The choice behind the six “firsts.

As a national key science and technology project in the context of the Winter Olympics, China’s first 70 mpa skidded fully integrated hydrogenation station was developed by CIMC Enric Holdings Limited (Enric), using Siemens process control products and solutions. The product attracted the attention of the whole industry as soon as it came out, and set six “first” in the industry in the Chinese market!

This is the first multi-functional fully integrated hydrogenation unit, which integrates many systems such as gas discharge, pressurization, control, AI intelligent monitoring, etc. The first 70 mpa refueling system to meet the T40 level of the internationally recognized Ground Vehicle Standard – Light Vehicle Hydrogen Refueling Agreement; The first skid hydrogenation unit to complete the explosion-proof certification of the whole machine. In addition, in the field of skid-mounted hydrogenation units, whether it is multi-gas source hydrogenation, explosion-proof cold water system, integrated large screen application, it has achieved the first integration. For Siemens, this is also the first application of its distributed control system, SIMATIC PCS 7, on an integrated hydroloader.

Anruike is an advanced intelligent manufacturer of clean energy equipment under China International Marine Containers (Group) Co., LTD., and has accumulated a full understanding and trust with Siemens in the LNG system integration project, Hebei Xiongan oil and gas hydrogen integrated energy service station and other projects.

“The importance of the 70 mpa fully integrated hydrogen refueling station project is beyond doubt, and we must ensure that the product is the best of the best in every aspect.” Peng Na Zhang, Technical Director of the Hydrogen Division of Enric, said, “Enric has a long history of cooperation with Siemens. Together, we will provide safe and green energy guarantee for this international sports event, and gradually give this landmark product more application scenarios in the future, contributing to the achievement of China’s ‘double carbon’ goal.”

Simple to drive complex, face high pressure challenges

There’s a race going on in the hydrogen field. Taking hydrogen refueling stations as an example, the industry generally has two hydrogen filling capacities of 35 mpa and 70 mpa. Compared with 35 mpa, 70 mpa compressed hydrogen has higher energy density, faster filling efficiency and better economic performance. Taking an ordinary hydrogen fuel cell vehicle as an example, when the filling pressure is 35 mpa, it can travel 320 kilometers; When the filling pressure reaches 70 mpa, the driving range can be increased to more than 600 kilometers.

As a strong participant in this “race”, Enrico wants to take a path that has never been followed before, focusing on creating a standardized, systematic, skied fully integrated refueling station, and achieving its mobility while increasing the refueling pressure to 70 mpa.

The control system, like the brain of a hydrogen refueling station, is undoubtedly an important part of the technical layout. SIMATIC PCS 7, a process control system based on fully integrated automation technology, has powerful functions, high reliability and flexible scalability, and can control the hydrogen refueling station quickly and accurately. The process controller is responsible for the signal connection of the start button, pressure sensor and temperature sensor, as well as the control of the diaphragm compressor, cooling fan, circulating water pump and valve; The safety controller is connected to the SCram signal detection module, hydrogen leak detection module and fire detection module. With its unique scalability, high reliability and high flexibility, SIMATIC PCS 7 is the “go-to man” to help Enric achieve its goals, ensuring the safe and stable operation of all equipment.

The SIMATIC PCS 7 modular configuration method also contributes greatly to the improvement of efficiency. Its high degree of standardization enables Enric to save a lot of time and cost during the project implementation phase. The task-oriented operating interface and unified status alarm function make the interaction more convenient and intuitive, improve the operation efficiency of the process and reduce the operation and maintenance costs.

In Siemens’ view, with the large-scale development of hydrogen production projects, more and more hydrogen energy owners will choose to fully integrated automated control of all equipment, so as to achieve efficient and energy-saving operation of the project. Under this trend, the demand for distributed centralized control systems will increase and gradually become the “standard” for large-scale hydrogen production projects in the future. The application of SIMATIC PCS 7 in the 70 MPA skid-mounted fully integrated hydrogen refueling station will serve as a demonstration for the design and configuration of such products.
