Australian iron ore is predominantly exported and used for steelmaking internationally. However, steelmaking is an energy- and carbon-intensive heavy industry, and its electrification in the coming decades will likely disrupt the existing iron ore–steel value chains. Green steel—produced using hydrogen and electricity from renewable energy sources—presents both opportunities and challenges for Australia. Indeed, with abundant renewable energy potential and iron-ore resources, Australia could lead this global transformation. Here, we examine the interrelationships between the Australian iron-ore industry, the production of green-hydrogen from renewable energy sources, and an emergent green steelmaking process. In particular, we undertake detailed case studies to estimate current green steel production costs within two regions; the Pilbara Craton in Western Australia and the Eyre Peninsula in South Australia. While existing technology is not well suited to Australian hematite ores, our analysis highlights the site-specific competitiveness of small-scale, magnetite-fed, off-grid operations. The results underscore the advantages of a well-optimised system in decreasing hydrogen and energy storage requirements, and decreasing production costs. While our results also suggest that grid-connected projects could reduce costs through flexible operation, more work is required to understand the limitations of these conclusions. The results underscore the need to develop technologies to utilise hematite ores in green steelmaking, but also highlight the opportunity for this emerging industry to commercialise Australia’s magnetite resources. <b>Citation: </b>Wang C., Walsh S.

Final report on the backgrounds, collaboration structure, methods, and findings from the EIRAPSI project

Knowledge of the nature of buildings within CBD areas is fundamental to a broad range of decision making processes, including planning, emergency management and the mitigation of the impact of natural hazards. To support these activities, Geoscience Australia has developed a building information system called the National Exposure Information System (NEXIS) which provides information on buildings across Australia. Most of the building level information in NEXIS is statistically derived, but efforts are being made to include more detailed information on the nature of individual buildings, particularly in CBD areas. This is being achieved in Brisbane through field survey work.

Knowledge of the nature of buildings within business precincts is fundamental to a broad range of decision making processes, including planning, emergency management and the mitigation of the impact of natural hazards. To support these activities, Geoscience Australia has developed a building information system called the National Exposure Information System (NEXIS) which provides information on buildings across Australia. Most of the building level information in NEXIS is statistically derived, but efforts are being made to include more detailed information on the nature of individual buildings, particularly in business districts. This is being achieved in North Sydney through field survey work.

People, homes, businesses and infrastructure have been severely impacted by the recent flooding in Tweed Shire. Information is needed on the nature of these impacts to assess losses, assess community recovery and contribute to the development of strategies to reduce risk in the future. To collect this information a survey team has been established to gather data on the impact on buildings and businesses. The survey team is being led by Geoscience Australia, the national agency for geoscience research and spatial information, in collaboration with RMIT University and the Tweed Shire Council.

This brochure describes the work undertaken at Geoscience Australia (GA) to develop a blast loss estimation capability for the Australian Reinsurance Pool Corporation. This brochure was developed to accompany a GA record on the same subject. (<a href="http://dx.doi.org/10.11636/Record.2016.022">eCat #101902</a>) Geoscience Australia has developed a modelling capability to estimate the potential impact of terrorist blasts in Australian central business districts (CBDs). With this information, the Australian Government is now able to more reliably estimate insured loss on behalf of the Australian Reinsurance Pool Corporation (APRC). Insured loss is determined based on impact to buildings, contents and business interruption. This capability can now provide blast loss estimates to ARPC in a single business day for the Sydney, Melbourne, Adelaide and Brisbane CBDs. This capability is still in development for the Perth CBD and is expected to be operational by the end of 2016. This blast modelling capability allows ARPC to understand their financial exposure to a range of blast scenarios and assists them to ensure appropriate levels of reinsurance are held to respond to a terrorist incident. Should a terrorist incident occur, loss estimates can be continually reassessed as intelligence from the field is incorporated. Furthermore, the capability provides the ability to assess expected losses across CBDs through simulating many blast locations.
