With the increasing problem of global climate change and environmental pollution, the new energy industry has been highly valued by governments around the world. The Chinese government has put forward the goal of “carbon peak and carbon neutrality”, which provides a broad market space for the development of the new energy industry. In the field of new energy, valves, as key supporting equipment, play a pivotal role.
01The rise of the new energy industry and the demand for valves
With the global emphasis on environmental protection and sustainable development, the new energy industry has gradually emerged and become an important engine to promote the green transformation of the economy. New energy mainly includes solar energy, wind energy, hydrogen energy, biomass energy, etc., and the development and utilization of these energy sources are inseparable from efficient and reliable equipment support. As an important part of the fluid control system, valves play a vital role in a wide range of applications in the field of new energy, from raw material handling to finished product production, to transportation and storage.
02Application of valves in the field of new energy
Chemical delivery systems for the solar photovoltaic industry: In the manufacturing process of solar panels, a variety of strong acids (such as hydrofluoric acid), strong alkalis, and other chemicals are used to clean silicon wafers or make battery layers. High-performance valves, such as PFA diaphragm valves, are able to withstand the corrosion of these chemicals while ensuring that the purity of the fluid is not compromised, improving the manufacturing quality and efficiency of the panels. Wet process control: In wet processes, such as etching, deposition, or cleaning, valves can precisely control the flow of chemicals to ensure process consistency and reliability.
Electrolyte treatment in lithium-ion battery manufacturing: Electrolytes for lithium-ion batteries often contain lithium salts and organic solvents, which can corrode conventional valves. Valves made of special materials and designed, such as PFA diaphragm valves, can safely handle these chemicals, ensuring the quality of the electrolyte and the performance of the battery. Battery slurry delivery: In the battery manufacturing process, the slurry of the cathode and anode materials needs to be accurately metered and conveyed, and the valve can provide contamination-free and residue-free fluid control, avoiding cross-contamination of materials, and playing an important role in the consistency and safety of the battery.
Hydrogen refueling station in the field of hydrogen energy: Hydrogen refueling station is an important infrastructure for the development of hydrogen energy vehicles, and valves are used in hydrogen refueling stations to control the filling, storage and transportation of hydrogen. For example, high-pressure valves are able to withstand the high-pressure environment of hydrogen, ensuring a safe and stable hydrogenation process. Hydrogen fuel cell system: In hydrogen fuel cells, valves are used to control the supply of hydrogen and oxygen and the discharge of reaction products, which have a significant impact on the performance and life of the fuel cell. Hydrogen storage system: Valves play a key role in the hydrogen storage system, which is used to control the storage and release of hydrogen and ensure the safe and efficient operation of the hydrogen storage system.
Lubricant and coolant management systems for the wind energy industry: Valves can provide reliable fluid control during the maintenance of wind turbine gearboxes and generators that require regular maintenance and replacement of lubricants or coolants, ensuring operational safety and efficiency. Braking system: In the braking system of wind turbines, valves are used to control the flow of brake fluid to achieve braking and safety control of the turbine.
Biomass conversion process in the field of biomass energy: In the process of converting biomass into fuel or electricity, it may involve the treatment of acidic or corrosive fluids, and valves can prevent the corrosion of the fluid to the equipment and prolong the service life of the equipment. Gas delivery and control: Gases such as biogas are generated in the process of biomass energy conversion, and valves are used to control the delivery and pressure regulation of these gases to ensure the stable operation of the system.
Thermal Management System for New Energy Vehicles The thermal management system of new energy vehicles is crucial to the performance and life of the battery, and valves are used in the thermal management system to control the flow and flow direction of fluids such as coolant and refrigerant, so as to achieve precise control of the battery temperature and prevent the battery from overheating or overcooling. For example, solenoid valve body products can be applied to the thermal management system of new energy vehicles.
Energy storage system Battery energy storage system: In the battery energy storage system, valves are used to control the connection and disconnection between the battery packs, as well as the connection between the battery packs and external circuits, to ensure the safe and stable operation of the energy storage system. Other energy storage systems: For other types of energy storage systems, such as compressed air energy storage, pumped hydro storage, etc., valves also play an important role in fluid control, pressure regulation, etc.
03Valve technology innovation helps the development of new energy industry
1. Intelligent: With the development of artificial intelligence, big data and other technologies, valve products are gradually moving towards the direction of intelligence. The intelligent valve can realize remote monitoring, fault warning and other functions to improve the operation efficiency of new energy equipment.
2. Corrosion resistance: In the new energy industry, some fields involve corrosive chemicals. The application of corrosion-resistant valves can reduce the failure rate of equipment and extend the service life.
3. High temperature and high pressure: During the operation of new energy equipment, some working conditions have the characteristics of high temperature and high pressure. The application of high temperature and high pressure valves can ensure the safe and stable operation of the system.
4. Energy conservation and environmental protection: The new energy industry pays attention to energy conservation and environmental protection. The application of low-resistance, zero-leakage valves helps to reduce system energy consumption and reduce environmental pollution.
With the continuous development and innovation of new energy technology, the valve industry is also facing huge development opportunities and challenges. On the one hand, the promotion and application of clean energy has promoted the continuous growth of valve demand; On the other hand, the performance and quality requirements for valve products are also getting higher and higher. Therefore, valve enterprises need to strengthen technological innovation and industrial upgrading, and continuously improve the added value and market competitiveness of products. At the same time, valve enterprises also need to pay attention to the changes in industry policies and market demand, and adjust the strategic direction and product layout in a timely manner to meet the needs of market changes and development. To sum up, the application of valves in the field of new energy has a wide range of prospects and important value. In the future, with the continuous development and innovation of new energy technology, valves will play a more important role.
