Liquid nitrogen anyone? Also there is a project in Toronto that stores the compressed air in balloons submerged under lake ontario. These salt caverns sound interesting though. How does it compare to the economics of storing hydrocarbons in the same space over the course of a year or 10? Which fuel source would be cheaper in the long run?
Thanks for watching this talk. The presenter may be able to provide info on their calculator. It may be possible to reach him on social media, such as linkedin.
Above ground case using 40 foot iso containers should a possibility. I would like to build a 1MW plant backed by solar in Barbados using such technology.
But why can’t you take this compressed air to spin a turbine through something like a pneumatic motor? Why are you using natural gas to heat it, then to create a turbo effect while mixing it with natural gas to combust again? Pneumatic tools run off just the air I wonder why a pneumatic motor to turn the turbine is not discussed?
Hi Anthony, I'm not the presenter but may be able to answer your question. Electricity is being generated by expanding air driving the turbine. The rapidly expanding air absorbs heat. Without an input of heat into the system the constant expansion of the air would lead to freezing temperatures in the turbo machinery, icing, and failure of the system. Burning natural gas is one way to add heat into the system, another way is to use stored heat produced when the air is compressed, as discussed by another presenter: ua-cam.com/video/TRdn_C2WKqc/v-deo.html
@@ogsrlibrary ok thanks for the response. I guess I’m just envisioning the air going to drive a pneumatic turbine like a NASCAR pit crews pneumatic drills. Or anyone who has used pneumococcal tools. They have more torque, higher rpm and more power

What is the round trip efficiency of the power in %
Way behind the Brits. They have a major complex setup near Manchester, UK.
Can I find your volume calculator online?
Can you please upload your calculator? or is it not public?

At What Pressure? I will suggest you stick to gas filling station standards and bury same tanks not containers.

Great Stuff very clear and concise. 👍 I hit u up on LinkedIn
Good
