The Results of the Study Case Taiwan
6.5.1 The Current Decarbonisation Potential of Taiwan
According to the results shown in appendix 23, the current renewable energy offer
would not provide a significant decarbonisation potential. With the scenario (1)
and steel manufacturing option (a), the decarbonisation potential from the entirety
of the renewable electricity generation would be of 34% with a CO 2 offset of
3,26 Mt yr −1 .
With the scenario (2), the use of the curtailed electricity would enable a 2–3%
decarbonisation potential with a 0,26–0,74 Mt yr −1 CO 2 offset.
The economically viable use of power-to-gas systems as per scenario (3) would
allow for an 8–10% decarbonisation potential with a 0,95–2,68 Mt yr −1 CO 2
offset.
Like the other study cases, the option (b) is not viable for assessing the current
decarbonisation potential as this would entail that all the steel is manufactured via
the DRI-EAF route.
6.5.2 The 2025 Decarbonisation Potential of Taiwan
Taiwan has not defined renewable energy targets beyond 2025. However, according to the results obtained in the appendix 23, the planned renewable energy
development targets for 2025 would allow for an excess of decarbonisation
potential with the scenarios (1) and (3).
The most realistic scenario (3) with steel manufacturing option (b) indicates
that a deep decarbonisation of the industry sectors falling in the research scope
is possible. In this scenario, the economically viable use of power-to-gas systems
could achieve an 85% decarbonisation potential, with a CO 2 offset of 28,37 Mt
yr −1 .
With the scenario (2), the decarbonisation potential would be of 23–29% with
a possible CO 2 offset of 2,8–7,83 Mt yr −1 .
6.5.3 The Decarbonisation Potential of Taiwan Using its
Technical Potential of Renewable Energy
Like Japan and South-Korea, the results of appendix 23 show that Taiwan renewable energy technical potential could allow for renewable hydrogen self-sufficiency
