Idaho gotya beat!

I lived in Idaho, I know low electric rates when I had them lol

The Kentucky Geological Survey is doing A LOT of research in CO2 
sequestering. We have more coal powered plants around here than you can 
shake a stick at. We also have the cheapest electricity in the country.

DuPont Comapny had a HCl injection well in west Louisville associated with 
their chemical plant. The pumped it down about 5000 feet into the Cambrian 
Knox dolomite if I recall correctly. It has dissolved out a chamber about 
2500 feet in diameter which is now filled with compressed CO2 and other 
byproducts. About 20 years ago (maybe more) the well head broke and a CO2 
eruption occurred. They called in Red Adair the oil fire guru at the time 
who capped the well. No problems since then.
