“…The "price-taker" assumption in this study is based on the expectation that increasing wind and solar electricity production will be deployed onto the grid [1]. In addition, it should be noted that there might be other revenue streams for flexible steel manufacturing, such as providing Frequency Control Ancillary Services [8], participating in the wholesale demand response market [2], etc. These considerations will be further scrutinised in later studies.…”

Green steel – produced using hydrogen and electricity from renewable en-ergy sources – provides both the means to decarbonize steel manufacturing,and a way to facilitate growth of the international hydrogen industry. Aus-tralia, with its abundant renewable resources and ample iron-ore deposits,is in an excellent position to participate in this opportunity. We highlightthe synergies between the Australian iron-ore industry and the production ofgreen-hydrogen from renewable energy sources. We identify high-potentialareas for green steel production by cross-referencing regions of current andfuture iron-ore extraction against areas of high economic potential for hy-drogen production. From these, we select two regions, the Pilbara regionof North-Western Australia and the Eyre Peninsula in South Australia, formore detailed case studies.The analysis highlights the advantages of well-optimised generation mix(in terms of wind, solar, battery, grid-connection and salt cavern storage, etc.)in decreasing storage requirements and the resulting production costs. Wealso demonstrate that green steel production costs could be reduced furtherif the system could use grid electricity to balance onsite renewable power byparticipating in the electricity spot market and operating flexibly.

“…Some other studies focused mainly on the use of electrolysers as a variable load to help regulate grid frequency, [43]. A dynamic model of the electrolysers stack, power-electronics interface, and downstream hydrogen process operational constraints is modelled to study the Fast Frequency Response capability of the system, [44]. As said before, Fuel Cells can also help regulate grid frequency.…”

Nowadays, the electric system is evolving towards a paradigm shift, with a constantly higher penetration of renewable generation, as well as the electrification of the transport and different industry sectors. This new scenario requires flexibility services to be provided to transmission and distribution grids, to allow their safe and reliable operation. From amongst the various options currently investigated, hydrogen technologies are demonstrating great potential in terms of lower energy costs for consumers/prosumers, lower emissions, and better levels of quality and security of supply. This paper provides a review of the latest state-of-the-art flexibility services that hydrogen-based technologies can provide to both DSOs and end-users. This review considers contributions from both academia and industry.

“…The feeder under study is then integrated into a modified 14-generator national electricity market (NEM) dynamic model [29] with 50% renewables, as from the 2030 stepchange scenario in Australia [30][31], to simulate potential frequency/voltage dynamics and multiple simultaneous responses. The system contingency is the largest generation trip, with the capacity of 667 MW, at t=0.4s.…”
