Have you ever seen a giant "charging treasure" with two hours of charging and 20,000 degrees of power deposit? On August 22, Dongfang Electric Group Oriental Electric Turbine Co., Ltd., located in Deyang City, Sichuan Province, stands a blue and white "hill". At the foot of the "mountain", a row of factories, pipelines, and tanks are neatly arranged to form together to form together to form together to form together to form together to form together to form together to form together to form together to form together to form together to form together to form together to form together to form together to form together to form together to form together to form together to compose together The "charging treasure" covers an area of ​​about two and a half football fields, which is the world's first carbon dioxide+flywheel energy storage demonstration project.

Carbon dioxide+flywheel energy storage demonstration project

Energy storage is to convert the remaining electricity into other energy to store it in the low valley period. At the peak period of power consumption, the energy is re -converted into electrical energy. Energy storage projects can not only make up for the shortcomings of clean energy unstable, but also provide electricity during the peak of electricity consumption, and navigate the stable operation of the power grid, the normal use of electricity protection in production and life.

The huge "charging treasure" built by the Oriental Steam turbine uses 250,000 cubic meters of carbon dioxide as a circulating work quality for charging and discharge, which can save 20,000 degrees of electricity in two hours, and it is enough for more than 60 families to use it for 1 month. The entire "charging and discharge" process will not use fossil fuels, nor does it produce solid waste, zero carbon emissions.

It is reported that the flywheel in this "charging treasure" can realize the mutual conversion of kinetic energy and electrical energy, green and environmentally friendly, and the response speed is extremely fast, reaching milliseconds.

At the same time, this "charging treasure" combined with the characteristics of large -scale carbon dioxide energy storage time, and the fast -moving response speed of the flywheel storage can effectively smooth the volatility of the grid, solve intermittent problems, and realize the safe operation of the power grid. Compared with other energy storage forms, there is no electrochemical component. Its construction cycle is less than 2 years. After completion, it can be used continuously for 30 years, and the efficiency can be maintained at more than 60%. At the same time, the standardized module design can be constructed according to the needs.

In a few days, the project will appear as one of the eight major demonstration application scenarios of the World Clean Energy Equipment Conference.
