6.2 The Results of the study case China
91
With the scenario (2) using the curtailed renewable electricity, the decarbonisation potential could range between 9–12% and corresponding to a CO 2 offset
ranging between 121,73–205,71 Mt yr −1 .
According to scenario (3), the utilization of a power-to-gas system for a
minimum economically viable period, would enable a decarbonisation potential
ranging from 26–35% with a CO 2 offset ranging between 344,70–582,50 Mt yr −1 .
6.2.3 The Decarbonisation Potential of China Using its
Technical Potential of Renewable Energy
The appendix 20 shows that China solar PV and wind power technical potential
would enable a complete decarbonisation of the industry sectors falling under the
research scope for scenarios (1) and (3). In the scenario (3), if China would have
shifted the manufacturing process to a full DRI-EAF route as per option (b), this
would enable a CO 2 offset of 2.201,30 Mt yr −1 .
Only using the curtailed renewable electricity generation according to scenario
(2) would enable a decarbonisation potential ranging between 43–57% for a CO 2
offset ranging between 550,66–945,77 Mt yr −1 .
6.2.4 The Concluding Remarks Regarding the Impact
of Renewable Energy Policies on China Industry
Decarbonisation
China renewable electricity generation targets at 2030 is estimated to be of
3.297 terawatts hour. This is a hundred-fold the Australia 2030 renewable electricity generation targets. However, given the scale of the hydrogen demand
(65,09 Mt yr −1 ), this will only allow a partial decarbonisation potential of the
industry sectors falling under the research scope.
The production of renewable electricity to China technical potential and the
use of power-to-gas systems for a minimum economical duration would enable a
full decarbonisation of the industry sectors mentioned above.
