6 FAQs about [Shale gas maximum energy storage]
What factors affect adsorption capacity and gas-bearing capacity of shale?
All of these factors will affect the adsorption capacity and gas-bearing capacity of shale, especially the competitive adsorption mechanism and influence of water and N 2, and require further attention and research.
Can hydraulic fracturing provide underground energy storage in shale formations?
In this study, we propose a new underground energy storage technology based on hydraulic fracturing in shale formations (As shown in ). This patented technology utilizes underground artificial fractures created by hydraulic fracturing to store potential energy.
Why is shale gas important to China?
Under the broad prospect of green and low-carbon energy, shale gas will make a crucial contribution to meeting clean energy demand, which is particularly significant for China's energy supply and transformation.
What controls the gas content of shale?
The gas content of shale is controlled by a combination of its geological properties (OM abundance, kerogen type, thermal maturity, mineral composition, diagenesis), pore fluid properties (water, CH 4, non-hydrocarbon gases), and geological conditions (temperature, pressure, preservation conditions).
What factors affect shale gas exploration potential?
Among many factors affecting shale gas exploration potential, the gas-bearing properties of shale (quantity, storage state, composition) and their controlling factors are the essential research attracting wide attention in the academic community.
Why is shale less adsorption capacity than gas-solid?
Since the interaction intensity of gas-liquid is much lower than the force of gas-solid, it would also reduce the adsorption capacity of shale to CH 4 (Li et al., 2016a; Hu et al., 2018c) (Fig. 5 b). With the increase of moisture content, the accessible pores are decomposed into many invalid pores by water molecules.
