Hydrogen storage in inactive horizontal shale gas wells: Techno-economic analysis for Haynesville shale

Perspectives and prospects of underground hydrogen storage and natural hydrogen

“…They noted that the integration of UHS technology with electrolytic hydrogen production could foster power production and distribution systems in Germany. 146 Recently, Singh 144 performed a comparative techno-economic analysis of hydrogen storage in inactive horizontal shale gas wells and underground storage facilities (Fig. 8b-e).…”

“…The author stated that the capital expenditure of hydrogen storage in shale lateral wells is dependent on the existing surface facilities such as the gas compressor station at the wellpad. 144 Wu et al 147 presented a technoeconomic assessment framework for hydrogen storage by considering four different case studies including the storage of hydrogen in an underground salt cavern for longer periods and fuel cell for regeneration. The other scenarios considered by the authors includes the direct injection of hydrogen into gas networks and the bulk sale as transportation fuel and industrial gas.…”

Capacity Allocation Optimization Framework for Hydrogen Integrated Energy System Considering Hydrogen Trading and Long-Term Hydrogen Storage

“…The results show that the hydrogen-containing islanded microgrid can operate stably and optimally. Hydrogen storage technology and methods are constantly improving, and hydrogen energy can be stored underground [18] , such as in the usage of shale oil mines for hydrogen storage in the United States [19] . The seasonal energy storage of hydrogen energy supports a long time, large scale and wide spatial range energy transmission characteristics are the key technology to cope with the long time break of energy supply of high percentage renewable energy system [20] .…”

H2, CO2, and CH4 Adsorption Potential of Kerogen as a Function of Pressure, Temperature, and Maturity

“…Recently, coal seams [ 26 ] and basaltic rocks [ 35 ] have also been investigated for their H 2 storage potential, albeit at a lab scale. Furthermore, shale rocks have been evaluated for large-scale CO 2 storage via adsorption trapping [ 36 , 37 , 38 ], while a recent study investigated H 2 storage in inactive shale [ 39 ]. While the idea of underground hydrogen storage (UHS) focuses on energy storage, CO 2 flooding in a medium comprised of shale and coal offers double advantages, i.e., it addresses carbon capture and storage (CCS) and enhances methane (CH 4 ) recovery [ 34 , 40 , 41 , 42 ].…”
