A pressurized gas storage system includes an outer shell having an inner and outer surface. The inner surface defines an inner volume for holding a pressurized gas. A first electrically conductive layer is attached to the outer shell. An inner liner is disposed over the inner surface. A second electrically conductive layer is attached to the inner liner. A capacitance meter measures the capacitance between the first and second electrically conductive layers wherein a change in capacitance indicates buckling in the storage system.
