In subsurface conditions, hydrogen can be stored in different compositions depending on the production, consumption, and conversion of energy (Panfilov, 2016): (i) pure hydrogen produced from hydrolysis or steam methane cracking is stored for fuel cell applications; (ii) hydrogen is injected into natural gas storage systems (up to 15% by volume in the final

Coal gasification, pyrolysis, and coal slurry electrolysis produce pure hydrogen suitable for various applications, including fuel cells and chemical production. Moreover, coal can also be used to store hydrogen based on rank, grade, chemical composition, maceral abundances, pore geometry, and sorption kinetics. Besides promoting net
Currently, the round-trip efficiency of hydrogen storage is still relatively low, around 30-40%, due to losses during electrolysis and transport (versus 80-90% for battery storage). The success of these energy storage stocks will also depend on the development of infrastructure for hydrogen transport and storage, which is currently underdeveloped.

In this study, the hydrogen adsorption measurements were conducted on three coal samples of varying rank at high pressures and temperatures. The hydrogen storage potential of coal was found to increase with increasing pressure and decrease with temperature irrespective of coal rank.
Minimizing energy loss & CO 2 emissions of power plants is crucial for sustainability. Plant output decreases by 4–15% for LAES/HES charging at full load for the base case. HES needs less storage volume than LAES for the same energy storage capacity (MWh). Discharging hydrogen in fuel cells performs better than co-firing in the boiler.

A full-scale hydrogen economy requires a bulk energy storage system to store the excess energy as a buffer and to fulfill the demand constantly. Hydrogen sorption capacity and diffusion behavior in coal quantify its potential to become a well storage candidate from geological formations.
Typically, for effective hydrogen storage in coal formations, there are a few important reservoir parameters determining the holding capacity and transport behaviors of the formations are expected to be clearly understood, including adsorption/desorption, diffusion, and permeability, as highlighted in purple in Fig. 1.
Hydrogen sorption capacity in coal quantifies its potential to become a well storage candidate from geological formations. In addition, the diffusivity/permeability of gas in coal seams control the effectiveness and efficiency for field implementation.
By recalling the maximum hydrogen adsorption capacities in Tab.3, it seems the depleted An and SemiAn coals rather than LvB coal and all other coals are highly potential for hydrogen storage with high adsorption capacities but relatively low injection pressure at least less than ∼ 10 MPa.
A team of Penn State scientists found that coal may represent a potential way to store hydrogen gas, much like batteries store energy for future use, addressing a major hurdle in developing a clean energy supply chain.
Even for the high-ranking An coal, the hydrogen sorption amount is approximately 3 times less than the amount of methane could be adsorbed (e.g., 0.91 mmol of methane per gram SemiAn coal at ∼ 6.53 MPa vs ∼ 0.32 mmol of hydrogen per gram An coal at ∼ 6.79 MPa).
