Abstract
To analyse the viability of hydrogen integration in natural gas infras-
tructure, we present an optimization tool that evaluates hydrogen trans-
port through either admixing natural gas or repurposing pipelines for
pure hydrogen pipelines. The model is formulated as a mixed-integer
non-linear optimization problem that brings together pooling and flow-
pressure formulations. The model is implemented as an extension to
the open-source EnergyModelsX (EMX) framework and applied to a
case study from the SHIMMER project.
