Hydrogen is currently enjoying a renewed and widespread momentum in many national and international climate strategies. This review paper is focused on analysing the challenges and opportunities that are related to green and blue hydrogen, which are at the basis of different perspectives of a potential hydrogen society. While many governments and private companies are putting significant resources on the development of hydrogen technologies, there still remains a high number of unsolved issues, including technical challenges, economic and geopolitical implications. The hydrogen supply chain includes a large number of steps, resulting in additional energy losses, and while much focus is put on hydrogen generation costs, its transport and storage should not be neglected. A low-carbon hydrogen economy offers promising opportunities not only to fight climate change, but also to enhance energy security and develop local industries in many countries. However, to face the huge challenges of a transition towards a zero-carbon energy system, all available technologies should be allowed to contribute based on measurable indicators, which require a strong international consensus based on transparent standards and targets.

“…The current technology for underground storage of hydrogen uses the same types of reservoirs as for natural gas. Depleted gas fields, aquifers or salt caverns are considered as possible storage sites (Bai et al, 2014). Although gas storage is a key step in the hydrogen economy (Crotogino et al, 2010), the loss of hydrogen through chemical reactions with confining rocks is one of the major geochemical and operational challenges (Bourgeois et al, 1979;Carden and Paterson, 1979;Foh et al, 1979;Lord, 2009).…”

“…Underground Hydrogen Storage (UHS) is much less studied than the underground natural gas storage, therefore in most existing hydrogen storage sites, the pressure does not exceed more or less than 150 bar. This is explained by its high mobility due to its small size [10], as well as its high reactivity (redox reactions) by possibly participating in certain microbial processes: sulfate-reduction, methanogenesis, acetogenesis, and iron-reduction [11,12]. Most of these types of reactions can take place in the aqueous medium, i.e.…”

In the context of Underground Hydrogen Storage (UHS), the stored gas is in direct contact with brine (residual brine from the cavern or formation water of deep aquifers). Therefore, knowledge of the phase equilibria (solubility of hydrogen in brine and water content in the hydrogen-rich phase) in the geological reservoir is necessary for the study of hydrogen mobility and reactivity, as well as the control, monitoring and optimization of the storage. The absence of measured data of high-pressure H2 solubility in brine has recently led scientists to develop predictive models or to generate pseudo-data using molecular simulation. However, experimental measurements are needed for model evaluation and validation. In this work, an experimental apparatus based on the "static-analytic" method developed and used in our previous work for the measurement of gas solubility in brine was used. New solubility data of H2 in H2O+NaCl were measured more or less under the geological conditions of the storage, at temperatures between 323 and 373 K, NaCl molalities between 0 and 5m, and pressures up to 230 bar. These data were used to parameterize and evaluate three models (Geochemical, SW, and e-PR-CPA models) tested in this work. Solubility and water content tables were generated by the e-PR-CPA model, as well as a simple formulation (Setschenow-type relationship) for quick and accurate calculations (in the fitting range) of H2 solubility in water and brine was proposed. Finally, the developed models estimate very well the water content in hydrogen-rich phase and capture and calculate precisely the salting-out effect on H2 solubility.
