Episode notes
Shift from Emissions to Security
- Japan's 2021 energy plan focused exclusively on reducing greenhouse gas emissions.
- After recent crises, the 2024 plan balances emission goals with elevated energy security concerns.
LNG's Growing Role in Japan
- Japan sees thermopower generation as essential, expecting 30-40% power from it by 2040.
- LNG will replace coal to lower carbon emissions in power and industry heat generation.
Japan's Dual LNG Demand Scenarios
- Japan anticipates LNG imports between 54 to 60 million tons per year by 2040 on the carbon neutral path.
- Plan B allows as much as 74 million tons if renewables and technologies lag, showing flexible energy planning.
