Environmental risks and opportunities of orphaned oil and gas wells in the United States
Environmental Research Letters, 2023 Hundreds of thousands of documented and undocumented orphaned oil and gas wells exist in the United States (U.S.). These wells have the potential to contaminate water supplies, degrade ecosystems, and emit methane and other air pollutants. Thus, orphaned

What Pulsating H2 Emissions Suggest about the H2 Resource in the Sao Francisco Basin of Brazil
Geosciences, 2020 Proterozoic sedimentary basins very often emit natural hydrogen gas that may be a valuable part of a non-carbon energy infrastructure. Vents in the Sao Francisco Basin in Brazil release hydrogen to the atmosphere mainly during the daylight half of the ...

Transport Cost for Carbon Removal Projects With Biomass and CO2 Storage
Frontiers in Energy Research, 2021 Strategies to remove carbon from the atmosphere are needed to meet global climate goals. Promising strategies include the conversion of waste biomass to hydrogen, methane, liquid fuels, or electricity coupled with CO2 capture and storage (CCS).

Geofizicheskiy Zhurnal, 2020 Formation of geological (abiogenous) hydrogen in the interior is connected with two groups of hypotheses: production of secondary hydrogen in the Earth’s crust and upper mantle as a result of its emission from water and some minerals as well as discharge of primary hydrogen from the core and lower mantle accumulated in the depths during accretion of ...

Geochemistry, Geophysics, Geosystems, 2020 Water controls magmatic crystallization and drives volcanic eruptions, but little is known about its primary source in silicic systems. The hydrogen isotope composition of volcanic products provides a metric that can track and identify magmatic source ...

Bubble Coarsening Kinetics in Porous Media
Geophysical Research Letters, 2023 Bubbles in subsurface porous media spontaneously coarsen to reduce free energy. Bubble coarsening dramatically changes surface area and pore occupancy, which affect the hydraulic conductivity, mass and heat transfer coefficients, and chemical reactions ...

Geophysical controls of chemical disequilibria in Europa
Geophysical Research Letters, 2016 The ocean in Jupiter's moon Europa may have redox balance similar to Earth's. On Earth, low‐temperature hydration of crustal olivine produces substantial hydrogen, comparable to any potential flux from volcanic activity.

Hyperspectral Imaging Techniques in Search of Geologic Hydrogen: A Review
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingNew energy sources are crucial for powering next-generation transportation and supplying reliable energy in remote regions. Hydrogen is an attractive energy carrier because its utilization produces only water as a byproduct.

The Influence of Growth Rate on 2H/1H Fractionation in Continuous Cultures of the Coccolithophorid Emiliania huxleyi and the Diatom Thalassiosira pseudonana. [PDF]
PLoS ONE, 2015 The hydrogen isotope (2H/1H) ratio of lipids from phytoplankton is a powerful new tool for reconstructing hydroclimate variations in the geologic past from marine and lacustrine sediments. Water 2H/1H changes are reflected in lipid 2H/1H changes with R2 >
