Prospective hydrogen production regions of Australia - geospatial inputs

There is significant interest in Australia, both federally and at the state level, to develop a hydrogen production industry. Australia’s Chief Scientist, Alan Finkel, recently prepared a briefing paper for the COAG Energy Council outlining a road map for hydrogen. It identifies hydrogen has the potential to be a significant source of export revenue for Australia in future years, assist with decarbonising Australia’s economy and could establish Australia as a leader in low emission fuel production. As part of the ongoing investigations into the hydrogen production potential of Australia, Geoscience Australia has been commissioned by the Department of Industry, Innovation and Science to develop heat maps that show areas with high potential for future hydrogen production. The study is technology agnostic, in that it considers hydrogen production via electrolysis using renewable energy sources and also fossil fuel hydrogen coupled with carbon capture and storage (CCS). The heat maps presented in this work are synthesized from the key individual national-scale datasets that are relevant for hydrogen production. In the case of hydrogen from electrolysis, renewable energy potential and the availability of water are the most important factors, with various infrastructural considerations playing a secondary role. In the case of fossil fuel hydrogen, proximity to gas and coal resources, water and availability of carbon storage sites are the important parameters that control the heat maps. In this report we present 5 different heat map scenarios, reflecting different assumptions in the geospatial analysis and also reflecting to some degree the different projected timeframes for hydrogen production. The first three scenarios pertain to renewable energy and hydrogen produced by electrolysis. Differences between the three scenarios depend on whether hydrogen is produced near the coastal areas, where infrastructure and water are not issues or whether hydrogen can be produced in inland areas provided water does become a constraining factor. Assumptions regarding the proximity of a currently connected electrical grid to transport renewable energy also play a large role in the different scenarios. The final two scenarios focus on the potential for fossil fuel hydrogen, coupled with CCS, with the difference between the two scenarios being related to the timeframes for readiness for both fossil fuel production and availability of CO2 storage resources.This dataset includes the raster inputs used for the five scenarios as part of the Prospective hydrogen production regions of Australia report.
