Energy system transformations for the long term mitigation target in Japan

Event: 3rd Japanese- German Workshop on Renewable Energies
Date: 17-19 October 2018 (Tokyo, Japan)
Conference Paper

Achieving long term climate mitigation targets for Japan requires deep transformations in the energy system, in particular in the power generation sector. Decarbonization of this sector is unclear due to the uncertain nuclear policy after the 2011 Great East Japan Earthquake. However, many other uncertainties need to be considered, namely the availability of carbon capture and storage (CCS), the cost reductions for renewable energy technologies to be scaled up, the improvement of energy efficiency, and the cost of fossil fuels. This study analyses the transformations in the Japanese energy system to realize 80% emission reduction by 2050, comparing the role of uncertain nuclear power deployment to other key uncertainties by means of a computable general equilibrium (CGE) model.
