Considering that the renewable energy offer is representative of the renewable
energy policies in force, the decarbonisation potential, expressed in percentage, provides an indication on how much those policies can impact of the
decarbonisation of industry sectors using fossil fuel-based hydrogen.
The following section provides the results of the decarbonisation potential
assessment, case study by case study. At the end of the section, he results are
consolidated to provide an APAC and regional wide overview of the research
topic.

The Results of the Study Case Australia
6.1.1 The Current Decarbonisation Potential of Australia
The appendix 19 shows the decarbonisation potential under the current renewable energy policy regime in Australia. The steel manufacturing option (b) is not
a viable scenario as that would mean that all the steel manufacturing currently
happening in Australia would be changed to the DRI-EAF route.
The results show that if all the renewable electricity produced in Australia
would be used to produce renewable hydrogen as per scenario (1), their industries
falling under the research scope could be decarbonised to 74%, offsetting 5,55 Mt
of CO 2 .
In the more realistic scenario (2), the decarbonisation potential would be of
4%, with 0,33 Mt of CO 2 offset.
In the scenario (3), using a power-to-gas system for a duration of 2.550 hours
yr -1 would enable a 21% decarbonisation, offsetting 1,61 Mt of CO 2 .
6.1.2 The 2030 Decarbonisation Potential of Australia
The appendix 19 shows the decarbonisation potential with the 2030 targeted
renewable energy capacities set under the current renewable energy policies in
Australia.
The scenario (1) with steel manufacturing option (b) shows that with the current 2030 target of 33 gigawatts hour renewable electricity production, Australia
would be able to entirely decarbonise their industries falling under the research
scope. There would even be a slight excess generation. The CO 2 offset would be
of 15,24 Mt.
