Japan is the sixth largest greenhouse gas emitter in 2016 and plays an important role to attain long-term climate goals of Paris Agreement. One key policy issues Japan's energy environmental arena system transition achieve 80% emissions reduction 2050, a current goal set 2016. To contribute ongoing debate, this paper focuses on energy-related CO2 analyzes such decarbonization scenarios that are consistent with government goals. We employ six energy-economic integrated assessment models...
In June, 2019, Japan submitted its mid-century strategy to the United Nations Framework Convention on Climate Change and pledged 80% emissions cuts by 2050. The has not gone through a systematic analysis, however. present study, Stanford Energy Modeling Forum (EMF) 35 Model Intercomparison project (JMIP), employs five energy-economic integrated assessment models evaluate nationally determined contribution of Japan. EMF JMIP conducts suite sensitivity analyses dimensions including...
Energy-intensive industries are difficult to decarbonize. They present a major challenge the emerging countries that currently in midst of rapid industrialization and urbanization. This is also applicable Japan, developed economy, which retains large presence heavy compared other economies. In this paper, results obtained from four energy-economic integrated assessment models were utilized explore climate mitigation scenarios Japan's by 2050. The reveal that: (i) share emissions may increase...
Abstract The Japanese power system has unique characteristics with regard to variable renewable energies (VREs), such as higher costs, lower potentials, and less flexibility the grid connection compared other major greenhouse-gas-emitting countries. We analyzed role of (REs) in future sector using results from model intercomparison project Energy Modeling Forum (EMF) 35 Japan Model Intercomparison Project (JMIP) varying emission reduction targets key technological conditions across...
Abstract We study Japan’s net-zero emissions target by 2050 in a multi-model framework, focusing on residual and carbon dioxide removal (CDR). Four energy-economic integrated assessment models show similar but stronger strategies for the target, compared to previous, low-carbon policy (80% reduction). Results indicate that around 90% (inter-model median) of current are reduced through abatement, including improved energy efficiency cleaner electricity fuels. Models deploy new options such as...
Abstract Japan’s long-term strategy submitted to the United Nations Framework Convention on Climate Change emphasizes importance of improving electrification rates reducing GHG emissions. Using five models participating in Energy Modeling Forum 35 Japan Model Intercomparison project (JMIP), we focused demand-side decarbonization and analyzed final energy composition required achieve 80% reductions GHGs by 2050 Japan. The model results show that electricity share use (electrification rate)...
The mass introduction of variable renewable energies, including wind and solar photovoltaic, leads to additional costs caused by the intermittency. Many recent studies have addressed these “integration costs,” proposed novel metrics that replace traditional metric known as levelized cost electricity (LCOE). However, policy relevance those remains unclear. In this study, author investigates re-defines concept system LCOE, referring prior studies, proposes concrete methods estimate them....
Abstract This study investigated cost‐effective energy strategies for realizing net zero CO 2 emissions in Japan by 2050, employing an system optimization model with hourly electricity balances. The detailed temporal resolution enables the to capture intermittency of variable renewable (VRE) and costs integration measures. Siting constraints on VRE, such as prohibiting solar PV onshore wind developments forests offshore inside fishery rights areas, are incorporated reflect environmental...
