Based on the formal and legal regulations, the need to increase the capacity of cavern underground gas storage in Poland is demonstrated. The author raised the problem of country's energy security, which is partly based on intervention reserves of energy carriers. A description of the state of actual storage capacities and strategic reserves of natural gas in Poland is presented, and the level of reserves is assessed based on applicable law. Focusing on the advantages of salt deposits in the context of underground gas storage, the author presents safe conditions for underground gas storage and the possible location of cavern underground gas storage in two prospective salt deposits: the Damasławek salt dome and the layer salt deposit of the Fore-Sudetic Monocline. The article draws attention to the complexity of the issue of geomechanical stability of caverns for underground gas storage, taking into account the type of deposit (layer/dome).

The article describes the subject of underground hydrogen storage in the context of energy storage using hydrogen as a carrier, and shows its role in the Polish energy policy. The review of the most recent papers was performed to provide the information about hydrogen properties and options for underground hydrogen storage (salt caverns, depleted hydrocarbons fields, deep aquifers) in Poland. Analysis of the literature indicates small practical experiences in the underground hydrogen storage. The behaviour of underground-stored hydrogen is more complex than expected. Previous results indicate that this option may in future become the preferred solution for storing excess electricity related to the irregular supply from renewable sources. Geological formations can provide the possibility of storing energy on a medium- and long-term time scale. Knowledge of the underground storage of carbon dioxide and other gases will be useful for searching ofsites for underground storage of this gas. Due to the planned increasing share of renewable energy in electricity production in Poland, the issue of underground hydrogen storage will become increasingly relevant.

Poland has the limited gas and oil resources. Main hydrocarbons supplies are delivered to Poland mostly from Russia by oil and gas pipelines. Very large length of these pipelines as well as the local considerable wearing of devices induces the necessity of reserves storage. Geological conditions in Poland and a considerable quantity of exhausted gas deposits enabling in nearest years to the construction of underground gas storages (UGS) suggest the new investments in this sector of petroleum industry. Capacity amount of present active UGS is 1.58 x 10exp.9 mexp.3 but after finalizing of storages their volume will achieve 2.8 x 10exp.9 mexp.3. Special attention is paid to the Wierzchowice UGS (the biggest one in Poland) and to caverns leaching within the Zechstein salts cavern underground gas storages (CUGS) Mogilno and Kosakowo. Reservoirs of cavern type (expensive under construction) are a very efficient, modern source of gas system supply, particularly in periods of the seasonal demand fluctuations for gas - a very high during the winter season in the central and the northern Europe. Only caverns in salts allow to store both the gas and the liquid hydrocarbons. Construction of the UGS refers mostly to exhausted gas fields, discovered and exploited by the Polish Oil and Gas Company. Experience and capital of the state company located it as a leader in Poland in the field of construction and exploitation of underground storages. Their construction has the minimum influence on the environment. Utilization of exhausted hydrocarbons deposits (often with the existing mining infrastructure) is not almost at all troublesome for a local population and the environment and it offers considerable practical and economic benefits. The economical boom in the oil and gas market during last years creates new challenges for construction and exploitation of hydrocarbons underground storages.
