Biografie

Jörg Worlitschek (*1970) studierte an der Universität Erlangen Chemie-Ingenieurwesen und schloss an der Technischen Universität Berlin das Studium der Energie- und Verfahrenstechnik mit Auszeichnung ab. Er arbeitete am Institut für Biotechnologie in Berlin und im Rahmen eines Forschungsstipendiums an der Universität Pusan in Südkorea. Von 1999 bis 2003 war er am Institut für Verfahrenstechnik der ETH Zürich als Assistent tätig und promovierte auf dem Gebiet der Thermischen Verfahrenstechnik (Optimization of Batch Crystallization). Von 2003 bis 2012 war er bei der Mettler Toledo AG in USA und der Schweiz. Er leitete Bereiche für Automatisierte Reaktoren & Kalorimetrie (Reaktionswärme) sowie für Labor- & Produktionssoftware. 
Seit Februar 2012 ist Jörg Worlitschek an der Hochschule Luzern - Technik & Architektur tätig. Er ist Gründer des Kompetenzzentrums Thermische Energiespeicher und beschäftigt sich in seiner Forschung mit Kristallisationsprozessen, Wärme- und Stoffübertragung in Zweiphasensystemen und der Beurteilung von Energiespeichern im Energiesystem. Während der Jahre 2015 bis 2020 war er Studiengangleiter des Master of Science in Engineering an der Hochschule Luzern. Seit 2020 ist es Mitgründer und Teil des SpinOffs Cowa, welches die kompakte Energiespeicherung u.a. in Kombisystemen von Wärmepumpen mit einer PV resp. Solaranlage ermöglicht.

Das CC Thermische Energiespeicher fokussiert sich auf die Entwicklung von Wärme- und Kältespeichern und Möglichkeiten der Erreichung von Temperaturstabilität in Geräten, sowie deren technisch-wirtschaftlichen Beurteilung.
