What goes into building and burying large scale underground structures like those air caverns?
- mschuster91 5y agoNot much, technologically this is a conventional mine project, only that you mine air volume instead of rock and have to take care of the cavern being reasonably airtight afterwards.

- fastball 5y agoThe same company has actually done this[1] with the city of Toronto. [1] https://www.youtube.com/watch?v=GicQwXbNnv0 https://www.youtube.com/watch?v=GicQwXbNnv0
- nkurz 5y agoThe video is from 2015, and says it was a 2 year pilot project. Do you know if there are there any updates on how the project went? Is it still operational? Did they build any more?
- fastball 5y agoNot sure, this is the page on the companies website: https://www.hydrostor.ca/toronto-a-caes-facility/ https://www.hydrostor.ca/toronto-a-caes-facility/
- buryat 5y agoyou don't have to build those caverns as they already exist and we have extracted gas and liquids from them, also the volume should be already known as we know how much we pumped out (unless it's an old site)
- srcmap 5y agoIsn't the complexities related to making those caverns air and water tight for long period of time for long term energy storage requirements?
