While initial trials indicate that existing Australian gas distribution networks should be able to accept the hydrogen blend, the Australian Gas Infrastructure Group has argued that the gradual replacement of existing cast iron distribution pipelines with high-density polyethylene tubes is already widespread across Australia. With regard to safety, the Working Group notes that the use of hydrogen as fuel for on-road vehicles is already possible thanks to existing traffic regulations, as well as the movement and refuelling of hydrogen-powered vehicles. This includes requiring hydrogen and battery electric vehicles to have an identification tag so that first responders can take the necessary precautions in the event of an emergency response. But new skills will be needed, which will be strengthened in terms of maintenance and maintenance of the FCEV. During a transitional period, the working group suggests that there could be a limited capacity exchange period: for example. B, the mechanics of hydrogen between national bus fleet operators and private vehicle owners. 60 The planning and construction phase of the project is expected to be completed in December 2020, with operations from January 2021 to December 2023. As previously announced, Hazer plans to sell renewable hydrogen for industrial applications and explores graphite markets, including soot, activated charcoal and battery anode applications. The working group is aware that the gas sector is very interested in the use of hydrogen on the Australian gas network, with the document addressing the various components of these networks37.
The working group believes that hydrogen can support electrical systems in three ways: the production of hydrogen from renewable energy is currently more expensive than processes based on fossil fuels. , although the cost of renewable energy is expected to continue to fall.5 hydrogen production; There is also its transport, storage and handling, from producers to end consumer.6 Now, HyP SA has only to start producing green hydrogen to launch a whole new chain of carbon-free gas opportunities and wind and solar resources that make it possible.
