1. A system for delivering volatile corrosion inhibitor (VCI) to a soil-side bottom wall of a storage tank for protecting against soil-side corrosion of the bottom wall, comprising:
an elongate carrier structure disposed within a delivery channel and extending horizontally through the soil beneath the bottom wall of the storage tank,
a transport material provided within a hollow interior of the carrier, wherein the transport material contains the VCI and is configured to adaptively release the VCI into the ground as a function of an external stimulus, wherein the transport material is configured to controllably release the VCI at a release rate, wherein the release rate of the transport material varies passively as a function of the stimulus.
