Abstract
In this contribution a laser-based photometer detecting inelastic scattered light is presented capable of measuring the calorific value of natural gas and the H2 content in combination with an acoustic resonance analyzer to measure gas density. It is shown that the relevant parameters calorific value and gas density can be measured within several seconds with an uncertainty that is required for the gas turbine application using high hydrogen/ natural gas blends. A hydrogen-based economy shows us further applications for this exciting combination of gas sensing principles.

During his Sensor Technology (Electrical Engineering) studies at the University of Applied Science in Karlsruhe, Konstantin Harr worked as a working student since 2016 in the R&D laboratory for gas analytics at Siemens AG in Karlsruhe. 2021 he absolved his M.Sc. in Sensor Technology. Now he is doing his PhD in the R&D laboratory at Siemens AG in cooperation with the Karlsruhe Institute of Technology (KIT). He did his M.Sc. in Sensor Technology (Electrical Engineering) in 2021 at the University of Applied Science in Karlsruhe. During his PhD he is investigating the composition of gas mixtures based on the Raman effect. In his recent work, together with Dr. Camiel Heffels, he developed a prototype of a gas analyzer, which can measure the calorific value (and Wobbe index) of natural gas in a matter of seconds.
