Determination of mechanical parameters of salts in the cyclic load processes corresponding to the operation of a storage cavern for hydrogen

Abstract

The paper describes the results of laboratory tests of the strength of salt samples made as part of the HESTOR project in order to determine the mechanical parameters of salt. The tests were carried out using an Autolab 2000 apparatus which allows to simulate any load cycles. The tests were made by simulating the operation of the hydrogen storage cavern. In order to observe the differences in salt behavior depending on the sample medium being stored during the test, gases were supplied: nitrogen, as an analogue of natural gas, and helium as a hydrogen analogue.
