Informationen zum Autor Tilman J. Schildhauer is a Senior Scientist at Paul Scherrer Institut, Switzerland since 2005, working mainly in the field of converting dry biomass to Synthetic Natural Gas (SNG) and electricity. These activities aim at developing sustainable and (energetically and economically) efficient processes based on the analysis of the complete process chain on the one hand and investigation of the fundamentals of the crucial process steps on the other hand. Since 2014, he is also Scientific Coordinator of the Energy Systems Integration platform at Paul Scherrer Institut. Dr. Schildhauer has authored over 60 scientific papers and two book chapters. Serge Biollaz is the Head of the Thermal Process Engineering group at Paul Scherrer Institut since 2000. In 2006/2007 he spent a sabbatical leave at Gas Technology Institute (GTI), Chicago, USA, working on catalytic biomass gasification, hot gas cleaning and integration of biomass/coal gasification with high temperature fuel cells (SOFC). Serge Biollaz co-authored more than 50 scientific papers and is national expert in the IEA Bioenergy, Task 33 Thermal gasification of biomass (since 2003), as well as expert on SNG in the European Biofuels Technology Platform (EBTP), WG2 "Conversion" (since 2009).
