Ten years of rapid development in chemical engineering equipment – praising the prosperity and strength of modern China. This is just a starting point; more participation from everyone will make things even more lively. HaiChuan becomes even better with your involvement; we welcome everyone to join in the forum discussions. Everyone should focus on safety and know how to handle emergencies. ********************************************* On June 1, 2023, the world’s first 1300 Nm3/h high-current-density pressure-type alkaline water electrolyzer, developed under the leadership of Huaneng Qingneng Institute and Huaneng Sichuan Hydrogen Energy Company, was successfully installed at the Huaneng Pengzhou hydrogen production innovation project site. This marks the entry of this demonstration project into the phase of installing its core equipment. With the support of China Huaneng Group’s “Top 10 Technology Projects,” the electrolyzer developed by the project team has enabled an upgrade in the technology for producing hydrogen through alkaline water electrolysis. Its rated hydrogen production capacity is 1300 Nm3/h, with a maximum capacity of up to 1500 Nm3/h; it is currently the alkaline electrolyzer with the highest hydrogen production capacity among those used in commercial demonstrations ； Rated current density is 5000 A/㎡, with a maximum of up to 6000 A/㎡ ； The DC energy consumption is below 4.2 kWh/Nm3H2 ； The volume-to-capacity ratio dropped to 0.73; these various key indicators have set a benchmark for both the international and domestic industries, providing new impetus for reducing the cost of green hydrogen. By increasing the current density and electrolysis efficiency, the volume of a 1300 Nm3/h electrolyzer can be reduced by more than one-third compared to a conventional 1000 Nm3/h electrolyzer, resulting in a 25% reduction in the equipment investment cost per unit of hydrogen produced ； Compared to the industry average, the energy consumption for hydrogen production is reduced by 0.3 kWh/Nm3H2; thus, over 3.3 million kWh of electricity can be saved per thousand tons of hydrogen produced, resulting in significant energy savings.
The demonstration project includes 2 electrolyzers with a capacity of 1,300 Nm3/h each; the hydrogen produced by these electrolyzers is sufficient to power 500 hydrogen fuel cell vehicles. Once completed, this project will become the first large-scale hydrogen production facility of its kind in the southwestern region. It will also showcase new technologies such as 20/30 MPa dual-pressure hydrogen filling systems and intelligent control systems for the integrated production, storage, and refueling of hydrogen energy. Once the installation and commissioning phase begins, Huaneng Sichuan Hydrogen Energy Company and Huaneng Clean Energy Research Institute will continue to leverage the strengths of various stakeholders, optimize the construction plan, and arrange work schedules carefully, with the goal of completing the project and putting it into operation by the third quarter of this year. This will allow for the testing of efficient hydrogen production through electrolysis, thereby providing a hydrogen supply to support the high-quality development of the hydrogen industry in the Chengdu area at an early date. The project team has achieved innovation at multiple levels and in various aspects, including the development of key electrocatalyst materials, the design of core electrode plate components, and the assembly of large-scale electrolyzers. It has made breakthroughs in key technologies such as the production of large-scale, high-performance hydrogen-evolving and oxygen-evolving electrodes, as well as the optimization of the flow field structure of electrode plates. A systematic portfolio of intellectual property rights has been established; over 200 invention patents have been filed in the past two years, including more than 80 patents related to core electrolyzer components, over 40 patents related to electrolyzer equipment, and more than 60 patents related to hydrogen production systems. The number of new patents in the field of electrolytic hydrogen production ranks fourth in the world and first among state-owned enterprises, according to the \"Patent Insights on Innovation Trends in Hydrogen Production Electrolyzers\" report published by the European Patent Office and the International Renewable Energy Agency in 2022.

Don’t say that; it’s completely unscientific. The current density of electrolyzers in Europe is 10,000, and the production volume is even higher; one could take a look at ThyssenKrupp’s alkaline water electrolyzer technology in Germany. There’s no need for such word games.
The world’s first 1300 Nm3/h high-current-density pressure-type alkaline water electrolyzer – even the existing companies are acting in a mysterious manner

Weren’t the 2000 Nm3/h alkaline water electrolyzers produced by Su Huihui Energy just released a couple of days ago? How should we describe this world’s first set of such equipment?
On March 9, 2021, Huaneng Sichuan Company signed the \"Project Investment Agreement for the Huaneng Pengzhou Water Electrolysis Hydrogen Production Technology Innovation Demonstration Project\" with Pengzhou City **. Under the agreement, the Pengzhou Water Electrolysis for Hydrogen Production Technology Innovation Demonstration Project will be located in Chengdu’s New Materials Industry Zone. It will include a water electrolysis hydrogen production facility with a capacity of 2,600 standard cubic meters per hour, high-density hydrogen storage equipment and hydrogen refueling stations, as well as the Huaneng Sichuan Green Hydrogen Technology Innovation Institute and a comprehensive demonstration base for technologies related to the hydrogen industry chain. Completion of the project is scheduled for 2021.
