Liquid Air Energy Storage Project in St. Clair Township
Project Summary
NRStor is proposing to develop a liquid-air energy storage (LAES) project in St. Clair Township. This innovative technology charges by using ambient air, which is cooled, becoming a liquid, and stored in large, insulated tanks on site. To provide electricity back to the grid, the liquid air is warmed to become a gas again, where it runs through a turbine, returning the electricity to the grid while the air is vented back to the atmosphere. This allows energy to be stored for much longer than typical battery energy storage systems.
The project will provide capacity services to the Ontario grid using emissions-free liquid air energy storage technology, helping enable affordable and reliable electricity province-wide.
