ENRIC is a leading manufacturer of clean power equipment under World Marine Containers (Group) Co., Ltd. in China, and has accumulated full tacit understanding and trust with Siemens in projects such as LNG system integration project and Hebei Xiong'an oil, gas and hydrogen integrated power service station.
"The importance of the 70 megapascal skid-mounted fully integrated hydrogen refueling station project is undeniable, and it is necessary for us to ensure that the product reaches the best of the best in all aspects." Pengna Zhang, Technical Director of ENRIC's Hydrogen Energy Division, said, "ENRIC and Siemens have been cooperating for a long time. The strong alliance will provide safe and green power guarantee for this world-renowned sports event, and gradually give this milestone product more use scenarios in the future, and contribute to the achievement of China's 'double carbon' policy." ”
There is a race to catch up in the field of hydrogen. Taking hydrogen refueling stations as an example, the industry generally has two hydrogen refueling capacities: 35 megapascals and 70 megapascals. Compared with 35 megapascals, 70 megapascal compacted hydrogen has higher energy density, faster filling efficiency and better economic function. Take an ordinary hydrogen fuel cell vehicle as an example, when the refueling pressure is 35 megapascals, it can travel 320 kilometers; When the filling pressure reaches 70 megapascals, the cruising range can be increased to more than 600 kilometers.
As a strong participant in this "race", ENRIC expects to take a path that has no precedent to follow, focusing on building a standardized, systematic skid-mounted fully integrated hydrogen refueling station, and increasing the refueling pressure to 70 megapascals as well as completing its mobility.
The control system is like the brain of a hydrogen refueling station, which is undoubtedly an important part of the skill layout. The SIMATIC PCS 7 process control system, based on Totally Integrated Automation (NIMA), is characterized by high reliability and responsive scalability for fast and accurate control of hydrogen refueling stations. The process manipulator acts as the signal connection for 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 emergency stop signal detection module, hydrogen leakage detection module and fire detection module. With its unique scalability, high reliability and high sensitivity, SIMATIC PCS 7 is the "assistant" to ENRIC's approach and ensures the safe and stable operation of all equipment.
The modular configuration of SIMATIC PCS 7 also contributes to the progress of efficiency, with a high degree of standardization that saves ENRIC a lot of time and money during the implementation phase, while the mission-oriented operator interface and consistent status alarm function make the interaction more convenient and intuitive, improving the efficiency of the process and reducing the cost of operation and maintenance.
In Siemens' view, with the large-scale development of hydrogen production projects, more and more hydrogen energy owners will choose to fully integrate and automate all equipment, and then complete the 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 use of SIMATIC PCS 7 in a 70 MPa skid-mounted fully integrated hydrogen refueling station will serve as a model for the design and equipping of such products.
Gu Qing, Product Director of Control Systems at Siemens Digital Industries' Process Automation Business Unit, said: "Enric's innovative breakthrough has opened the industry's eyes to more possibilities for the use of hydrogen energy, and we are very proud that Siemens' proven distributed centralized control system can be used to help green hydrogen go further and more stable." ”
