Abstract
We introduce the GIS-based optimization tool FlexiGIS-H2, applied to urban areas in both New Zealand and Germany to identify the potential for hydrogen to aid the energy transition within cities. Based merely on open-source datasets, we connect existing urban energy infrastructure, electricity generation and hydrogen production potential and the specific demand of a given city. Land use and building types are used to calculate electricity demand, and available areas are analysed to estimate the potential electricity generation from solar and wind resources, alongside the potential production of green hydrogen. Through cost-minimization, we optimize storage scenarios including batteries and green hydrogen, and solve for the most techno-economic solution to meet electricity and hydrogen demand for urban applications.
In this work, we present the model FlexiGIS-H2 applied to the cities Auckland, Christchurch, Karlsruhe, and Oldenburg, in New Zealand and Germany. Here, we delve into the application of FlexiGIS-H2, our modelling outcomes for different cities, and ongoing developments aimed at supporting decision-making for future energy system planning in urban areas. The resulting hydrogen portfolio and residual energy scenarios, and the optimisation of hydrogen as a flexibility option in urban settings, can be used as inputs to national capacity expansion tools, to provide local detail often lacking at the national level.
