【Ten Years of Rapid Development in Chemical Processing Equipment】PEM electrolyzers of megawatt class with a customized hydrogen production capacity of 250 standard cubic meters per hour, from 2006 to 2023

Thread Content

The chemical processing industry has seen significant development over the past decade; let’s praise the prosperity and strength of modern China. By contributing our ideas, we can foster more active participation from everyone. HaiChuan becomes even better with your involvement – we welcome everyone to join in the forum discussions. With the high temperatures in July, be careful to prevent fires. Recently, Shanghai Hysun New Energy Technology Co., Ltd., a wholly-owned subsidiary of SHENENG Group (referred to as “Hysun Technology”), and its another subsidiary, Shanghai Hysun Innovation Energy Technology Co., Ltd. (referred to as “Hysun Energy”), released PEM electrolyzers of megawatt-class power that were developed independently. Each electrolyzer is capable of producing 250 standard cubic meters of hydrogen per hour, and it can operate stably within a wide power input range of 5% to 150%, thereby significantly improving both the performance and economic efficiency of these electrolyzers. Megawatt-class PEM electrolyzers are expected to address a range of technical challenges in hydrogen production and storage, helping to achieve the \"dual carbon\" goals. Independent technological innovation is accelerating the commercialization of hydrogen energy. Achieving carbon peak and carbon neutrality entails a broad and profound transformation of the energy system. Hydrogen serves as an important industrial raw material as well as a medium for large-scale, seasonal energy storage, and it holds promise as a key component of a new energy system. **The \"Medium- and Long-Term Plan for the Development of the Hydrogen Energy Industry (2021–2035)\") jointly issued by the National Development and Reform Commission and the **Energy Administration states clearly that hydrogen energy is an important component of the future **energy system. It is necessary to make full use of hydrogen energy as an important medium for the large-scale and efficient utilization of renewable energy, as well as of its advantages in terms of large-scale, long-duration energy storage. This will facilitate the optimal allocation of different types of energy across regions and seasons, promote the integration of hydrogen energy, electrical energy, and thermal energy systems, and help establish a modern energy supply system that features diversity and complementary integration. It is reported that alkaline electrolysis is currently widely used in China for hydrogen production; however, due to its long start-up and shutdown times as well as slow dynamic response, it struggles to meet the demands of the renewable energy market, which is characterized by rapid fluctuations. PEM electrolysis systems offer a wider operating range and shorter response times. However, due to immature technologies in areas such as engineering, design, and manufacturing, PEM electrolyzers in China are still mainly in the stage of small-scale pilot applications, which results in low power per cell, high acquisition costs, and high operational energy consumption. To address the issues of PEM electrolyzers being unable to be scaled up, remaining too expensive to purchase, and too costly to operate, Hysung Energy established a R&D team focused on material development, flow field design, as well as the development of manufacturing processes and equipment. Leveraging its long-term technical expertise in the fuel cell industry, the company invested nearly 100 million yuan in research and development efforts. As a result, it developed high-performance catalyst technologies, large-area membrane electrode coating techniques, high-precision flow field plate manufacturing methods, and highly consistent electrolyzer assembly techniques. These advancements transformed the materials, structure, and manufacturing processes used in existing electrolyzers, thereby solving problems related to product performance and reliability.
