Hydrogen is being regarded as a primary vector in the energy transition process towards less polluted planet. The tremendous and increasing demands necessitate finding large-scale storage techniques. Underground salt caverns seem to be promising. Nevertheless, fast solicitations (thermal mechanical) of these caverns, reply demands, imply damage ambient rock salt. There general scientific ambigu...

Abstract Hydrogen is expected to play a key role in future climate-neutral economy by decarbonizing ‘hard abate’ sectors, and importantly act as an energy carrier balance intermittent renewable production, which, if stored, could be used address grid-scale demands. It evident that for unlocking the vast potential of hydrogen technologies, large-scale storage with capability fast cyclic operatio...

The article presents a method of forecasting the deformation land surface over large fields underground gas storage facilities located in salt caverns. solution allows for taking into account many parameters characterising operation facilities, such as cavern processes (leaching, enlargement, operational, etc.), their depth, distribution, diameter, shape, and others. advantage applied other ava...

When storing gas in a salt cavern, it occupies most of the excavated volume, but lower part cavern inevitably contains residual brine, contact with gas. The design hydrogen and compressed air storage caverns requires to have thermodynamic model able accurately predict both phase properties such as densities, equilibrium (gas solubility water content vapour phase). This work proposes parameteriz...

Salt deposits are commonly regarded as ideal hosts for geologic energy reservoirs. Underground cavern construction-induced damage in salt is reduced by self-healing. Thus, studying the influencing factors on such healing processes is important. This research uses ultrasonic technology to monitor the longitudinal wave velocity variations of stress-damaged rock salts during self-recovery experime...

In this paper we present an algorithm for the valuation and optimal operation of natural gas storage facilities. Real options theory is used to derive nonlinear partial-integro-differential equations (PIDEs) for the valuation and optimal operating strategies. The equations are designed to incorporate a wide class of spot price models that can exhibit the same time-dependent, mean-reverting dyna...

Hydrogen pipeline systems offer an economical means of storing and transporting energy in the form of hydrogen gas. Pipelines can be used to transport hydrogen that has been generated at solar and wind farms to and from salt cavern storage locations. In addition, pipeline transportation systems will be essential before widespread hydrogen fuel cell vehicle technology becomes a reality. Since hy...
