Hydrogen analysis by p–p scattering in geological material

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2004
It has been concluded by geologists that a significant amount of hydrogen is stored as point defects in nominally anhydrous minerals. Determination of the amount of hydrogen bound in these minerals is a step towards determining the total water content of the earth mantle as well as comprehending its internal water cycle.

HyStorPor Shows Geological Storage of Hydrogen is Possible

2023
The HyStorPor project has shown that subsurface geological storage of hydrogen is possible – an important development for the deployment of intermittent renewable energy. The £1.4m three-and-a-half year project, initiated a comprehensive, worldwide research effort on hydrogen storage, becoming a pioneer in systematically examining this field.

Reservoir Engineering Aspects of Geologic Hydrogen Storage

International Petroleum Technology Conference
Abstract Safe and effective large-scale storage of hydrogen (H2) is one of the biggest challenges of the global energy transition. The only way to realize this is storage in geological formations. The aim of this study is to address and discuss the reservoir engineering (RE) aspects of geological H2 storage (GHS).

The role of hydrogen in geological processes in the earth's interior

Solid State Ionics, 1997
Abstract Hydrogen (reported as H 2 O) affects the physical properties of silicate materials profoundly. Silicates (with Mg and Fe) dominate a significant portion of the earth's crust and mantle (0–2900 km depth). The melting point of the silicate assemblage in the upper mantle (olivine dominated) is decreased by up to 400°C at 3 GPa with the addition

Enhancing Geological Storage of Hydrogen in Subsurface Caverns

Middle East Oil, Gas and Geosciences Show (MEOS GEO)
Abstract Global hydrogen (H2) production is projected to reach ∼500 Mt/year by 2050. Large-scale storage of H2 is considered a pre-requisite for the hydrogen economy. Subsurface H2 storage including in salt caverns is seen as a viable option that supports large-scale storage and on-demand access to large-quantity energy.
