Abstract
Green hydrogen has gained significant global attention in the urge for decarbonisation. With a plethora of hydrogen applications for different sectors, it is crucial to identify and prioritise the most suitable and economical options.
To assess the integration of green hydrogen in cities, we present the open-source, GIS-based model FlexiGIS-H2 applied to model the urban energy system in Christchurch, New Zealand. The tool supports decision-making for future energy system planning. Based on open-source data, the model detects existing urban energy infrastructure for a given city. For future expansion planning, land use and building models are assessed to determine energy demand. Future generation and storage technologies are also investigated, for example by correlating suitable rooftop areas to potential PV installations. By means of cost-minimization, a technology mix to meet current and future energy demand is proposed, leveraging renewable resources and flexibilisation technologies, including hydrogen. FlexiGIS-H2 assesses different energy scenarios, including a reference, a carbon-neutral and a hydrogen scenario, under current and future cost projections.
In this work, FlexiGIS-H2 is applied to the case study of Christchurch, but application to other cities is straightforward. The resulting energy portfolio and residual energy profiles can be used as inputs to national capacity expansion tools, to provide local detail that these tools often lack. Here, we discuss the application of FlexiGIS-H2, our modelling results for Christchurch, and our planned work integrating these results into a country-wide integrated energy system model.
