Fig. 2: Map of potential hydrogen generation zones selected for the analysis.

The maps show the considered renewable energy zones (potential sites for green electrolysis projects), existing electricity transmission lines, roads, railways, gas and oil pipelines and port infrastructure. The location of the NEM connected REZs were adopted from the AEMO ISP, the rest of the locations for WA and NT were drawn to approximation (region with same solar and wind traces). The data for the infrastructure (road, rail, electricity transmission lines, natural gas/oil pipelines and port locations) and the map of Australia were adopted from data made available by Commonwealth of Australia (Geoscience Australia) under Creative Commons Attribution 4.0 International Licence26.
