? ? ? On July 20th, our company participated in the preparation of the GB standard "Gas Hydrogen Mixing Device" at the invitation of the Standards Committee. Hydrogen is recognized as a truly clean energy source worldwide. We believe that the issuance and implementation of this standard will provide important technical basis for China to achieve its goals of carbon peak and carbon neutrality as soon as possible. Our company has currently participated in the compilation of multiple national standards in the industry. This active participation has fully leveraged our technical advantages and made due contributions to high-end technology and new standards in the industry.
