EN The issue of gas permeability of porous beds is important for the development of a new generation of clean energy sources, especially in the context of unconventional energy storage. Detailed experimental studies were carried out to demonstrate the gas permeability of porous materials: in situ karbonizat and natural and synthetic pumice. The measure of gas permeability was the volumetric gas flow velocity resulting from the permissible pressure difference forcing the gas flow in a given axis (X, Y, Z) on a sample of a cube-shaped porous material. A novelty is the indication of correlation with selected materials exhibiting features of unconventional energy storage. Assessment of the gas permeability coefficient for selected material features shows an increasing trend for epoxy resin, dacite, in situ carbonizate and pumice. On the other hand, for carbonate rocks, mudstones and shales, there is a decrease in gas permeability. The indicated porous materials can be storage tanks of unconventional energy carriers. In an innovative way, a material (halloysite) was indicated that has the ability to store and be a source of transport in the form of a cylindrical model (nanotube) for future implementation of isotropic features of porous materials.
