Applications of Liquid Air Energy Storage

Case:

• Guangxi 70MW/350MWh Project: An LAES plant coupled with LNG cold energy, providing grid peak shaving and frequency regulation services. Located within an LNG terminal’s processing area, occupying only 70 mu (~4.67 hectares).

• 50MW/300MWh Project: Improves system efficiency through LNG cold energy integration; technical feasibility study completed.

Multi-Energy Synergy and Grid Collaboration

• Cooling-Heating-Power Cogeneration: Stored compression heat supports power generation reheating, while LNG cold energy enables low-temperature compression for energy cascade utilization. Supplies cold energy (e.g., for cold chain logistics), thermal energy (industrial steam), and electricity to adjacent industrial zones.

• Grid Peak Shaving & Renewable Energy Integration: Stores excess wind/solar power or off-peak electricity, discharging during peak hours to alleviate grid stress (Guangxi project offers 6-hour storage capacity).
