JAPAN ENERGY TRANSITION CHALLENGES
The Oxford Institute for Energy Studies - February 2025 -
Japan’s Energy Transition: The Interplay of Renewables, Gas and Energy Security
Key insights:
• Japan faces substantial challenges in managing its energy trade deficit and high end-user costs while aggressively pursuing decarbonization targets amidst geopolitical tensions. There are significant concerns about Japan's ability to meet its emissions targets, casting doubts on its broader 2050 decarbonization plans.
• The draft 7th Strategic Energy Plan proposes ambitious raised targets for renewable energy, nuclear power, and a reduction in fossil fuel use by 2040, while acknowledging that power demand will rise. However, the plan itself appears to acknowledge the challenges ahead, raising the question of just how realistic and achievable these new targets are.
• While solar power continues to show significant progress, becoming a dominant renewable energy source in Japan, other renewable sources including wind and geothermal are lagging. This slower pace in diversifying the renewable portfolio will make it more difficult for renewables to be the projected dominant component of Japan's energy mix by 2040.
• Despite strategic intention to revitalize nuclear energy alongside renewables, the continued restart of nuclear power plants faces challenges like rising safety costs, delayed approvals and wavering public acceptance, which could make it more difficult to meet targets.
• While Japan remains committed to decarbonizing its energy sector, any shortfalls in the nuclear and renewable sectors will elevate the role of LNG as a means of balancing energy supply security with decarbonization. LNG’s long-term role does however keep Japan reliant on imported energy and thereby reliant on global LNG market dynamics and price volatility.
• The international market conditions and domestic policy shifts highlight the necessity for Japan to maintain a flexible and responsive energy strategy to balance its immediate energy security needs with long-term sustainability and climate commitments. The role of LNG and renewables is critical in the near term, while the future of nuclear power expansion remains uncertain.
