• Long-duration energy storage (LDES) is vital for integrating renewable energy into the grid, yet scaling up these technologies remains challenging.
• We are developing a significant advanced-CAES facility in Ontario, highlighting advancements in energy storage solutions like compressed air and thermal energy systems.
• Despite the potential of LDES to revolutionize energy systems with technologies like our compressed air storage or Form Energy’s iron-air batteries, the sector faces hurdles in market adoption and financing.
• Utilities are cautious, often prioritizing grid stability over new technologies, while innovations in areas like thermal and flow batteries show promise but require significant investment and commercial validation to achieve large-scale deployment.
