As a recognized clean energy, hydrogen energy is an important part for the transformation of the global energy structure, and it is also the key energy to realize the carbon neutrality strategy. Shanxi province of China has a total coking capacity of 140 million tons, and the byproduct coke oven gas that can be used for hydrogen production is about 28 billion standard cubic meters, all of which can produce 1.5 million tons of hydrogen annually.

Pengwan Hydrogen Port and Industrial Park, with an area of 77.5 square kilometers, known as the world's largest hydrogen energy industry project with the most complete industrial chain and super advanced process equipment. Critical communication is vital for safe running the project, Caltta DMR Trunking communications solution was selected and well deployed to safeguarding the production, which includes Caltta’s flagship ATEX approved terminal PH990Ex and PH910Ex.

PH990Ex and PH910Ex are DMR digital trunking radios with professional explosion-proof design. They have dual certifications for gas explosion-proof and dust explosion-proof with explosion-proof grade meeting Ex ib IIC T4 Gb/Ex ibD 21 T120℃ IP6X, and can be used in high-risk gas environments such as hydrogen, water gas, acetylene, and carbon disulfide. Also, they can support high-quality digital trunking voice and data services and meet the requirements of daily operation communications and emergency dispatch in the energy industry.

Caltta's professional explosion-proof communication products and solutions have been widely deployed in many energy verticals such as oil and gas, petrochemical, coal chemical, LNG, photovoltaic new materials, hydrogen energy industrial parks, coal mines, and so on. Together with our worldwide partners, let’s make communication safer and richer.
