11 — 13 October 2021


The Knowledge Center on Organic Rankine Cycle technology – KCORC has organized the 6th International Seminar on ORC Power Systems in cooperation with the Technical University of Munich and its Chair of Energy Systems.

Unfortunately, the current situation regarding the Covid-19 mutations and the vaccination progress did not provide enough reliability to organize a physical event. Thus, the conference took place in virtual form on October 11, 12 and 13, 2021.
