Hydrogen, which can react with oxygen to form water, is an ideal secondary energy source. Among them, hydrogen produced by renewable energy sources such as solar and wind power is called green hydrogen. Green hydrogen has great development potential due to its zero carbon emission. Green hydrogen industry chain from hydrogen production, storage and transportation to hydrogen fuel cell applications is attracting much attention.
Therefore, this article specially collates the hydrogen-related products on display at Chinaplas recently. The main products are as follows:
●PPS is used in the diaphragm of alkaline hydrogen electrolytic cell and the end plate of fuel cell.
●PA is used in hydrogen storage bottles and hydrogen transmission lines;
●Proton exchange membrane, PTFE electrolytic cell seal gasket, etc.

3. Deyang Keji High-tech Materials : PPS hydrogen diaphragm
Deyang Keji High-tech Materials Co., Ltd. engaged in the research and development, modification and production of PPS, PEEK and other engineering plastics. The main products of the company are polyphenylene sulfide filament, special basalt cloth, modified PPS hydrogen production diaphragm, etc.
Ⅱ.PA is used in hydrogen storage bottles and hydrogen transmission lines
4. Evonik: PA12 hydrogen transport tube, gas separation membrane
The multi-layer hydrogen delivery tube made of Evonik polyamide 12(VESTAMID®) is lighter than conventional metal pipes, and the fluorine material inside is cleaner and protects against hydrogen embritzement.
VESTAMID®Hydrogen delivery pipe
The pipeline, made of VESTAMID®NRGPA12, will create a more cost-effective gas transmission and distribution network. The maximum working pressure of PA12 pipeline is 18Bar, which can replace the carbon steel pipeline in the gas transmission network. Due to the extremely low permeability coefficient of the PA12 pipeline, its safety has been certified by DVGW as H2 Ready, making it more suitable for hydrogen delivery related applications.
VESTAMID® NRG Natural gas/hydrogen lines
Evonik SEPURAN® brand stands for customized hollow fiber membranes designed for high efficiency gas separation. It can be used for separation and purification of methane, nitrogen, hydrogen and other gases. SEPURAN®Noble membranes selectively extract and recover high concentrations of hydrogen gas from natural gas pipelines transporting a mixture of methane and hydrogen gas.

6. Lotte Chemical: Hydrogen storage tank (PA lining +CF composite winding)
Lotte Chemical is working to become carbon neutral. In order to provide the optimal hydrogen storage solution, Lotte Chemical has developed the Type IV (Type 4) lightweight high-pressure hydrogen storage container and established the Pilot production line, which is laying the foundation for a variety of hydrogen mobility fields such as hydrogen electric vehicles (passenger vehicles/commercial vehicles), industrial machinery/construction machinery, and unmanned aerial vehicles.
In particular, the world’s highest weight loss ratio (6.2wt%) was achieved through the development of a one-piece liner that simplified the process and enhanced air tightness, and increased productivity through the development of a dry winding process and the optimization of winding lines.
