As a national demonstration project with profound strategic significance

Amid the rapid development of China's new energy storage industry, the "Xinjiang Mulei 1,000 MW Carbon Dioxide Compressed Air Energy Storage Integrated Energy Demonstration Project" launched by the National Energy Administration marks a major milestone. As the world's largest gas energy storage power station of its kind, it leverages Xinjiang's abundant wind and solar resources to convert surplus electricity into high-pressure liquid gas during off-peak hours, which is then released to generate power during peak demand. This project represents a critical technological pathway for building a new-type power system and achieving China's dual-carbon goals.

BAOYI's independently developed high-pressure differential cut-off valve for carbon-oxygen gas energy storage systems incorporates multiple advanced technologies. It meets the stringent performance requirements of the system—including resistance to extreme pressure differentials, endurance under high-low temperature cycles, rapid shut-off, and high sealing reliability—providing essential support for the safe, efficient, and stable operation of megawatt-level gas energy storage power stations. This achievement strengthens China’s autonomous capability in high-end energy storage equipment and reinforces the country's leading position in the global competition for new energy storage technologies.

Breakthrough in Core Technology, Upgrade in Safety Assurance

The high-pressure differential cut-off valve for carbon-oxygen gas energy storage systems, successfully applied by BAOYI Group, is specifically designed for high-pressure gas energy storage systems in high-altitude and large-temperature-difference environments. It meets critical performance requirements such as high-pressure differential resistance, large flow capacity, rapid shut-off, and long service life. Its main core technological features include:

High-Pressure Differential Self-Adaptation:

An internal balancing structure effectively offsets destructive forces generated by extreme system pressure differences, reducing valve operating torque and extending service life.

Millisecond-Level Response for Precision Shut-Off:

A modular design enables independent zonal control, ensuring rapid full or partial cut-off upon abnormal signals and strengthening safety protection.

Sealing Reliability Under High-Low Temperature Cycles:

Specially developed sealing materials and structural designs adapt to high-low temperature variations, maintaining reliable sealing even at critical gas-liquid phase transition points during high-pressure gas liquefaction, eliminating leakage risks.

Intelligent Collaborative Control:

Supports deep integration with the energy storage system’s DCS control system, enabling smart cluster control and real-time status monitoring of valve units.

The deployment of this specialized valve marks a significant achievement in China’s independent breakthrough in core technologies for high-end industrial valves under extreme operating conditions, advancing the localization of critical components.

Dedicated to Special Valves, Forging the "Heart of China" in Fluid Control

As a leading enterprise in China’s valve industry, BAOYI Group has long focused on the R&D and manufacturing of valves designed for extreme conditions such as ultra-low temperatures, ultra-high pressure, and high corrosion resistance. Its products are widely used in nuclear power, ultra-supercritical thermal power, large-scale petroleum and petrochemical projects, LNG, and other critical sectors. The successful application in the Mulei project not only demonstrates BAOYI's technological innovation capabilities but also aligns with the national strategy for energy transition.

“The Mulei project serves as an ideal validation of the performance and reliability of BAOYI valves,” stated a technical representative of BAOYI Group. The high-pressure differential cut-off valve for carbon-oxygen gas energy storage systems embodies years of technical accumulation by the company. Moving forward, BAOYI will continue to innovate, delivering more tailored solutions to support additional green energy demonstration projects and uphold its commitment to collaborative, low-carbon development with partners.
