About the Department of Energy Technology
The Department of Energy Technology aims at contributing to welfare and development through world class research and education in innovative energy technologies and systems, and promotion of the energy sector transition towards sustainability.
Our research
The Department of Energy Technology at KTH addresses the transition to sustainable energy systems through a combination of fundamental science, advanced engineering, and systems-level analysis. We cover the full spectrum from thermodynamic processes and energy conversion technologies to integrated energy systems and policy-relevant modelling.
Within the Division of Applied Thermodynamics and Refrigeration at KTH, research focuses on fundamental heat transfer, thermodynamics, and thermal systems such as heat pumps, refrigeration, and indoor climate technologies. This work underpins efficient energy use in buildings, industry, and infrastructure.
The Division of Heat and Power Technology at KTH develops and analyses components and systems for thermal and mechanical energy conversion. Research spans turbomachinery, thermal processes, and the integration of renewable energy sources – such as solar, wind, and biomass – into applications ranging from industrial processes to urban energy systems.
The Division of Energy Systems at KTH takes a broad, interdisciplinary perspective, linking technology, policy, and innovation to sustainable development. Research includes energy system modelling, circular economy, climate-energy-land interactions, and the role of energy in global development, often in collaboration with international organisations.
Together, these divisions enable a holistic approach to energy research – combining detailed understanding of physical processes with system-wide analysis – to develop resource-efficient, low-carbon, and resilient energy solutions for society.
Divisions
Our organisation
The Department of Energy Technology has a board consisting of the Head of the Department, Division Heads, the Study Principals and Programme Directors.
Our education
The courses and programs offered at the Department provide a solid basis for careers in the power industry, manufacturing and construction industries, consulting, government agencies, and for advanced research in the broad field of applied energy technology. Topics are intimately tied to our research activities and include thermal energy conversion, polygeneration, turbomachines, heating and ventilation technology, refrigeration and heat pump technology, biomass, solar energy, energy systems analysis, energy resource assessment, energy policies, and climate change.
The education is a common responsibility at the Department level, but the responsibility for most courses is handed over to the Divisions.
