Chris Schimp has patented this vertical method of storing compressed gas.
Standard HP well casing is used creating a small footprint area where multiple units can be placed close to each other and piped together. Pipe diameter and well depth govern the storage capacity.
The heat of compression is dissipated by the earth below. Depending upon the number of capacitors, the cost to create CNG storage capacity can be extremely less exprensive than above ground storage.
This unique storage idea not only can be used as a buffer for CNG fueling stations but for supply storage at factories, hospitals, wherever....
