6.3.4 The Concluding Remarks Regarding the Impact
of Renewable Energy Policies on Japan Industry
Decarbonisation
With the current renewable energy 2030 targets, the decarbonisation potential of
the industry sectors falling under the research scope is limited.
However, Japan has the renewable energy technical potential to be selfsufficient in renewable hydrogen. The estimated 3,58 Mt yr −1 of renewable
hydrogen demand at 2030 could be covered in all scenarios. The scenario (3) indicates that Japan could use economically viable power-to-gas systems to cover the
renewable hydrogen demand for the ammonia, methanol, oil refineries and steel
manufacturing sectors and still having up to 17 Mt yr −1 of renewable hydrogen
available for other applications.

The Results of the Study case South-Korea
6.4.1 The Current Decarbonisation Potential of South-Korea
According to the results shown in appendix 22, the renewable energy offer of
South-Korea is limited. According to scenario (1) with steel manufacturing option
(a), all the renewable electricity of South-Korea would only allow for a 6%
decarbonisation potential with 1,72 Mt yr −1 CO 2 offset.
The scenarios (2) and (3) are providing negligible decarbonisation potential.
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.
6.4.2 The 2030 Decarbonisation Potential of South-Korea
The appendix 22 shows that the planned renewable energy development targets
for 2030 are not considering the production of renewable hydrogen. While SouthKorea plans to use 30% of renewable hydrogen in 2040 (Arabzadeh, Pilpola, and
Lund 2019), using the entirety of the renewable energy generation would enable
a decarbonisation of 20–23% with a limited CO 2 offset of 6,27–20,38 Mt yr −1 .
Like with the current renewable energy offer, the 2030 renewable energy targets with the scenarios (2) and (3) would allow for a very limited decarbonisation
potential of 2–7% with a CO 2 offset of 0,5–5,91 Mt yr −1 .
