition of the objects of investigation involving further experts to the development of survey structures and instruments up to practical surveys, data processing and interpretation of the results.
The project MSSP2020 provides the basis for planning and decision-making for the design of energy-, and environmental-, technological- and research-political instruments. Furthermore the results are suitable for making market strategical considerations and for reflecting on the current technological design. Therefore primary target groups are political decision makers as well as persons from research, development and the production industry.

2018: Renewable Energy 2018 - Economic and climate relevant figures and aspects of Austria and of the European Union

The energy and climate policy of the European Union aims at the limitation of the global warming to 2 degrees Celsius compared to the pre-industrial level and it aims at the transformation of the European economies in sustainable economic systems. Based on the first climate and energy package for 2020, the frame for a long-term EU climate and energy policy up to 2030 was decided by the Heads of State and Government of the EU member states in 2014. This agreement contains a decrease in greenhouse gas emissions by at least 40% compared to the level of 1990, an increase of the share of renewable energy sources to at least 27%, and an increase of energy efficiency by at least 27%. The long-term plans of the EU by 2050 aim at an extensive decarbonization of the European economy whereby a decrease in greenhouse gas emissions by 80% compared to the level of 1990 is planned. In order to reach this ambitious goal all sectors within the frame of their technical and economic potential have to make significant contributions. The present brochure presents selected indicators which make the progress on the path into a sustainable future quantifiable. Its aim is to show structural developments of the use and production of energy in the EU. The documented figures thereby refer to the latest available figures of 2016. Section diagrams show the structural variety of the EU member states, and the time series diagrams for chosen countries make the evaluation of essential trends possible.

2018: Development of a sustainable heating and cooling system for the Smart Anergy Quarter Baden (SANBA)

The former military camp “Martinek-Kaserne” south of Baden, close to Vienna has not been used by the Austrian Armed Forces since 2014. On the about 42 ha area there are buildings protected by cultural heritage from the 1930s, some newer buildings as well as big open space. In the SANBA project three buildings scenarios were defined. The three scenarios reach from a mere use of the buildings protected by cultural heritage (scenario MINI), to additional moderate new buildings (scenario MIDI), up to an increased concentration afterwards with mixed use (scenario MAXI). The research focuses on the development of a sustainable heat and cooling supply system for the quarters in the three scenarios. The basis for the supply of heating and cooling is the use of low temperature industrial heat loss from the neighbouring dairy NÖM AG through anergy grid, borehole storage and heat pump installations. The problem is worked on by nine project partners whereas the common development of communicative dynamic simulations tools is an important scientific challenge. In this context the ENFOS company is concerned with the economical system analysis. The results of the research project make a multidimensional evaluation of the concrete development scenarios possible and are the basis of decisionmaking for further steps. Furthermore numerous project results can be generalised for similar constellations.

2018: Implementation of a circular economy for photovoltaic

Due to the historical market development of photovoltaic systems in the EU-memberstates it can be foreseen that in the following decades a great amount of obsolete installations of various types will accumulate. The system components contain valuable materials as indium, silicon, silver, copper, glass and many others. Therefore in the Horizon 2020 project "CABRISS" 16 European industrial and research partners are developing processes for recapturing these valuable materials and are researching innovative processes for reprocessing the valuable materials in new photovoltaic systems. The research and development activities may be structured in the fields crystalline silicon technologies and thin-layer technologies. The results show the technical and economical feasibility of numerous subprocesses and of the total system and show potentials for the reduction of the cumulated energy input, the production-related greenhouse gas emissions and the energetic payback time of photovoltaics made of recycled materials.

2015: Empirical life cycle analysis of solar thermal and photovoltaic systems (RIOSOLAR)

As solar thermics and photovoltaics were brought onto the market in the 1970s they had partly unfavourable life cycle key figures. A long energetic payback time and high life cycle costs were in particular for photovoltaic systems a great diffusion constraint for a long time. Against this background researchers of the Technical University of Vienna and pupils of the HTL Wiener Neustadt in the research project RIOSOLAR were concerned with the historic development of the life cycle key figures and with the empiric analysis of 60 systems in operation in the wider area of Wiener Neustadt. During the survey there was a focus on the actual energetic payback time and the actual CO2 avoidance costs and technical as well as economical developmental areas up to 2030 were outlined.

2013: Solar micro heat grid with seasonal geothermic thermal storage (GEOSOL)

Affordable seasonal thermal storage make a fully solar heat supply of residential buildings and industrial buildings possible. Already implemented pilot and demonstration installations in the area of water reservoirs and earth storages show the technical feasibility of these systems. The project team consisting of the Technical University of Vienna, the Geological Survey and the HTL Wiener Neustadt analysed in the project GEOSOL model systems of buildings, solar thermic installations and the thermal storage in the earth. Methodically model systems were reproduced with computer simulations and for the testing of practicability concrete case scenarios were analysed with the pupils of the HTL Wiener Neustadt. The project results show concrete qualification criteria for certain systems which have especially technical and structural parameters. The potential for application in the Austrian building stock is basically high whereas the implementation of pilot and demonstration installations as a validation of the used models is recommended beforehand.

