Let’s give praise and support to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Progress in Chemical Engineering Equipment】A continuously updated summary post is available – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** Recently, the project “Research on Key Equipment and Safety Aspects Related to the Production, Storage, Transportation, and Refueling of Liquid Hydrogen”, which is part of the key research program on renewable energy and hydrogen technology and in which the Institute of Physics and Chemistry was involved, successfully passed the comprehensive performance evaluation. The comprehensive performance evaluation meeting for the project was organized by the High Technology Research and Development Center of the National Natural Science Foundation of China. Experts from institutions such as Wuhan University of Technology, Youyan Engineering Technology Research Institute Co., Ltd., Beijing Aerospace Test Technology Institute, Beijing Bokern Energy Saving Technology Co., Ltd., China Classification Society Quality Certification Company, Hefei University of Technology, and Zhejiang University visited the demonstration site, reviewed relevant documents, and listened to a report on the comprehensive performance evaluation presented by Xie Xiujuan, a researcher at the National Key Laboratory of Cryogenic Science and Technology affiliated with the Institute of Physics and Chemistry, Chinese Academy of Sciences, who is in charge of the project. Following inquiries and discussions, it was determined that the project had completed the research tasks specified in the task statement and met the expected goals and assessment criteria; therefore, it was unanimously agreed to approve the comprehensive performance evaluation of the project. As the leading entity of the project, Beijing Zhongke Fuhai Cryogenic Technology Co., Ltd. is working together with the Institute of Physical and Chemical Technology of the Chinese Academy of Sciences, Beijing Special Equipment Engineering Design Institute, Tongji University, China Special Equipment Inspection and Research Institute, Zhangjiagang CIMC Suntain Cryogenic Equipment Co., Ltd., Xi’an Jiaotong University, Shanghai Shunhua New Energy System Co., Ltd., and CSSC Pengli (Nanjing) Ultra-Cryogenic Technology Co., Ltd. to carry out this project. As the project sponsor, the Institute of Physical and Chemical Technology, Chinese Academy of Sciences, made key advancements in this project in areas such as the optimization of the hydrogen liquefaction process for large-scale, high-efficiency liquid hydrogen production; the integration of normal and parahydrogen conversion processes with heat exchange; the development of heavy-duty hydrogen turbine expanders; and integrated control technologies. As verified through third-party testing or on-site verification by experts, the high-speed, heavy-duty hydrogen turbine expander developed achieves a maximum adiabatic efficiency of 83.52%, while the integrated heat exchanger for efficient conversion of primary and secondary hydrogen gases reaches a maximum heat transfer efficiency of 96.77%. The system integration and control technology package for liquid hydrogen production equipment possesses independent intellectual property rights, enabling the independent development of key technologies and core equipment. It has been demonstrated in a liquid hydrogen plant in Fuyang City, Anhui Province, effectively ensuring the achievement of the project’s overall objectives: a liquefaction capacity of 5.27 tons per day under rated conditions, as well as a hydrogen liquefaction energy consumption of 11.8 kW·h/kg of LH2. This achievement is of great significance for the localization of key technologies and equipment related to liquid hydrogen production, storage, transportation, hydrogenation, and safety in our country, as well as for the independent and sustainable development of hydrogen fuel vehicles, green hydrogen industries in China, and the aerospace industry. The National Key Laboratory of Cryogenic Science and Technology at the Institute of Physical and Chemical Technology, Chinese Academy of Sciences, provided strong support for the successful holding of the conference.
