About the position

The Department of Energy and Process Engineering at the Norwegian University of Science and Technology has a vacancy for a PhD candidate in Advanced High-Temperature Heat Pump Systems. The position focuses on developing advanced solutions for multi-level recovery and upgrading of industrial waste heat using absorption-based high-temperature heat pump technologies. The PhD candidate will be part of a dynamic and collaborative research environment working on combined heat and power.

The project offers opportunities to contribute to research with strong relevance for the decarbonization of industry, while gaining expertise in modelling, analysis, and potentially experimental investigation of advanced heat pump systems.

The successful candidate will work closely with academic staff and may collaborate with industrial partners, providing valuable experience and strong career development opportunities within energy and process engineering.

Are you motivated to take a step towards a doctorate and open up exciting career opportunities? As a PhD Candidate with us, you will work to achieve your doctorate, and at the same time gain valuable experience that qualifies you for a further career in higher education and research, in and outside academia.

Your immediate leader will be the Head of Department.

About the project

Industrial processes generate large amounts of waste heat at multiple temperature levels, which remain underutilized due to technological and operational limitations. Efficient recovery and upgrading of this heat are essential for improving energy efficiency and reducing emissions in industrial systems.

This PhD project focuses on the development of multi-level waste heat recovery systems based on absorption high-temperature heat pumps, with particular emphasis on dynamic behavior and system integration. The research will combine dynamic modelling, numerical simulation, and experimental investigation using an existing absorption heat pump/refrigeration test facility.

The study will address the challenges associated with variable operating conditions, fluctuating heat sources, and transient industrial processes. Advanced dynamic models will be developed to simulate system performance, optimize control strategies, and evaluate system response under realistic operating scenarios. Experimental validation will be performed to ensure model accuracy and to improve system design.

The outcomes will contribute to the development of flexible, efficient, and robust thermal energy systems capable of utilizing multi-temperature waste heat, supporting industrial decarbonization and sustainable energy transitions.

Duties of the position

Complete the doctoral education until obtaining a doctorate
Carry out research of good quality within the framework described above
Design, test and optimization in advanced high-temperature heat pump
