example 1

[0118] The conversion of electric energy into other forms of energy is convenient, easy to use, and easy to transport; but the electric energy itself is ready-to-use, and the electric energy generated is not consumed in time. In the valley stage, some of the electric energy generated by the power plant cannot be consumed in time, and the uncertain power output of these uncertain energy sources has an impact on the power grid. For example, the power generated by wind power fluctuates with the wind speed, which may even cause the power grid to collapse. ; Hereinafter referred to as "garbage power";

Abstract

Energy storage, carbon sequestration and new energy circulation is characterized in that carbon dioxide and water are electrolyzed by utilizing garbage electric energy which cannot be consumed and can be wasted to generate methanol for storage, so as to realize chemical energy storage; carbon dioxide sequestration is realized; when a user needs power supply, an alcohol fuel cell generates power on demand to meet human demands; the environmental requirements of carbon dioxide and methanol storage are simpler, more economical and safer than those of hydrogen storage; and zero emission of carbon is realized. Meanwhile, carbon dioxide generated in other ways and carbon dioxide in air are subjected to carbon sequestration; the method is safer than geological carbon sequestration and has economic benefits. Economical benefits can be achieved for real operation. Carbon dioxide and water are electrolyzed through garbage electric energy to generate methanol, and a closed loop of methanol circulation is achieved. The stored alcohol provides energy which can be used at any time for human beings, and the energy crisis of the human beings is solved. An alkaline electrolyzer, an alkaline bipolar electrolyzer and a solid electrolyte electrolyzer are adopted for implementing energy storage, carbon sequestration and new energy circulation.
