With LAGI 2016 focusing on a coastal site, we thought it would be interesting to highlight this project in Toronto that is demonstrating a new kind of compressed air storage.
The project maintains a small ecological footprint by using horizontal drilling techniques to connect to deep water where the pressure is equal to that of the air being stored.
The new technology being tested by Hydrostor in Toronto estimates 80% efficiency (energy extracted/energy stored) and can be applied to any coastal condition to help with intermittency (solar & wind), load balancing, reserve capacity, and peak-shaving needs of the regional electrical grid.
