Against the backdrop of ongoing energy structure transformation and the continuous advancement of the "dual carbon" goals, hydrogen energy, as a crucial carrier of clean energy, has drawn industry-wide attention 

to its efficient and stable production. Recently, we are delighted to see that our partner Baotou Steel's "Hydrogen Oil Removal and Nitrogen Regeneration High-Efficiency Oil Removal Method" has been successfully 

selected as an "Advanced Operation Method.".

As a partner advancing hand in hand with Baogang Co., ShanghaiTongzhu has always focused on technological innovation and coordinated development across the industrial chain. This breakthrough by Baogang Co. not 

only provides a practical model for the industry to learn from but also fills us with confidence in our deep collaboration in the hydrogen energy sector.

As an innovative enterprise specializing in energy technology services, Shanghai Tongzhu consistently prioritizes "empowering the green upgrading of industries" as its core mission. We deeply understand that the 

stable operation of the hydrogen energy industry chain relies on meticulous refinement at every stage. The advanced operation method selected by Baogang Co., Ltd. this time focuses on the pretreatment stage of 

the PSA system for coke oven gas, directly addressing the pain points of traditional processes—such as cumbersome operations, high equipment wear, and excessive energy consumption. Through process innovation, it 

achieves a leap from "passive response" to "active optimization." This relentless pursuit of technical details aligns perfectly with Shanghai Tongzhu's philosophy of "solving practical problems through innovation.".

For a long time, Shanghai Tongzhu has maintained a close cooperative relationship with Baogang Co., Ltd. In the field of hydrogen energy production and application, we jointly explore technical implementation 

scenarios and promote collaborative innovation across the industrial chain. This technological breakthrough by Baogang Co., Ltd. vividly exemplifies the "complementary strengths and resource sharing" cooperation 

model between the two parties.

As a practitioner in the energy technology service sector, Shanghai Tongzhu firmly believes that the coordinated development of the industrial chain is the key to advancing the industry. Shanghai Tongzhu is willing 

to further deepen cooperation with Baogang Co., Ltd., enhancing synergy in technology exchange, resource sharing, and scenario expansion. Together, we will explore innovative solutions for hydrogen energy production, 

storage, transportation, and application, contributing more to the industry's green transformation.

The successful selection of Baogang Co., Ltd.'s "High-Efficiency Oil Removal Operation Method for Hydrogen Purification Oil Remover with Nitrogen Regeneration" marks a significant milestone in the collaboration 

between both parties. Building on this achievement, Shanghai Tongzhu will continue to uphold the development philosophy of "innovation, collaboration, and sustainability," working hand in hand with Baogang Co., Ltd. 

to deepen expertise in the hydrogen energy sector. Together, they will pioneer a new chapter of collaborative innovation within the industrial chain, injecting greater momentum toward achieving the "dual carbon" 

goals and fostering high-quality industry development.
