Underground gas storage

Underground gas storage (UGS) is one of the important topics of the 21st century, in particular to ensure the security of energy supply in Europe. Two kinds of gas storage can be distinguished: UGS in salt caverns and storage of natural gas in the pore space of former hydrocarbon reservoir rocks, namely sandstone. In the latter case a tight caprock - shale, clay-, silt- or marlstone - has to prevent leakage of the UGS. Gesteinslabor is specialised in the investigation of the geomechanical properties of these rocks: their strength as well as permeability and threshold pressure. Together with information about the in situ stresses (gained by RACOS®) Gesteinslabor is able to develop a geomechanical model for the UGS.

So far Gesteinslabor did research about numerous pore space UGS in Europe's most important gas storage regions, namely the North German, the Molasse, the Vienna and the Pannonian basins. All our investigations supported the installation of save and secure UGS.

In September 2019 the Swiss National Cooperative for the Disposal of Radioactive Waste (NAGRA) commisioned Gesteinslabor with UCS, Brazilian and triaxial tests on neighbouring rocks of the Opalinus Clay - the rock which will host Switzerland's future facilities for nuclear waste disposal.

Gesteinslabor receives funding from BMWi for the development of a new test rig. With this funding, our company will open up a new business field in renewable energies by implementing an innovative technology to determine the capillary threshold pressure with hydrogen on cap rock of underground gas storage facilities.
