Abstract

Assessing the Impact of Natural Gas and Hydrogen Blending in Integrated Energy System Modeling, submitted to the IEEE GM 2023
Abstract:
This paper assesses the impact of natural gas and hydrogen blending in integrated energy system modeling based on a novel blended transport problem. The proposed formulation ensures that natural gas and hydrogen flow in the same direction and compliance with the maximum hydrogen blending rate, which cannot be guaranteed by a standard transport problem. Our case study shows that the gas flow formulation - and blending in particular - strongly influences investment decisions in the power, natural gas, and hydrogen sectors, which can ultimately lead to suboptimal infrastructure planning (represented in the model as ”regret” in the form of non-supplied hydrogen).
