Abstract Transition to cleaner energy sources is crucial for reducing carbon emissions to zero. Among these new clean energy types, there is a growing awareness of the potential for naturally occurring geologic hydrogen (H2) as a primary energy resource that can be readily introduced into the existing energy supply. It is anticipated that geophysics will play a critical role in such endeavors. There are two major different types of geologic H2. One is natural H2 (referred to as gold H2), which is primarily accumulating naturally in reservoirs in certain geological setting; and the other is stimulated H2 (referred to as orange H2), which is produced artificially from source rocks through chemical and physical stimulations. We will first introduce geophysics in geologic H2 in comparison and contrast to the scenarios of blue and green H2. We will then discuss the significance of geophysics in both natural H2 and stimulated H2 in term of both exploration and monitoring tools. Comparing and contrasting the current geophysical tools in hydrocarbon exploration and production, we envision the innovative geophysical technologies and strategies for geologic H2 resources based on our current understanding of both natural and stimulated geologic hydrogen systems. The strategies for H2 exploration will involve a shift from reservoir- to source rock-centered approaches. Last, we believe that the geophysical methods including integration of multi-geophysics, efficient data acquisition, and machine learning in geologic H2 could be potentially provide sufficient new directions and significant opportunities to pursue research for the next one or two decades.

Geologic hydrogen: An emerging role of mining geophysics in new energy exploration
Geologic hydrogen has emerged as a potentially transformational energy resource in the quest to transition to net-zero emission energy supplies. If realized, this new form of energy resource could circumvent the insurmountable challenge of finding and producing enough metals and critical minerals to meet the demands of clean energy by year 2025. The technical challenge to finding geologic hydrogen requires the reconfiguration and recombination of two major branches of exploration geophysics, namely, the mineral exploration and oil and gas exploration and, therefore, could provide unprecedented opportunities for the exploration geophysicists from both energy section and mineral sectors and the Society of Exploration Geophysicist in general. In this presentation, we briefly review geologic hydrogen as an energy resource and the need for integrated exploration strategies to find it, and discuss the role of hard rock mineral exploration geophysics in a source rock-center strategy for geologic hydrogen exploration. The latter could provide exploration geophysicists a new cycle of opportunities and new space of applying our expertise, albeit in reconfigured and recombined modes.

Abstract Geologic hydrogen has emerged as a primary energy source, drawing growing interest from the scientific community and the energy sector. One of the primary geochemical mechanisms for natural hydrogen generation is serpentinization, which is the hydration of mafic and ultramafic rocks. The United Arab Emirates (UAE) is home to one of the largest ophiolite blocks in the world, making it a promising area for geologic hydrogen exploration. In this study, we apply magnetotelluric (MT) phase tensor analysis to detect electrical anisotropy associated with serpentinization in the mantle peridotite sequence. The alignment of olivine crystals and hydrous minerals such as serpentine impart electrical anisotropy to these rocks. Current approaches for detecting serpentinization have primarily focused on changes in bulk physical properties, often overlooking the directional dependencies and complexities introduced by anisotropy. In this research, we introduce a novel geophysical framework based on the phase tensors, to identify serpentinized zones within source rocks in geologic hydrogen systems and possibly identify potential hydrogen-bearing zones. Using MT field data from the UAE, we demonstrate that phase tensor analysis effectively identifies anisotropic conductivity zones associated with serpentinization. The MT phase tensor approach we propose can support assessment of geologic hydrogen generation and its lifecycle.more » « less

The Mindat open data service, encompassing data from over 6,000 mineral species and 400,000 localities, has big potential to support the work of mineral exploration by providing insights into mineral associations, paragenetic modes, and visual network analyses through labeled photographs. These tools enable geologists to identify indicator minerals, understand mineral formation sequences, and visually assess mineral assemblages. Mineral association analysis highlights minerals commonly found together, while paragenetic studies offer clues to formation environments. Visual networks of mineral relationships provide rapid identification references. Together, these resources raise new opportunities to enable data-driven strategies that eventually enhance the efficiency and accuracy of mineral exploration.more » « less

Fantini, Jacques; Brack, André (Ed.)We provide new support for habitable microenvironments in the near-subsurface of Mars, hosted in Fe- and Mg-rich rock units, and present a list of minerals that can serve as indicators of specific water–rock reactions in recent geologic paleohabitats for follow-on study. We modeled, using a thermodynamic basis without selective phase suppression, the reactions of published Martian meteorites and Jezero Crater igneous rock compositions and reasonable planetary waters (saline, alkaline waters) using Geochemist’s Workbench Ver. 12.0. Solid-phase inputs were meteorite compositions for ALH 77005, Nakhla, and Chassigny, and two rock units from the Mars 2020 Perseverance rover sites, Máaz and Séítah. Six plausible Martian groundwater types [NaClO4, Mg(ClO4)2, Ca(ClO4)2, Mg-Na2(ClO4)2, Ca-Na2(ClO4)2, Mg-Ca(ClO4)2] and a unique Mars soil-water analog solution (dilute saline solution) named “Rosy Red”, related to the Phoenix Lander mission, were the aqueous-phase inputs. Geophysical conditions were tuned to near-subsurface Mars (100 °C or 373.15 K, associated with residual heat from a magmatic system, impact event, or a concentration of radionuclides, and 101.3 kPa, similar to <10 m depth). Mineral products were dominated by phyllosilicates such as serpentine-group minerals in most reaction paths, but differed in some important indicator minerals. Modeled products varied in physicochemical properties (pH, Eh, conductivity), major ion activities, and related gas fugacities, with different ecological implications. The microbial habitability of pore spaces in subsurface groundwater percolation systems was interrogated at equilibrium in a thermodynamic framework, based on Gibbs Free Energy Minimization. Models run with the Chassigny meteorite produced the overall highest H2 fugacity. Models reliant on the Rosy Red soil-water analog produced the highest sustained CH4 fugacity (maximum values observed for reactant ALH 77005). In general, Chassigny meteorite protoliths produced the best yield regarding Gibbs Free Energy, from an astrobiological perspective. Occurrences of serpentine and saponite across models are key: these minerals have been observed using CRISM spectral data, and their formation via serpentinization would be consistent with geologically recent-past H2 and CH4 production and sustained energy sources for microbial life. We list index minerals to be used as diagnostic for paleo water–rock models that could have supported geologically recent-past microbial activity, and suggest their application as criteria for future astrobiology study-site selections.more » « less

Abstract Ice and other mineral cements in Mars' shallow subsurface affect the mechanical properties of the shallow crust, the geologic processes that shape the planet's surface, and the search for past or extant Martian life. Cements increase seismic velocities. We use rock physics models to infer cement properties from seismic velocities. Model results confirm that the upper 300 m of Mars beneath InSight is most likely composed of sediments and fractured basalts. Grains within sediment layers are unlikely to be cemented by ice or other mineral cements. Hence, any existing cements are nodular or formed away from grain contacts. Fractures within the basalt layers could be filled with gas, 2% mineral cement and 98% gas, and no more than 20% ice. Thus, no ice‐ or liquid water‐saturated layers likely exist within the upper 300 m beneath InSight. Any past cement at grain contacts has likely been broken by impacts or marsquakes.more » « less
