Title: Analysis of hydrogen integration into the gas grid of Hamburg by means of gas quality tracking
Authors: Tieu Vo Hoang Hai

Abstract: 
The injection of hydrogen into natural gas distribution networks poses challenges for gas grid operators regarding the correct billing of end customers and safety. In this thesis, two particular aspects of hydrogen integration shall be examined on the gas grid of Hamburg. The first aspect is compliance with the billing rule according to the DVGW technical code G685 when a large amount of hydrogen is admixed. Different measures, focusing on the division of the downstream grids into more suitable calorific value districts, shall be evaluated to address this aspect. The second aspect is compliance with a certain blending limit of hydrogen which is assumed to be 20 % by volume. A methodology shall be developed to ensure this compliance when there is a risk that the limit may be exceeded. To investigate these tasks, various scenarios in which hydrogen is injected at different locations in the grid are examined using gas quality tracking
