Biography

Prof. Dr. Jörg Worlitschek (* 1970) studied chemical engineering at the University of Erlangen and graduated ‘with honors’ from the Technical University of Berlin in energy and process engineering. He worked at the Institute of Biotechnology in Berlin and in the context of a research fellowship at the University of Pusan in South Korea. From 1999 to 2003 he was at the Institute of Process Engineering at ETH Zurich as Assistant and made a PhD in the field of Thermal Process Engineering (Optimization of Batch Crystallization). From 2003 to 2012, he worked at Mettler Toledo in USA and Switzerland. He led areas for Automated reactors & calorimetry (heat of reaction) as well as for laboratory & production software. Since February 2012, Jörg Worlitschek is at the Lucerne University of Applied Sciences & Arts. 
He is the founder of the Competence Center Thermal Energy Storage and his research focuses on crystallization processes, heat and mass transfer in two-phase systems and the assessment of energy storage in the energy system. During 2015 to 2020, he was the program director of the Master of Science in Engineering at the Lucerne University of Applied Sciences and Arts. Since 2020, it is co-founder and part of the SpinOff Cowa, which enables compact energy storage in combination systems of heat pumps with a PV or solar system, among others.

The CC Thermal Energy Storage focuses on the development of heat and cold storage and possibilities to achieve temperature stability in devices, as well as their technical-economic assessment.
