Natural Hydrogen Process
Hydrogen can be produced economically, with an overall neutral to net-negative carbon footprint, by using an engineered system that involves accessing olivine- and pyroxene-rich ores through subsurface drilling and hydraulic stimulation of mafic or ultramafic rock. This process optimizes serpentinization and carbonation reactions
Cold diydrogen (H2) extracted from rock clays and kaolins rich in aluminosilicates in the presence of sodium, water, catalyst, high temperature and used to produce bitumen very suitable for tropical climates
Produce hydrogen by converting coal bed gas and coal gas from a coal mine using the equal-air-pressure on each working face. It is suitable for geological conditions of various coal beds
Coal mining industry possess mine-free underground gasification using electricity on coal seams of deep seepage having high productivity in hydrogen with low energy consumption and energy gas with radioactive substances removed from the reaction zone
Hydrogen production device comprises gas supply system, a combustion tube, a heating device, a post-treatment device can reduce the later trial-and-error cost and improving the thick oil fire flooding hydrogen production operation efficiency
Method and system for producing hydrogen gas from salt water through electrolysis using the DC power supply
H2 generation during serpentinization varies based on temperature and protolith composition. Predicted aH2(aq) for serpentinization of fayalite is highest at temperatures of 180°C or lower
Subsurface hydrogen trapping capacity can enhance through co-injection with aqueous sodium dodecyl sulfate (SDS) which reduces hydrogen-water interfacial tension and enhances viscoelasticity
Fe(III)-(hydr)oxide reaction on mafic and ultramafic rocks results in the production of hydrogen. The transfer of electrons between Fe(II) and water adsorbed to the spinel surfaces promotes the generation of molecular hydrogen at low temperatures
Introducing the amphiphilic aqueous sodium dodecyl sulfate (SDS) surfactant significantly enhances subsurface hydrogen adsorption through its hydrophobic tail
The hydrogen reduction of pyrite in the presence of alkaline oxide is suitable for desulfurization of high-sulfur bauxite and for iron extraction from pyrite. When agitated, adjusting the hydrogen concentration and spatial velocity of the gas significantly improved the reduction of pyrite in the presence of alkaline oxide, thereby increasing the reduction efficiency
The presence of low silica activity is crucial for the production of hydrogen during serpentinization. Low silica activity environments can exist in olivine-rich rocks like dunite, or during local disequilibrium in other silica-poor rocks in the mantle lithosphere
Well production
In-situ hydrogen production in an oil reservoir, comprises a temperature detection well for detecting the temperature of a middle horizontal well, hydrogen filtering membrane is arranged at the upper horizontal well, heating device is arranged at the middle horizontal well injecting water vapor to produce hydrogen. Filtering membrane improves the underground hydrogen production efficiency and improves the energy utilization rate
Fracturing technology and device comprises light source and aqueous solution of photochemical catalyst get irradiation to enable oil-gas reservoir rock cracking in the underground of well. Light source for photochemical catalyst has improved long-distance hydrogen transport, safety guarantee, lowers production cost for infusing hydrogen
The fracturing ability of a hydraulic fracturing fluid used in an electrical-based fracturing technique can be enhanced by adding electrically conductive materials, such as additives and/or proppants, to the fracturing fluid
Modified version of the OPGEE open-source oil & gas life cycle assessment tool used to model the energy use and emissions from geologic hydrogen systems
Advancing natural hydrogen exploration by analyzing headspace gas of agitated groundwater from dedicated shallow boreholes to better estimate hydrogen gas flux and its variations over time
The production of hydrogen through serpentinization in ultramafic-hosted hydrothermal systems is simulated by combining thermodynamic and dynamic modeling within a thermo-hydraulic single-pass model. The numerical simulations demonstrate that the venting site can consistently produce the observed high concentration of hydrogen throughout the continuous lifetime of the Rainbow site.
