Thread Content
China’s first 10kw AEM electrolyzer for hydrogen production: On February 16 of this year, Sunstone Hydrogen held a product launch event, introducing China’s first AEM electrolyzer. According to the information provided, each of these new AEM electrolyzers has a rated power of 2.5 kW, a DC power consumption of 4.3 kWh/Nm³, and an output pressure of 3 MPa. The maximum hydrogen production rate per electrolyzer is 600 L/h. They feature fast start-up times: it takes only 60 seconds to reach 0-100% during hot start-up, while the cold start-up time is no more than 5 minutes. Compared to 2.5kW devices, the 10kW version offers lower system costs, higher integration levels, smaller sizes, and broader application prospects in both domestic and international markets. This new model has been improved in terms of rated hydrogen production rate, actual system energy consumption, external dimensions, volume power density, and mass power density – resulting in lower costs per unit of hydrogen produced; the manufacturing cost per kilowatt is 40% lower compared to 2.5kW AEM electrolyzer systems for hydrogen production ； Higher integration level: more suitable for applications in the 10 kW to 100 kW range. A 1 MW containerized system requires 400 electrolyzers of 2.5 kW each, or 100 electrolyzers of 10 kW each ； Improved energy density: Hydrogen production systems based on water electrolysis feature high energy density and higher level of system integration. The width of such systems is increased by 10 cm compared to those with a power output of 2.5 kW, the height increases by 114 mm, the power output rises by 4 times, while the mass increase is less than double. Such a structure facilitates the integrated design of large-scale hydrogen production systems via water electrolysis ； Superior efficiency: The efficiency of water electrolysis for hydrogen production is higher, with a hydrogen production rate of 4.4 kWh/1 Nm3. The energy consumption of the BOP equipment in the water electrolysis system increases only slightly, resulting in a total system energy consumption of 4.5 kWh/Nm3. According to SteadyStone Hydrogen, the technical specifications of the 10 kW AEM water electrolysis system for hydrogen production are as follows: Rated output: 2000 L/h ； Operating life of electrolyzer > 50,000 hours ； Hydrogen output purity: mole fraction 99.5% ； Hydrogen output pressure: nominal value of 3 MPa; the pressure can be adjusted according to user requirements ； Purity water conductivity δ
Shenzhen Unistone Hydrogen Energy Technology Co., Ltd. (referred to as “Unistone Hydrogen Energy”) is a globally leading innovation company in the field of new energy. It is also the only company in the world that offers AEM electrolyzer systems for hydrogen production, with integrated research and development capabilities covering everything from membranes to catalysts, membrane electrodes, control systems, and system integration. Focusing on the research, development, and manufacturing of high-end technological equipment in the upstream sector of the hydrogen energy industry, Winsun Hydrogen has accumulated extensive experience in the research, development, production, and sales of products related to water electrolysis for hydrogen production, hydrogen production from solid waste, and hydrogen fuel cells, as well as in the development of applications for hydrogen production projects. It offers companies comprehensive solutions for the integrated use of hydrogen energy. Wenshi Hydrogen Energy possesses high-performance anion exchange membrane production technology with 100% independent intellectual property rights, AEM high-efficiency bimetallic catalyst production technology, high-efficiency OER and HER electrode production technology, as well as system integration and control technologies for electrolyzer systems. Its strong R&D capabilities signify that China’s hydrogen energy industry has moved from the era of system integration to a stage of development characterized by full independent intellectual property rights. In 2023, the Steunstone Hydrogen Energy team invested countless efforts and wisdom in product development and innovation, constantly striving for progress, challenging themselves, and achieving continuous breakthroughs. It is reported that on February 16 this year, Winstone Hydrogen Energy held a product launch event, introducing the country’s first AEM electrolyzer. At the end of July, Winstone Hydrogen Energy announced that it would complete the establishment of a production line for self-developed anion exchange membranes (AEM) by the end of 2023 and start small-scale production. At full production, the capacity in the first phase is 100,000 square meters (4GW). In addition, Unistone Hydrogen Energy is also planning to build an AEM electrolyzer production line, with construction set to begin in the fourth quarter of 2023. By 2025, it is expected that this production line will achieve an annual capacity of 1 GW. On August 1, Stable Stone Hydrogen Energy announced the completion of a new round of financing. The funds from this financing round will be used to expand the production capacity of AEM electrolyzers and to carry out small-scale production of anion exchange membranes, in order to meet the growing market demand for green hydrogen solutions. As previously revealed, by 2024, Winstone Hydrogen Energy will launch the world’s first 100kW single-cell electrolyzer. Unistone Hydrogen stated that increasing the specifications of individual electrolyzers is one of the key ways to reduce the cost of AEMs, and it will also accelerate the development of the AEM industry. The successful implementation of the anion exchange membrane and electrolyzer production lines independently developed by Steunstone Hydrogen represents a major breakthrough in the history of AEM electrolytic water generation technology. Unistone Hydrogen has become the world’s first company to possess the capability to independently develop and produce AEM electrolyzers and their key components. By 2025, thanks to the localization of technology and continuous improvements, Sunstone Hydrogen is expected to be able to reduce the cost of AEM electrolyzers to below 2,500 yuan/kW, which will greatly accelerate the commercialization of hydrogen production using AEM electrolysis. Stone Hydrogen remains true to its original aspirations and keeps moving forward. Looking to the future, Stone Hydrogen will further accelerate the expansion of large-scale hydrogen production through water electrolysis. It can provide green energy solutions for various applications, from small-scale home storage to distributed hydrogen production, as well as for large-scale hydrogen storage systems, enabling widespread adoption and use in different scenarios.
