The article discusses insights from Nobuo Tanaka, Executive Director Emeritus of the International Energy Agency, regarding Japan's Seventh Strategic Energy Plan and the upcoming Japan Energy Summit and Exhibition in Tokyo. The plan focuses on energy security in light of global uncertainties, with a particular emphasis on LNG investments and alternative scenarios to achieve net zero emissions by 2050. It highlights the importance of nuclear energy, proposing a significant increase in nuclear power generation by 2040 and exploring the potential of small modular reactors. The plan aims to strike a balance between sustainability, efficiency, and energy security by incorporating renewables, clean thermal power sources like hydrogen and ammonia, and carbon capture and storage. The Japan Energy Summit and Exhibition, chaired by Tanaka, will address critical energy issues such as natural gas, hydrogen, renewables, and nuclear power, promoting global collaboration to redefine the future of energy.
