Today, renewable energy can be stored as hydrogen thanks to technology.
Further, natural gas networks can be used to transport and end-use hydrogen without building
special infrastructure. However, changes in the thermos physical properties of the mixture of
hydrogen and NG can affect the operation of measuring devices, accessories and final equipment.
Therefore, in this paper, we study the effect of hydrogen addition on the thermophysical
properties of SGs from gas fields of various compositions. According to calculations, the
maximum allowable concentration of hydrogen is 10%. The study of the most important
characteristics of the mixture was carried out, and it was found that the injection of hydrogen
into SG increases the upper and lower ignition limits and the compressibility coefficient, as well as
lower and higher heating values, lower and higher Wobbe indices, and the relative density
decreases with increasing hydrogen concentration.
