Energy Systems

The University of Applied Sciences Wiener Neustadt conducts comprehensive research into aspects of an environmentally friendly energy supply. Our focus is on the optimal integration of renewable energy technologies as well as on processes for the production and conversion of biomass. Within the framework of interdisciplinary cooperation, we conduct research in the usability of energy-relevant products and services on the market. The focus of Energy Management is on advising companies and municipalities with regard to the optimal use of energy.

Topics include strategies for renewable energy plants to participate in energy markets, the development of business models (especially sector coupling and demand side management), supply and logistics concepts for the energetic use of biomass as well as the creation of concepts for increasing energy efficiency in companies and municipalities.

There are various collaborations with research institutions, companies and organisations.

Research Activities


    Establishing a sustainable energy and economic system and dealing with the opportunities and risks of digitization are among the greatest challenges facing our society. BSAIO aims to put these two aspects in relation to each other. The methods from the fields of Big Data, Machine Learning and Artificial Intelligence, which are based on digitization, as well as increasingly powerful optimization algorithms, offer the possibility of operating systems in a more sustainable way and saving resources both in their planning and operation. To this end, all necessary knowledge is to be imparted and the methods are to be applied directly to practical tasks. At the same time, the targeted use of methods based on digitisation for responsible and sustainable use of resources should help to create best practice examples in this area.

  • RealLifeBiomass

    The active involvement of end users in further awareness raising is the key element of WP3. Interested house owners (n=100) are actively involved in measures and methods for the sustainable improvement of air quality and for optimizing the operation of their own heating system. A citizen science approach is chosen (end users collect data on their heating behavior themselves and then forward it to the project consortium), leading to increased end-user awareness.

    Project Partners

    • Bioenergy 2020+
  • Thermoacoustic_HP

    This FFG project examines solutions for heating and cooling in buildings with a thermal power of < 2 kW using a thermoacoustic heat pump. Forschung Burgenland is project lead, Heliotherm industrial partner, FOTEC is responsible for simulation and design of the thermoacoustic device.

  • Thermoacoustic System Study

    In this ESA project, a system for thermoacoustic electricity generators for satellites was studied. In the consortium with Airbus Group Innovation (FR) and Hekyom (FR), led by Surrey Space Technologies Limited (SSTL, UK), FOTEC was responsible for system-level modelling and the development roadmap.


    In this EDA project, hydrogen storage solutions for submarine air-independent propulsion are being investigated.

  • Bio(FLEX)Net

    Due to the benefit of being storable, the production of biogas allows the equalisation of fluctuating energy production from renewable energy sources as wind energy or solar energy. The present project aims to develop adaption measures within a retrofit in order to change the plant operation with the target of offering flexible energy on demand.

  • MH

    This ESA project aims at developing a hydrogen storage solution for a regenerative fuel cell system for satellites in cooperation with Prototech (Norway) and Thales Alenia (France). FOTEC is responsible for the development of the hydrogen storage system.
