Japan intends to adjust the proportion of electric energy

    Regarding the proportion of various electric energy in the total Solar System Electricity Homes power generation in 2050, the Ministry of Economy, Trade and Industry of Japan proposed at an expert meeting on the 21st that renewable energy accounted for 50 to 60% and hydrogen and ammonia accounted for 10% of the total power generation. The remaining 30-40% will be maintained by nuclear power plants and thermal power plants. In order to achieve the goal of “essentially zero emissions of greenhouse gases by 2050” proposed by Japanese Prime Minister Yoshihide Suga, the Ministry of Economy, Trade and Industry plans to incorporate this plan into the implementation plan of the Japanese government’s green growth strategy announced on the 25th.

    It is reported that about 40% of greenhouse gas emissions in Japan come from the power generation sector. In the future, the Ministry of Economy, Trade and Industry will use the reference values ​​in the plan to conduct analysis through various data such as economic efficiency and supply stability. The Ministry of Economy, Trade and Industry believes that “the reference value is not set as a government goal, but one of the benchmarks and options for intensified discussion in the future.” However, this measure may be related to the addition of new nuclear power plants and the reconstruction of nuclear power plants. Will cause controversy.

    According to reports, after the accident at the Tokyo Electric Power Fukushima Daiichi Nuclear Power Plant, a number of domestic nuclear power plants have been scrapped one after another, and there are currently 36 nuclear power plants (including 3 under construction). If the operating time of all nuclear power plants is 40 years stipulated by law, then by 2050, there will only be three nuclear power plants under construction in Japan. Even if all nuclear power plants are extended for another 20 years, the number of nuclear power plants will be reduced to 23 by 2050. In the expert meeting, many people recognized the use of atomic energy, "In order to achieve the goal of substantially zero carbon dioxide emissions, it is important to make full use of thermal power and atomic energy", and "new nuclear power plants should be added". On the other hand, some people have also pointed out "To what extent has the credibility of nuclear power plants been restored?" "Is the economic efficiency of nuclear power plants really high? They question this."

    In addition, in the implementation plan of the Japanese government's green growth strategy, atomic energy is positioned as one of 15 important areas. In addition to participating in the international cooperation projects of small nuclear power plants (SMR) and empirical tests of high-temperature gas furnaces, the Japanese government has also proposed that it will effectively promote the International Thermonuclear Experimental Reactor (ITER) project.
