Application of Carbon Dioxide Energy Storage Technology Based on New Energy Atmospheric Pressure Flexible Gas Film Storage Bin: Take Xinjiang Region as a Case

China's renewable energy sector has shifted from rapid capacity expansion to addressing volatility and ensuring stable energy supply. Against this backdrop, new energy storage methods have significant market potential. This paper explores the use of low-pressure flexible gas membrane storage chambers for CO2 gas storage, integrated with an energy storage system to store power generated by renewable sources. By leveraging photovoltaic power generation, carbon capture and storage (CCS), and C02 phase conversion technology, the study examines the application value of this approach in the Xinjiang region. The proposed solution addresses the intermittent and volatile nature of renewable energy, achieving stable grid supply and meeting the requirements for flexible grid regulation. This provides a strategic pathway for advancing the construction of a comprehensive new energy generation and storage system.
