【Ten Years of Rapid Development in Chemical Engineering Equipment】The First Integrated Project for the Combined Use of Photovoltaic Energy, Energy Storage, Hydrogen, and Heat in the Northwest Region from 2014 to 2023

Thread Content

Ten years of rapid development in chemical technology – praise for China’s prosperity and strength. This is just a starting point; more participation will make things even more lively. HaiChuan becomes even better with your involvement; we welcome everyone to join in the forum discussions. The fragrance of rice flowers in August ----------------------------------------- In August 2023, the comprehensive application demonstration project for solar energy, storage, hydrogen production, and heat utilization in Zhangye City, Gansu Province, was completed, and it now has the capability to produce hydrogen. This is the first integrated project in northwestern China that combines the use of light, energy storage, hydrogen, and heat. It will store any excess new energy generated, and explore various applications for green hydrogen in the Hexi Corridor, an area with abundant wind and solar resources. The project is funded and constructed by China Power Engineering Consulting Group Co., Ltd. and China Energy Engineering Group Corporation, both subsidiaries of China Energy Engineering Group Co., Ltd. (hereinafter referred to as \"China Energy Engineering\"). The total investment amounts to approximately 4.4 billion RMB, and the construction includes 1,000 megawatts of photovoltaic power generation, as well as facilities for energy storage, hydrogen production, and comprehensive refueling stations. Deng Qiguo, the person in charge of the Zhangye Integrated Application Demonstration Project for Light, Energy Storage, Hydrogen, and Heat, told reporters from China News Service and China News Network on the 11th that in recent years, industries such as wind and solar energy in China have developed rapidly. However, due to the instability of these sources of energy, which depend on weather conditions to generate power, there is a problem: electricity generated during the day’s low-demand periods cannot be supplied, while electricity cannot be generated during the night’s high-demand periods. This project aims to make use of any excess electricity generated. “The electricity generated during the day can be stored and supplied again during peak usage times at night; any excess electricity can also be used to produce hydrogen through water electrolysis. ”Deng Qiguo explained that the principle of photoelectric energy storage is to use an energy storage battery the size of a container as a \"super power bank\"; it can not only supply electricity on-site but also be moved to places such as hospitals and sports venues to provide emergency power supply, at a cost lower than market electricity rates. Zhangye City is located in the \"waist\" area of the Hexi Corridor, where wind and solar energy resources are abundant. It is part of China’s clean energy base in the Hexi Corridor, as well as a key city for electricity output in Gansu Province. It is also included in the key planning areas for large-scale wind and solar power generation projects in China’s \"desert and barren land\" regions. Currently, the area has been designated as a pilot demonstration zone for green hydrogen production and comprehensive utilization in Gansu Province.
