TOYO TANSO CO., LTD.(Chairman, President and CEO: Naotaka Kondo, hereafter "the Company") has been selected by a major Japanese renewable energy company, a maintenance company, and others to use the carbon brush developed by the Company for wind power generation.

1. Background of adoption
In response to the global trend toward decarbonization, the Japanese government has declared that it will reduce greenhouse gas emissions to virtually zero by 2050, and has set a target of increasing the ratio of renewable energy to 36-38% by FY2030, about double the FY2019 level. In addition, the Ministry of Economy, Trade and Industry (METI) hopes to raise the domestic procurement ratio of components for offshore wind power generation to 60% by 2040. In addition, the rising cost of thermal power generation due to recent fuel price hikes is drawing more and more attention to wind power and other renewable energies. Against the backdrop of these developments, we have conducted tests using our carbon brushes for wind turbine generators on actual wind turbine generators by wind power generators and maintenance companies, and the results have proven positive.

2. key points for adoption
Carbon brushes are used in wind turbine generators and are consumable parts that stably and intermittently supply electricity while sliding against the rotating body. We have continued to develop carbon brushes with emphasis on not only enhancing their durability but also reducing damage to the slip rings that are the counterpart material. As a result, we have succeeded in developing a carbon brush that is highly durable and significantly reduces damage to the slip ring.
