Third-cycle subject: Energy and Environmental Systems , Energy Technology
Global thermal demands cover 50% of final energy use, largely based on fossil fuels. Thermal Energy Storage (TES) is thus crucial for decarbonizing energy systems. Latent heat thermal energy storage (LHTES) is gaining momentum as a compact TES. Heat pumps, together with TES enable flexible coupling of electrical and thermal sectors. This project aims to develop, design, construct, operate and optimize a pilot-scale LHTES in combined operation with heat pumps at a real heating application (KTH Live-in-Lab). The project includes: phase change material characterization in bench-scale; numerical design and optimization of pilot-scale LHTES (and heat exchanger) configurations; the construction and commissioning of the optimal LHTES; its installation in-combination with heat pumps in KTH Live-in-Lab; and the control and techno-economic optimization of this LHTES-heat pump solution. This is within a European project collaboration, also including internal collaborations between ITM and ABE schools at KTH.
Project details: The project covers all the three TES design phases: material, component and system, and combined operation of TES and heat pumps for real heating applications. The results are expected to bring contributions in Swedish as well as European contexts, to elevate the state-of-the art of LHTES technology as well as its combined operation with heat pumps.

After the qualification requirements, great emphasis will be placed on personal competency.Target degree: Doctoral degree Information regarding admission and employment
Only those admitted to postgraduate education may be employed as a doctoral student. The total length of employment may not be longer than what corresponds to full-time doctoral education in four years ' time. An employed doctoral student can, to a limited extent (maximum 20%), perform certain tasks within their role, e.g. training and administration. A new position as a doctoral student is for a maximum of one year, and then the employment may be renewed for a maximum of two years at a time.Union representatives
