Abstract

In the past few years, a rising interest has been seen in the use of hydrogen. In the long term, the aim is to replace natural gas, as it is one of the most frequently used energy sources in the EU. In the meantime, blending hydrogen into the existing natural gas pipeline network is also thought to be a promising strategy in environmental aspects. One of the most important environmental benefits of switching from natural gas to hydrogen is the decreasing amount of greenhouse gases coming from combustion. This study focuses on the changes that injecting hydrogen into the natural gas grid causes the combustion characteristics of the mentioned substances. This paper investigates whether the combustion characteristics change drastically if the volume of hydrogen varies between 0–100% or not.
