Sustainable Energy Systems

The Division of Combustion Engines has long been an internationally leading research environment in the development of new combustion concepts aimed at reducing fuel consumption and lowering emissions. Our research seeks to increase the understanding of combustion processes and how new types of fuels can contribute to even higher efficiency and sustainability. Hydrogen holds a unique position among renewable fuels due to its potential to eliminate harmful emissions. With the so-called argon cycle, where the nitrogen in air is replaced by argon, efficiency can be increased while avoiding emissions of nitrogen oxides.

The Efficient Energy Systems research group develops future sustainable energy solutions with a focus on district heating, district cooling, sector coupling and flexibility. By integrating technology, business models, policy analysis and user behaviour, we contribute to the energy transition in Sweden and internationally. Our research includes the optimisation and development of district heating and cooling systems, energy-efficient buildings and districts, business models for next-generation heating systems, the role of hydrogen in energy integration, and the digitalisation of energy systems through data analytics and machine learning. We also study how battery solutions can be integrated into the electricity system to enhance flexibility and security of supply.
