【Ten Years of Great Progress in Chemical Engineering Technology】Launch of the High-Reliability High-Pressure Hydrogen Storage Vessels Project from 2008 to 2023
Thread Content
On May 22, 2023, the launch meeting for the **key research and development project “Design and Manufacturing Technology for High-Reliability High-Pressure Hydrogen Storage Vessels”**, led by Hefei General Machinery Research Institute Co., Ltd. and involving 10 other organizations including the China Special Equipment Inspection and Research Institute and Lanzhou Lanshi Heavy Equipment Co., Ltd., as well as a meeting to discuss the implementation plan, were held in Hefei. This project is a key special initiative under the **Key R&D Program for Hydrogen Energy Technology**. Addressing the critical needs for high-security, high-density, and low-cost hydrogen storage in hydrogen production plants and hydrogen refueling stations, this project focuses on the development of ultra-high strength and toughness steel plates, along with corresponding forgings and welding materials. It aims to overcome key technical challenges such as hydrogen storage vessel design based on risk and lifespan assessment, cold forming processes for thick-walled vessels with large curvatures, prevention of welding cold cracks and reheat cracks, as well as defect detection and repair. By creating highly reliable high-pressure hydrogen storage vessels, this project seeks to solve the key problems associated with large-scale hydrogen storage in China and promote the development of the country’s hydrogen energy industry. 、
“\"Design and Manufacturing Technology for High-Reliability High-Pressure Hydrogen Storage Vessels\" is a key project under the **Key R&D Program on Hydrogen Energy Technology**. Addressing the critical needs of hydrogen production plants and hydrogen refueling stations for high-security, high-density, and low-cost hydrogen storage, this project focuses on the development of ultra-high strength and toughness steel plates, as well as associated forgings and welding materials. It aims to overcome key technical challenges such as hydrogen storage vessel design based on risk and lifespan considerations, cold forming processes for thick-walled vessels with large curvatures, prevention of welding cold cracks and reheat cracks, and defect detection and repair. By establishing a comprehensive set of technical methods for the design and manufacturing of highly reliable high-pressure hydrogen storage vessels, this project seeks to develop such vessels that can address the key issues related to large-scale hydrogen storage in China, thereby promoting the development of the country’s hydrogen energy industry. Lanshi Heavy Equipment focuses on **strategic needs, continuously increasing its efforts in technological innovation. It is involved in research related to the design and manufacturing of high-parameter steel hydrogen storage pressure vessels based on risk and lifespan considerations, as well as in technologies for defect detection, safety assessment, and repair of thick-walled hydrogen storage pressure vessels. In this way, it contributes to the development of a country strong in science and technology and in manufacturing.
