Streszczenie
This article investigates the feasibility of large-scale underground hydrogen storage for renewable energy,
emphasizing the influence of local geological conditions, gas composition, and salt cavern depth. The theoretical part explains
the need for energy storage, referring to regulations and the inconsistencies in energy consumption and renewable energy
production. It presents the advantages and disadvantages of various storage technologies, focusing on salt caverns.
The practical analysis focuses on the Kosakowo Underground Gas Storage Facility, evaluating the impact of cavern depth and
gas composition on storage capacity. Findings show deeper caverns improve capacity, but a higher hydrogen concentration in
methane-hydrogen mixtures reduces efficiency. Tabular and graphical data illustrate technological and economic challenges,
including hydrogen's low volumetric energy density and stringent safety requirements.
The article concludes that despite hydrogen's promise as a green fuel, its physical properties and high costs constrain its
effectiveness for long-term energy storage.