2010: Heating 2050

The development of future heat demand and the future heat supply of buildings is of major importance for achieving national goals in the areas of climate protection and renewable energy. For this reason in the project Heating 2050 the analysis of the long-term development of the Austrian buildings, their heat demand and the cover of the heat supply up to 2050 is made. Residential buildings and non-residential buildings of various categories are thereby considered. For this purpose the energy service areas space heating and heat for service water heating are examined. The developments are illustrated in scenarios and analysed. The results show that for a long-term minimisation of the energy consumption for space heating and service water heating a bundle of measures is necessary. The securing of a high renovation quality is one of the most important points. A very good heat insulation, the creation of low-temperature heat distribution systems and the exclusive use of technologies for the use of renewable energy have to be energy politically secured. Moreover the development of technological key components as thermal storage systems with high heat density have great importance among the upcoming system innovations.

2009: Potential of Solar Thermal in Europe

For the first time in 2007 the European Council agreed on an "integrated climate and energy policy" including an "energy action plan" for the years 2007 to 2009. As a result the European commission set themselves the goal to increase the percentage of renewable energy in the energy mix unto 2020 by 20 % whereby a specific national target for each memberstate was agreed. As 49 % of the final energy demand of the European Union fall on the heat sector, renewable heat will have to make a major contribution to reach the goal. Therefore the potentials for solarthermal solar energy utilization in Europe are examined and documented in the present survey. Detailed analysis are made for Austria, Denmark, Germany, Poland and Spain. These countries represent 36 % of the entire population of the EU and enable a differentiated view according to climate zones, states of technology diffusion and according to various energy political framework conditions.

2007: Energy centres on the basis of stationary fuel cells (BIOVISION I)

The decentralized use of renewable energy opens up additional potentials of sustainable available resources. An example for this is the conversion into electricity of biogas in conventional communal heating stations with combustion engines. The energy and exergy efficiency of this technical concept can be significantly increased through the use of stationary fuel cells. Multifunctional used fuel cells develop a very high overall efficiency and show an especially high efficiency for conversion into electricity. In the project BIOVISION I this circumstance is analysed on the basis of different model systems. Therefore user profiles for potential operators are defined, the necessary reforming and purification of the fuel cells is investigated and profitability analyses are made. The results are edited and documented in regard to a selection of potential pilot and demonstration plants.

2005: Development of a solar radiation operated Stirling machine

The Stirling machine was a heat engine invented by the Scottish pastor Robert Stirling registered for patent in 1816. Since then various civil and military uses have been found for the machine due to special operating properties as the vibration free operation or the suitability for different energy supplies whereas the heat is supplied practically exclusively on a high temperature level. To demonstrate the use of this classical heat engine in the area of renewable energy a solar powered lowtemperature Stirling machine has been developed and built for the Technical Museum of Vienna in the present project. The demonstration Stirling machine is exhibited in the public collection of the Technical Museum of Vienna. The necessary driving power is supplied by the stream of light of a spotlight. The operation of the machine is ensured from a difference in temperature of 40 Kelvin.

2004: Measures for the minimization of rebound effects for renovation (MARESI)

The energetic renovation of buildings is seen as an effective measure for attaining national and international agreements on climate protection. For renovations the energetic cost-saving effect remains in practice below the expected pre-estimated results. This phenomenon is discussed since the 1980s whereas a comprehensive treatise or even a detailed quantitative analysis of these socalled "rebound effects" is missing. In the present research project two methodical approaches are implemented. On the one hand 12 case studies of representative renovation projects in Austria are made in order to examine qualitative aspects of the user behaviour and the impacts on the success of the renovation. On the other hand an analysis of horizontal micro data of approximately 500 Austrian households is made to quantify qualitatively observed effects.

2001: Renewable energy sources and energy consumption behaviour

The use of renewable energy sources in private households is seen as an important approach in reaching the set energy and climate targets. How much the usage of technologies for the use of renewable energy sources affects the actual energy consumption, if the corresponding households have a typical energy consumption behaviour and if these households make a significantly more economical use of energy than conventional households has hardly been examined up to now. Therefor an empirical econometric analysis of detailed cross section data of 101 Austrian households with technologies for the use of renewables and 177 conventional households, single family houses in each case, is made in the present survey.

1998: Influencing parameters on the energy consumption of households

In order to develop successful energy political strategies a good knowledge of the influencing parameters on the energy consumption and their interactions is necessary. Therefore the present survey examines with an interdisciplinary approach the influencing parameters on the energy consumption of households. Comprehensive cross section data of 500 Austrian households form a basis which are analysed with econometric modelling. Economic, technical, structural, sociological parameters and parameters of behaviour for the energy service sectors space heating, water heating and household appliances and for the aggregated sectors of total energy and total power consumption are evaluated.
