The Role of Green and Blue Hydrogen in the Energy Transition—A Technological and Geopolitical Perspective

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.

“…These storage aquifers can be found all around the world, but are primarily located in North America, although some also occur in Europe and the Commonwealth of Independent States (Russia, Armenia, Azerbaijan, and Belarus; Cornot-Gandolphe, 2017 ). An understanding of these ecosystems makes it possible to predict the effects of future developments on these deep aquifers depending on their use, which include (i) the sequestration of CO 2 or carbon molecules in the broad sense to address climate change; (ii) the temporary energy storage of CH 4 , H 2 or air from renewable energy sources; (iii) rare metal mining; and (iv) exploitation of their water resources ( De Silva et al, 2015 ; Flexer et al, 2018 ; Ranchou-Peyruse et al, 2019 ; Lemieux et al, 2020 ). Deep porous geological structures may present advantages such as their size, relative ubiquity and safety for gas storage, along with the proven know-how regarding their operation.…”

Microbial Diversity Under the Influence of Natural Gas Storage in a Deep Aquifer

et al. 2021

Deep aquifers (up to 2km deep) contain massive volumes of water harboring large and diverse microbial communities at high pressure. Aquifers are home to microbial ecosystems that participate in physicochemical balances. These microorganisms can positively or negatively interfere with subsurface (i) energy storage (CH4 and H2), (ii) CO2 sequestration; and (iii) resource (water, rare metals) exploitation. The aquifer studied here (720m deep, 37°C, 88bar) is naturally oligotrophic, with a total organic carbon content of <1mg.L−1 and a phosphate content of 0.02mg.L−1. The influence of natural gas storage locally generates different pressures and formation water displacements, but it also releases organic molecules such as monoaromatic hydrocarbons at the gas/water interface. The hydrocarbon biodegradation ability of the indigenous microbial community was evaluated in this work. The in situ microbial community was dominated by sulfate-reducing (e.g., Sva0485 lineage, Thermodesulfovibriona, Desulfotomaculum, Desulfomonile, and Desulfovibrio), fermentative (e.g., Peptococcaceae SCADC1_2_3, Anaerolineae lineage and Pelotomaculum), and homoacetogenic bacteria (“Candidatus Acetothermia”) with a few archaeal representatives (e.g., Methanomassiliicoccaceae, Methanobacteriaceae, and members of the Bathyarcheia class), suggesting a role of H2 in microenvironment functioning. Monoaromatic hydrocarbon biodegradation is carried out by sulfate reducers and favored by concentrated biomass and slightly acidic conditions, which suggests that biodegradation should preferably occur in biofilms present on the surfaces of aquifer rock, rather than by planktonic bacteria. A simplified bacterial community, which was able to degrade monoaromatic hydrocarbons at atmospheric pressure over several months, was selected for incubation experiments at in situ pressure (i.e., 90bar). These showed that the abundance of various bacterial genera was altered, while taxonomic diversity was mostly unchanged. The candidate phylum Acetothermia was characteristic of the community incubated at 90bar. This work suggests that even if pressures on the order of 90bar do not seem to select for obligate piezophilic organisms, modifications of the thermodynamic equilibria could favor different microbial assemblages from those observed at atmospheric pressure.

Integrated hydrogen energy systems (IHESs) have attracted extensive attention in mitigating climate problems. As a kind of large‐scale hydrogen storage device, underground hydrogen storage (UHS) can be introduced into IHES to balance the seasonal energy mismatch, while bringing challenges to optimal operation of IHES due to the complex geological structure and uncertain hydrodynamics. To address this problem, a deep deterministic policy gradient (DDPG)‐based optimal scheduling method for underground space based IHES is proposed. The energy management problem is formulated as a Markov decision process to characterize the interaction between environmental states and policy. Based on DDPG theory, the actor‐critic structure is applied to approximate deterministic policy and actor‐value function. Through policy iteration and actor‐critic network training, the operation of UHS and other energy conversion devices can be adaptively optimised, which is driven by real‐time response data instead of accurate system models. Finally, the effectiveness of the proposed optimal scheduling method and the benefits of underground space are verified through time‐domain simulations.
