About us - White Paper

The European Conferences on Supercritical CO2 (sCO2) were initiated in Vienna in 2016 by an informal committee which was composed of only  a few people. Just recently, in 2018, a formal conference committee was appointed, including the following members:

Dieter Brillert, Universität Duisburg-Essen, Chair of Turbomachinery (conference chair)
Albannie Cagnac, EDF R&D, Fluid Dynamics, Power Generation and Environment Department
Václav Dostál, Czech Technical University in Prague (local conference organizer)
Otakar Frýbort, Research Centre Řež, Energy Technology Department
Uwe Gampe, Technische Universität Dresden, Chair of Thermal Power Machinery and Plants
Markus Haider, Technical University of Vienna, Institute for Energy Systems and Thermodynamics
Andreas Jäger, Technische Universität Dresden, Chair of Thermal Power Machinery and Plants
Rene Pecnik, Technical University of Delft, Department of Process and Energy
Jörg Starflinger, University of Stuttgart, Institute of Nuclear Technology and Energy Systems (IKE)
Teemu Turunen-Saaresti, LUT University, School of Energy Systems
Andreas Werner, Technical University of Vienna, Institute for Energy Systems and Thermodynamics
Marco Astolfi, Energy Department of Politecnico di Milano

The organisation of the conference is divided into a local organisation team and a general committee team. The local organisation team manages the conference venue, including accommodations and hotel recommendations as well as traveling advices. The team is led by one of the general committee team members. The general committee team, on the other hand, arranges the paper review process, registration, the agenda preparation and manages external contacts and the committee's representation, which also includes the website.
