新型发电领域的“超级跑车”来了！发电效率提升的秘密藏在这里→

Core Viewpoint - Supercritical carbon dioxide (sCO2) power generation is recognized as a strategic frontier technology in the energy sector by the U.S. Department of Energy and has been under research in China since 2009 [1] Group 1: Technology Overview - The sCO2 power generation process involves raising carbon dioxide to a supercritical state at approximately 31 degrees Celsius and 74 atmospheres of pressure, which enhances efficiency by 5 to 8 percentage points compared to traditional steam [3] - In its supercritical state, carbon dioxide has a high density, allowing it to store more energy, and its low viscosity reduces flow resistance, enabling a simpler and faster response in the power generation process [5] - The sCO2 power generation consists of four steps: compression, heating, expansion, and cooling, which collectively create a high-temperature, high-pressure environment to drive a turbine for electricity generation [11] Group 2: Industry Impact - The adoption of sCO2 technology is expected to revolutionize power generation models, equipment forms, operational modes, and overall efficiency, leading to disruptive changes in power plant processes [13] - The unique working advantages of carbon dioxide make it a preferred choice among various working fluids, as it is humorously referred to as the "chosen one" for its superior performance [7]
