FAQ

Based on the accumulated experience in equipment manufacturing and the in-depth understanding of the demand for large-scale hydrogen production from wind, solar and green power, SANY Hydrogen Energy has spotted five major technological development trends of alkaline electrolyzers:
First, it is the high electric current density. In the future, the electric current density will increase from 2500-3500 A/m2 to 4000-12000 A/m². The equipment cost will be reduced by 20%, and the operating load range will be widened by 10%.
Second, it is the large scale (large-scale hydrogen production capacity of a single electrolyzer and large-scale hydrogen production capacity of the project). In the future, the hydrogen production capacity of a single electrolyzer will increase from generally 1000 Nm3/h to 2000-3000 Nm³/h. The total hydrogen production capacity of the project will increase from currently 100MW level to the GW level, while a smaller number of electrolyzers in total are required for scenarios of the same scale. The project revenue will increase by 20%.
Third, it is the wide power fluctuation range. The valley of the power fluctuation range will drop from 40% to 10%, while the peak will scale from 110% to 120% or even higher. The utilization rate of green power is expected to increase by more than 10% with safer equipment.
Fourth, it is the module-oriented design. At present, most electrolyzers are customized and developed for chemical equipment, which is against the overall cost reduction trend of intelligent manufacturing. The module-oriented design concept and intelligent manufacturing technology enable the structural assembly of the electrolytic chamber, and ultra-large-scale mass production and interchange of key components, which makes the equipment more stable and manufacturing more efficient.
Fifth, it is the intelligent control. In the future, based on new scenarios and new solutions for hydrogen production, SANY Hydrogen Energy will build an ultra-large-scale GW-level platform for flexible cluster control and global energy management to ensure the safety, reliability and cost-efficiency of chemical equipment.

The SIEMS Energy Management System of SANY Hydrogen Energy is the brain of the GW-level solution of SANY Hydrogen Energy, which is superior because it can support minute-level predictions for wind and solar energy systems to drive the hydrogen production control system based on millions of kernel data, and to realize the quick coordination of energy while maintaining the off-grid interfaces. Moreover, the self-developed cluster control algorithm can cover the computility of more than 80 sets of electrolyzers while the underlying safety mechanism is maintained.

The GW-level hydrogen production solution includes 66 large-capacity square electrolyzers, 22 sets of all-in-one gas-liquid separation systems, 11 sets of all-in-one purification systems, 66 sets of high-performance power supplies, and 1 set of SANY’s self-developed SIEMS Energy Management System that increases the overall green power utilization rate by 10%. Its significant advantages include smaller footprint, an decrease in maintenance costs by 30% based on the module-oriented design and a maximum operating power density of 12,000 A/m².

Since its founding, SANY Hydrogen Energy has been focusing on research and development, and successfully launched a series of circular electrolyzer products of which the overall performance is significantly improved. The uniformity of the flow field and temperature field are enhanced greatly by strengthening the sealing structure and fastening system, and using the emulation capability. At the same time, a new generation of electrodes, membranes and gaskets have been introduced to comprehensively upgrade the overall manufacturing process, thus greatly improving the operating cost-efficiency and reliability of the electrolyzer.
SANY Hydrogen Energy R&D Testing Center has been set up in Beijing, which has formulated experimental procedures for electrodes and membranes, and tested 56 types of electrodes, forming an industry-wide electrode database to provide more data support for the selection of equipment model.
On the other hand, through independent R&D and cooperation with companies such as Baoshilai, we have accumulated sufficient reserves of technologies of related electrode performance, which has been successfully applied to a series of electrolyzer products.
As for gaskets, we compared the core parameters of multiple gasket manufacturers to provide solid support for product selection and design. In terms of manufacturing processes, we have made full use of the advantages of intelligent manufacturing to create a 1.5GW-level automatic product line, representing a breakthrough in blanking, automatic welding, pipeline prefabrication and high-precision assembly, which greatly improves the stability of the equipment. This series of innovations and efforts have made SANY Hydrogen more competitive in the field of hydrogen production equipment, providing users with more efficient and reliable products.

In terms of hydrogen production equipment, we have launched a group of star products:
(S-series) Circular Electrolyzer: including 2000 Nm³/h Alkaline Electrolyzer and All-in-one AWE Hydrogen Production Equipment.
(G-series) Square Electrolyzer: 3000 Nm³/h Square Alkaline Electrolyzer launched. With respect to hydrogen refueling equipment, the product that we are proud of is our package system solutions for “integrated hydrogen production and refueling stations”.
These products are the congregation of the innovative and technical strength of SANY Hydrogen Energy, which will surely provide users with efficient and reliable solutions for hydrogen production and refueling, growing into star products that have drawn great attention in the industry.

Though most manufacturers on the market mainly conduct the testing at the user end, SANY Hydrogen Energy, as a company focusing on equipment manufacturing, always holds that the overall testing of electrolyzers should be finished within the manufacturing plant of the principal equipment. Therefore, we have established the largest 20 MW equipment testing platform within the industry, which is capable of the testing for 3 to 3000 Nm³/h single electrolyzer. In addition, there is also an all-in-one testing center.
Based on thousands of hours of testing in total, we can provide more sufficient data support for the iteration of electrolyzers, BOPs and auxiliary equipment. Meanwhile, we also focus on performance testing, integration development, energy management and optimization and other related work, and have formulated and released the testing standards for the Equipment Testing Standards of SANY Hydrogen Energy for All-in-one Electrolyzers. We are working closely together with competent authorities, industry associations, design institutes, customers and certification organizations for the formulation of industry standards to promote the development of the entire industry. Through continuous testing and the formulation of standards, SANY Hydrogen Energy is committed to providing customers with more reliable and efficient electrolyzers and related equipment to support the development of the entire hydrogen energy industry.

No. First of all, the design and manufacturing of products conform to the legal requirements and safety standards of countries and regions where the products are used. Secondly, every product has been tested and verified several times of which the performance is guaranteed. At the same time, we have a sophisticated after-sales service system to ensure that the products will run smoothly on the production site.
