Abstract

Abstract. This article presents the framework of a mathematical formulation for modelling and evaluating natural gas pipeline networks under hydrogen injection. The model development is based on gas transport through pipelines and compressors which compensate for the pressure drops by implying mainly the mass and momentum balances on the basic elements of the network. The model was initially implemented for natural gas transport and the principle of extension for hydrogen–natural gas mixtures is presented. The optimization procedure has been formulated by means of a nonlinear technique within the General Algebraic Modelling System (GAMS) environment. This work deals with the adaptation of the current transmission networks of natural gas to the transport of hydrogen–natural gas mixtures. The objective function is the amount of hydrogen for a given transmission power. Typical quantitative results are presented, showing that the maximum fraction of hydrogen that can be added to natural gas is around 6 mass percent for the studied example. According to this study, an adaptation of the current networks of transmission of natural gas to the transport of hydrogen seems to be possible with low contents of hydrogen. This paper shows that the design of large new hydrogen infrastructures can be seen as more challenging and is expected to necessitate substantial additional effort to attain wide deployment under safety conditions.
