Feb 16, 2023 · There might be enough natural hydrogen to meet burgeoning global demand for thousands of years, according to a U.S. Geological Survey (USGS) model that was presented in October 2022 at a meeting of the Geological Society of America.

Dec 13, 2024 · A recent review of the occurrence of natural hydrogen on Earth estimated the annual global production from geologic environments to be 23 ± 8 Mt year −1 . This estimate is based on a limited number of laboratory experiments and field observations that have been extrapolated to the global scale.

Feb 8, 2024 · Truche et al. found a large natural source of hydrogen gas emitting from deep within the Bulqizë chromite mine. This large hydrogen flux is likely from long-term accumulation within a faulted reservoir.

Feb 8, 2024 · Truche and colleagues believe the hydrogen emissions began when a mine shaft punctured a fault zone that holds pockets of trapped gas. Based on estimates of the fault zone’s size, the researchers say it could hold from 5000 to 50,000 tons of hydrogen.

Sep 7, 2023 · Hydrogen has drawbacks as an energy source: It is less energy rich than natural gas and occupies large amounts of space. But experts think it could replace fossil fuels in long-haul transport and heavy industries such as steelmaking—if it could be sourced in an environmentally friendly way.

Feb 16, 2023 · First up this week: a gold rush for naturally occurring hydrogen. Deputy Editor Eric Hand joins host Sarah Crespi to discuss drilling for hidden pockets of hydrogen, which companies are just now starting to explore as a clean energy option. Next …

Aug 14, 1998 · It has been proposed that hydrogen produced from basalt–ground-water interactions may serve as an energy source that supports the existence of microorganisms in the deep subsurface on Earth and possibly on other planets.

The hydrogen peroxide is photochemically generated from organic constituents present in the water; humic materials are believed to be the primary agent producing the peroxide. Studies with superoxide dismutase suggest that the superoxide anion is the precursor of the peroxide.

Mar 17, 2017 · Unfortunately, although in theory APT can resolve hydrogen without any instrumental modification, naturally occurring hydrogen is present as a major element in most analyses. Hydrogen in these cases is primarily a contaminant from the high vacuum chamber of these systems (29, 30).

During melting and fabrication, as well as during use, there are various ways in which metals come in contact with hydrogen and absorb it. The absorbed hydrogen may react irreversibly with oxides or carbides in some metals to produce a permanently degraded structure.
