Prof. Johannes Kiefer
University of Bremen, Germany
Johannes Kiefer is Chair Professor and Head of the engineering thermodynamics division at the University of Bremen, Germany. In addition, he is the Dean of the faculty of production engineering at the University of Bremen. He earned his chemical engineering degree and his PhD from the University of Erlangen-Nuremberg. From 2010 to 2014 he was a lecturer and senior lecturer at the University of Aberdeen before he moved to Bremen. He was visiting researcher at renowned institutions including the division of combustion physics at the University of Lund, Sweden and the Combustion Research Facility of the Sandia National Labs Livermore, US. His research interests are the areas of developing and applying spectroscopic techniques for the characterization of advanced materials and processes including combustion. Johannes has received a number of prizes including the Combustion Institute British Section's Hinshelwood Prize 2012 and the 2010 distinguished paper award on diagnostics at the 33rd International Symposium on Combustion.
Title: Hydrogen sensing – Methods for the analysis of fuels and reacting flows
Abstract: Hydrogen is considered as an important energy carrier of the future. Its widespread use calls for the development of analytical methods that enable the control of the quality of hydrogen-based fuels. Furthermore, when hydrogen is part of reacting flows like in a combustion environment, a fuel cell, or in a chemical hydrogen storage, methods for hydrogen detection and sensing are required. The lecture will introduce advanced methods for hydrogen analysis and their applications. The focus will be on non-contact techniques based on optical phenomena.
