Bi-objective optimal design of Hydrogen and Methane Supply Chains based on Power-to-Gas systems

This paper presents a methodological design framework for Hydrogen and Methane Supply Chains (HMSC) based on Power-to-Gas (PtG) systems. The novelty of the work is twofold, first considering specific demand hydrogen electromobility in addition to required as feedstock produce synthetic methane from methanation process performing bi-objective optimization HMSC provide effective support study deployment scenarios. approach Mixed Integer Linear Programming (MILP) with augmented epsilon-constraint implemented GAMS environment according multi-period (2035–2050) several available energy sources (wind, PV, hydro, national network) production. Carbon dioxide stem mainly methanization gasification processes. objectives be minimized simultaneously are Total Annual Cost greenhouse gas emissions related whole over entire period studied.
