Introduction of Liquid Nitrogen

As a new energy medium, liquid nitrogen can not only be used for power generation, automobile engines, data center heat dissipation, fossil fuel carbon reduction, superconducting power transmission, but also can be widely used in national defense, scientific research, clinical medicine and other fields, thus forming An integrated ecology of energy saving, energy storage, production capacity and energy transmission.

Xu Yingqiang, a researcher at the Institute of Semiconductors of the Chinese Academy of Sciences, pointed out that while the liquid nitrogen ecosystem realizes energy storage in unlimited geographical conditions, it drives the infrared focal plane, low-temperature circuits, supercomputing chips, semiconductor large-scale production equipment, medical technology, new energy vehicles, The development of quantum computing and other fields has expanded the profit model, established multiple income methods, realized the large-scale development of the energy storage industry, and provided a new way of thinking for the construction of my country's liquid nitrogen new energy system. system is important.

Cryogenic energy storage solution

Development requires energy consumption, but at the same time, it is also necessary to achieve carbon peaking and carbon neutrality, which puts more stringent requirements on my country's energy consumption. A currently technically mature solution is low-temperature liquid nitrogen energy storage for power generation. Its technical principle is as follows:

First, use renewable wind and solar energy to cool the air to -196℃, liquefy nitrogen, and store it in a cryogenic tank in liquid form;

Second, the liquid nitrogen is vaporized to restore the gas form, and the energy released in this process is used to drive the turbine to generate stable electricity;

Third, the generated electric energy can be transported outward through liquid nitrogen superconducting transmission lines, further reducing electric energy loss

Liquid nitrogen pressure sensor used in cryogenic energy storage

The PPM-T330D liquid nitrogen pressure sensor is a cryogenic pressure transducer that can work normally at a low temperature of -196°C. Special processing and temperature-resistant materials, strong resistance to hydrogen embrittlement and corrosion. At the same time, PPM-T330D cryogenic pressure transducer has the characteristics of small size, high measurement accuracy, high dynamic response frequency and long working life. It has been used in many liquid nitrogen cryogenic energy storage projects, and is widely used in cryogenic scientific experiments, liquid energy storage systems, aerospace and naval cryogenic storage tanks. The cryogenic pressure sensor has reliable performance and long service life. For product parameters, please refer to the PPM-T330D liquid nitrogen pressure sensor product documentation.
