“…In the case of town gas storage in Beynes (France) 48 , it has been argued that abiotic pyrite reduction resulted in H2S production, however, it should be noted that H2S generation may be inhibited by the presence of carbonate minerals within the reservoir 45,49 . As the hydrocarbon industry has decades of experience of safely producing H2S-rich natural gas 50,51 , this would be a surmountable, though costly, side-effect of hydrogen storage. Experimental studies on reservoir sandstones under subsurface conditions (T = 40-100°C, P = 10-20 MPa) show dissolution of carbonate and sulphate cements, leading to an increase in porosity during hydrogen exposure 52 .…”

“…In situ combustion of heavy oil emits significant amounts of CO 2 that carbonizes the cement paste (see Figure ). , Figure shows the compressive strength of the cement paste carbonized for 7, 14, and 28 days under HCC conditions. It can be seen that, with increasing carbonation time, the compressive strength obviously increased.…”

“…However, there are a few publications on the effect of CETS and ETS conditions on the chemical structure, microstructure, and properties of cement paste. Additionally, it has been reported in the literature − that when cement paste was exposed to a high concentration of CO 2 , CO 2 , or CO 3 2– diffused into the cracks and pores of the cement paste, Ca(OH) 2 and C–S–H were carbonized to form both crystalline and amorphous calcium carbonate. − Because the volume of CaCO 3 is larger than that of the original Ca(OH) 2 in the cement paste, the growth of CaCO 3 increases the internal stress of the cement paste, producing cracks and reducing the mechanical properties of the cement paste. − However, in these publications, the cement pastes did not experience curing under the CETS and ETS conditions. It is thus difficult to explain the carbonation behavior and mechanism of the cement paste after CETS and ETS curing in the heavy oil thermal recovery process. ,, …”

In a heavy oil thermal recovery well, cement paste experiences the cyclic elevated temperature and steam of steam stimulation, the elevated temperature and steam of steam driving, and the high-concentration CO2 (HCC) of in situ combustion conditions in sequence. To understand the effects of different conditions of heavy oil thermal recovery wells on the properties and microstructure of the cement paste, this paper investigated the influence of the cyclic elevated temperature, elevated temperature, and high-concentration CO2 conditions on the compressive strength of the cement paste. Then, low-field nuclear magnetic resonance, scanning electron microscopy, and X-ray diffraction were used to test the pore structure, microstructure, and crystal type of the cement paste cured under different conditions. Experimental results showed that the elevated temperature curing loosened the microstructure of the cement paste and increased its pore size and porosity, resulting in reducing the compressive strength to 21.04 MPa, compared with that of the cement paste at cyclic elevated temperature. For the cement paste cured under high-concentration CO2 conditions, the calcium hydroxide and calcium-silicate-hydrate reacted with CO2 to generate granular vaterite, aragonite, and calcite in the pores and cracks, which repaired the cement paste by reducing the porosity and pore size of the cement paste and increasing its compressive strength. When the carbonation time increased to 28 days, the cement paste was completely carbonized, and the compressive strength of the cement paste increased by approximately 169%, compared with that of the cement paste cured at an elevated temperature.

The energy transition is the pathway to transform the global economy away from its current dependence on fossil fuels towards net zero carbon emissions. This requires the rapid and large-scale deployment of renewable energy. However, most renewables, such as wind and solar, are intermittent and hence generation and demand do not necessarily match. One way to overcome this problem is to use excess renewable power to generate hydrogen by electrolysis, which is used as an energy store, and then consumed in fuel cells, or burnt in generators and boilers on demand, much as is presently done with natural gas, but with zero emissions. Using hydrogen in this way necessitates large-scale storage: the most practical manner to do this is deep underground in salt caverns, or porous rock, as currently implemented for natural gas and carbon dioxide. This paper reviews the concepts, and challenges of underground hydrogen storage. As well as summarizing the state-of-theart, with reference to current and proposed storage projects, suggestions are made for future work and gaps in our current understanding are highlighted. The role of hydrogen in the energy transition and storage methods are described in detail. Hydrogen flow and its fate in the subsurface are reviewed, emphasizing the unique challenges compared to other types of gas storage. In addition, site selection criteria are considered in the light of current field experience.
