【Ten Years of Rapid Development in Chemical Engineering Equipment】Lanshi Group’s Research and Development of Hydrogen-Electric Coupled Energy Storage Technology from 1276 to 2023
Thread Content
In recent years, Lansi Group has promoted the transformation and upgrading of its core industries as well as the development of strategic industries. It has actively invested in sectors such as nuclear energy, hydrogen, optics, and new energy materials for storage. The group has also made significant efforts in researching and applying technologies related to the integration of green electricity and green hydrogen for energy storage, thereby contributing to energy savings, carbon reduction, and improved efficiency – all in support of achieving the goals of carbon peak and carbon neutrality. As the core force behind technological innovation at Lanshi Group, Lanshi Research Institute closely monitors the development of technologies related to hydrogen-electric coupled energy storage. It has launched projects to develop off-grid hydrogen-electric coupled energy storage systems, and was approved to establish a special initiative for enhancing the R&D capabilities of enterprises above a certain size – namely, a Research and Development Center for New Types of Hydrogen (Ammonia) Energy Storage Technologies. Among them, the off-grid hydrogen-electricity coupled energy storage system development project addresses local consumption issues through scaled-up hydrogen energy storage (hydrogen production + storage), regulating the output from variable renewable energy sources to provide a stable power supply required for hydrogen storage, thereby reducing the impact of the variability and intermittency of renewable energy sources on the efficiency of hydrogen production via water electrolysis. The entire system mainly comprises units such as wind and solar power generation, electrochemical energy storage, water electrolysis for hydrogen production/storage, power conversion and distribution, and fuel cells. Through the integrated design of these unit systems, research on key control strategies, and the development of an energy management platform, this system aims to explore viable technical approaches for the large-scale production of hydrogen using off-grid renewable energy sources. In the future, Lansi Research Institute will focus on the core technologies of the green hydrogen industry, conduct in-depth research on the technologies and applications related to the hydrogen-electricity integration value chain, continue to strengthen the development of technologies for hydrogen-electricity integration energy storage as well as their market promotion, seize the opportunities presented by the development of hydrogen (ammonia) energy storage industries, and explore the best investment options under different scenarios in line with the needs of new energy applications in various fields, thereby promoting the expansion of such projects and their industrialization.
Is it necessary to use green electricity for hydrogen production, storage, and power generation? What do you think? ? ? ? https://bbs.hcbbs.com/thread-5497500-1-1.html (Source: Haichuan Chemical Industry Forum)
Not bad at all; it’s really great
“The “Research and Development of Off-grid Hydrogen-Electric Coupled Energy Storage System” project is one of the leading common technology projects undertaken by Lanshi Group in 2022, aimed at resolving the contradiction between the large-scale development of new energy sources such as photovoltaic and wind power and their effective utilization. This project addresses the issue of local utilization of renewable energy sources through large-scale hydrogen-electricity coupled energy storage. It is based on the \"electricity-hydrogen-electricity\" (P2P) conversion process, and integrates technologies such as wind and solar power generation, energy storage, hydrogen production, hydrogen-powered electricity generation, and coordinated control of multiple energy sources. This enables flexible two-way conversion between hydrogen energy and electric energy, thereby supporting the green supply of hydrogen energy and the high-level utilization of renewable energy sources. At the meeting, the project leader provided a detailed introduction covering aspects such as the background and objectives of the project, the tasks involved, the design of the individual systems, modeling, simulation, analysis, and verification, the development of energy management software, and the verification of key technologies. The experts listened to the presentation and reviewed the relevant materials. Following inquiries and discussions, the expert group unanimously agreed that the project passed the technical design review. The expert group believes that the technical design of this project is outstanding; it involves modeling, simulation, and verification of technologies such as the operating mechanism of hydrogen-electric coupling systems, as well as control and optimization scheduling, thereby providing effective support for the project’s technical design. The simulation verification parameters for the overall system model of this project are based on actual photovoltaic/wind power data, accurately reflecting the real-world operating conditions. At the same time, the physical technology verification system for this project has clear objectives and the necessary foundational conditions are in place. The expert group recommended that the project team refine the verification plan and implement it as soon as possible, in order to accelerate the acquisition of the core technologies related to energy regulation strategies for off-grid hydrogen-electric coupled energy storage systems. The experts present affirmed the work carried out by the project team, stating that \"off-grid hydrogen-electricity coupled energy storage\" meets the needs of the new energy industry as well as the development of Lanxi Group’s hydrogen energy sector. By extending, supplementing, and strengthening relevant industrial chains, this approach facilitates the integrated development of wind, solar, hydrogen, and energy storage technologies. It enables the production of green hydrogen in a carbon-free manner, and its key core technologies can be applied in large-scale hydrogen production and the utilization of renewable energy. Such technologies enhance the competitiveness of products in the hydrogen energy storage industry chain, including hydrogen production devices, by offering more stable performance, a higher rate of renewable energy utilization, and greater flexibility in configuration, thereby increasing the technical value of these products. Next, Lansi Research Institute will continue to strengthen research and development in hydrogen-electric coupled energy storage integration technologies as well as their market promotion. It will seize the opportunities presented by the development of hydrogen (ammonia) energy storage industries, take into account the needs of various applications in the field of new energy, explore the best investment options under different scenarios, and promote the industrialization of such projects, thereby contributing to the group’s development in the new energy sector.
