The Green Steel Economic Fairways Mapper

Global steel demand is forecast to grow in the coming decades with continued development across Asia and Africa. Over the same period, the International Energy Agency suggests that the carbon intensity of steel production will need to decrease rapidly to align with projected pathways to net zero emissions by 2050. Balancing these competing priorities is a challenge that could shift global steelmaking business models. With abundant resources of both iron ore and metallurgical coal, Australia has benefited significantly from traditional steelmaking value chains. In the face of potential disruption, how should Australia navigate the challenges and opportunities accompanying the transition to ’green’ steel? How can geoscience help to identify and leverage Australia’s specific advantages? 

The Green Steel Economic Fairways Mapper is a free, online tool that models the costs of hydrogen-based green ironmaking and steelmaking and maps how these costs vary across Australia. Developed through collaboration between Geoscience Australia and Monash University, it represents a novel approach to model multiple interconnected resource facilities. Following the Economic Fairways approach, the Mapper combines large-scale infrastructure and geoscience datasets to provide a high-level, geospatial analysis of the economic viability of hypothetical green steel projects. In doing so it creates a new capability within Australia—filling the void before the detail and expense of feasibility studies—to understand the broad contours of the decarbonization challenge, and to inform early-stage decision making in the pursuit of low-carbon steel. In this seminar, we introduce the Green Steel Economic Fairways Mapper, demonstrate its capabilities, and discuss some of the insights it reveals.
