Energy systems

Research in energy systems is principally conducted within three areas: district heating, wind power and bioenergy. A common theme regarding all three areas is resource efficiency and renewable energy supply, such as through heat recovery in district heating systems, power generation with wind turbines and biogas production within the agricultural sector. The research is multidisciplinary and is based on methods and theories, for example from energy system analysis, geographical information systems, physics, biology, statistics, economics, mechanics, curriculum, thermodynamics, acoustics,
electricity and microbiology.

Research in energy systems is principally conducted within three areas: district heating, wind power and bioenergy.

District heating

The research covers a number of sub-areas, primarily the role of district heating from an overall energy system perspective, both in Sweden, Europe and globally. Another sub-area is heat and cooling market analyses, with regards to both needs and assets. A third sub-area concerns conceptual technology development of the low-temperature systems of the future (fourth-generation district
heating) and data mining.

Economics in distribution and network investments, as well as future needs for heating and cooling, are also studied. The analyses show, among other things, that surplus heat from power generation and energy-intensive industrial processes could be utilised, thus reducing the need for added primary energy.

Renewable energy

Renewable energy is largely focused on studies of electricity generation and distribution of electricity from wind power, solar energy, bioenergy and others. For example, various aspects of vertical axis wind turbines are studied.

The department has access to several different wind turbines, for example through a collaboration with Uppsala University. Using the turbines as an experimental base, the department studies mechanisms behind how sound is generated in wind turbines and how turbulence in the wind affects performance, among other things.


Research on biogas is aimed at optimising the management of substrates and bio-fertilisers, and creating added value in the agricultural sector, through solutions that can increase production and profitability.
