新春走基层丨甘肃：玉门关外，把西北的风存进花岗岩里

Core Viewpoint - The article discusses the innovative compressed air energy storage project in Jiuquan, Gansu, which aims to harness wind energy and convert it into a reliable power source for the Hexi Corridor, addressing the challenges of energy wastage due to grid limitations [2][18]. Project Overview - The Jiuquan project involves a 300 MW underground compressed air energy storage system, utilizing advanced technology to store energy in the form of compressed air [3][18]. - The project is located in a region characterized by strong winds and abundant sunlight, making it an ideal site for renewable energy generation [18][22]. Technical Challenges and Innovations - The project team has adopted a "six-sided engineering" approach, which includes research, design, construction, testing, and optimization, to ensure the project's success despite the lack of precedents [8][9]. - Significant technical challenges include the need for rock blasting instead of traditional earth excavation, with over 200,000 cubic meters of rock being removed [12]. - Innovations in the design of heat exchangers reduced the number from 42 to 26, which introduced new challenges in ensuring no air leakage [12][13]. Economic Impact - The project is expected to create over 100 temporary jobs during construction and contribute more than 100 million yuan in annual output value and several million in tax revenue once operational [17][18]. - It is anticipated to attract more renewable energy and storage projects to the region, fostering the development of an industrial cluster [18]. Energy Storage and Utilization - Once operational, the facility will be capable of consuming 800 million kWh of green electricity annually, providing stable power for 200,000 households for six hours daily [18][24]. - The project aims to convert previously wasted wind and solar energy into a usable form, effectively addressing the issue of energy abandonment in the region [18][24]. Historical Context and Future Vision - The article highlights the historical significance of Yumen as a pioneer in renewable energy development in Gansu, evolving from wind energy capture to energy storage solutions [22][25]. - The project symbolizes a shift in energy strategy, aiming not only to harness but also to store renewable energy effectively, ensuring its availability for future use [22][25].
