Recently, Sinopec Oilfild Equipment Corporation (SOFE) won the bid of the diaphragm hydrogen compressor project to fully serve the storage and transportation construction of high purity hydrogen in the Beijing-Tianjin-Hebei region. This marks the company's diaphragm hydrogen compressor obtained a commercial order again.

In 2023, SOFE won the commercial order of diaphragm hydrogen compressor for the first time, and delivered the products within one year. The largest single large compression ratio diaphragm hydrogen compressor independently developed in China will help the development of hydrogen energy industry in the Guangdong-Hong Kong-Macao Greater Bay Area.

Hydrogen compressors are usually used for hydrogen storage, transportation and usage. They work by changing the gas volume to achieve the required pressure and flow.

Anchoring hydrogen equipment, SOFE focus on substitution of imported parts and "neck" technology research, relying on the ultra-high pressure structure technology, ultra high hard material technology, ultra high control technology, advanced manufacturing technology as the core of science and technology innovation system, basic research on the application of hydrogen equipment, the system building research and development system, priority in the hydrogenation, hydrogen, hydrogen production, hydrogen compressor, hydrogen station complete equipment, hydrogen production equipment, intelligent safety system, hydrogen management, hydrogen steel pipe, breakthrough in high pressure hydrogen material, high pressure oil sealing, large flow low impact electrohydraulic control key core technology, obtained more than 50 pieces patents in the related area.

On the development of liquid drive hydrogen compressor, using a double pressure, pressure ratio dynamic adjustment design, Overcome the technology of large flow low impact controllable pressure ratio electrohydraulic control, high pressure oil sealing, wide gas valve design,. Independent research and development of domestic first hydrogenation station with 90 trillion liquid drive hydrogen compressor completed the limit performance test, equipment is stable and reliable. 

On diaphragm type hydrogen compressor research and development, make a breakthrough in membrane cavity line optimization design, high efficiency oil spill system design, developed 22 trillion, 1700 standard cubic meters per hour, 70% volume efficiency of diaphragm type hydrogen compressor, help to build a 10,000 square scale hydrogen supply center, and support to higher pressure level for hydrogen filling process prospective technology research.

In the service Beijing-Tianjin-Hebei region user hydrogen center project construction, SOFE closely around the user demand, actively carry out market research, targeted development 2.0-2.9 inlet pressure, export pressure 22Mpa, in the intake pressure 2.7 Mpa, discharge 1780 standard cubic meters per hour of efficient large displacement diaphragm hydrogen compressor.

At present, SOFE has the ability to provide clients with standardized hydrogenation station solutions and integrated solutions for hydrogen production and hydrogenation. It provides customers with key equipment products, technologies and services in hydrogen production, hydrogen transmission, hydrogenation and other fields, and a variety of hydrogen equipment to accelerate the market.
