The document explains the tool for optimizing sector coupling hubs. It starts from outlining the structure of the sector coupling hubs and detailing/mathematical modelling of its main parts – gasification, electrolysis and methanation process. The models describe these parts in terms of energy and economical performance such that the optimization tool can weigh between its different parametrizations and planned operations and select the optimal ones.
Basic mathematical modelling principles on which the tool resides on are shown and explained for the full power to gas coupling hub configuration.
