  • KEPCO Develops SF6 Recycling Device to Combat

    Jul 10, 2019The KEPCO Research Institute has been developing SF6 refining and decomposition technology since 2016. In June, the research center completed the development of SF6 refining equipment. SF6 becomes a solid matter at a temperature of minus 100 degrees Celsius. An SF6 refining device keeps SF6 and emits other gases at this temperature.

    Publisher Summary. In Japan, fossil fuels produce more than 60 % of electricity. Electric power generation emitted roughly 300 million metric tons of CO 2 in the 2000 fiscal year and was the source of approximately one third of CO 2 emissions in Japan. Although the share of electricity generated by nuclear power is increasing, there is still a predominant reliance on fossil fuels for
