Renewable energy sources like solar and wind are crucial for a carbon-free future, but storing their excess energy remains a challenge. Compressed air energy storage (CAES) is emerging as a promising solution, potentially offering a cheaper and more sustainable alternative to batteries.
Conventional CAES systems have faced limitations due to geographic requirements and thermal energy loss issues. However, we are pioneering “Advanced” CAES, utilizing hard-rock caverns and water reservoirs for compressed air storage. This innovative approach improves efficiency, reduces space requirements, and allows deployment near high-demand areas like cities.
Our technology can recover about 60% of stored electricity, significantly better than traditional CAES systems. With operational facilities in Ontario and plans for larger projects worldwide, our CAES could play a pivotal role in transitioning to 100% renewable energy
