China’s first supercritical CO2 cycle power generation unit is put into operation and thermal power generation meets important revolutionary technologies
[Securities Times] according to China Huaneng’s official news, recently, China Huaneng Group Co., Ltd. independently developed the world’s highest parameters The maximum capacity supercritical carbon dioxide (CO2) cycle power generation test unit successfully completed 72 hour trial operation in Huaneng Xi’an Thermal Engineering Institute and was officially put into operation. The unit boosted the collected carbon dioxide to 20MPa through the compressor (MPA) above, and then heated to 600 ℃ by the heat source to form high-temperature and high-pressure gas, which drives the gas turbine to rotate, converts the heat energy into mechanical energy, and then drives the generator to generate electricity.
Comments: experts said that the successful operation of this unit has verified the feasibility of industrial operation of supercritical carbon dioxide cycle power generation technology, and is expected to completely change the power generation mode of traditional thermal power generation technology with steam as the mainstream working medium for more than 140 years. Supercritical carbon dioxide cycle power generation technology is an important revolutionary technology in the field of thermal power generation, and it is also an effective way to save energy and reduce carbon in China’s power generation field. In the future, supercritical carbon dioxide cycle power generation technology can also be further applied to thermal power, high-efficiency photothermal, nuclear power, energy storage and other fields. It has a very broad prospect and plays a positive role in promoting China’s construction of a new power system with new energy as the main body and realizing the goal of “double carbon”.
Shouhang High-Tech Energy Co.Ltd(002665) (002665): the work related to the application of supercritical carbon dioxide power generation technology developed by the company to photothermal power generation and ship field is being actively promoted. This technology can be applied to photothermal power generation system, energy storage power generation system, ship power system, mobile power supply and other military fields.
Jin Tong Ling Technology Group Co.Ltd(300091) (300091): the company, Thermal Power Research Institute of Xi’an Jiaotong University and nuclear energy research institute are jointly developing supercritical carbon dioxide expander and new products related to nuclear energy.
