Problems at a chromium mine in Albania traced to nearly pure hydrogen in a fault.

MIT engineers developed a way to make clean ammonia, without fossil-fuel-powered chemical plants, using the Earth as a geochemical reactor, producing ammonia underground.

There's increasing evidence that hydrogen formed deep underground by natural processes could be a major new source of carbon-free power. But for now, it's being pursued mainly by small drilling startups.

In eastern France, and in other places around the world, deposits of natural hydrogen promise bountiful power. But questions remain.

Adam Brandt, an energy science and environmental engineer at Stanford University, has conducted a life-cycle assessment of hydrogen production from natural subsurface accumulations, also known as geological hydrogen extraction, to determine whether the idea is practical. In his paper, published in the journal Joule, he looks at factors involved in extracting geological hydrogen, such as the impact on climate change…

Scientists have shown the importance of hot temperatures in maximizing hydrogen peroxide generation from rocks during the movement of geological faults, and say it may have influenced the early evolution, and feasibly even origin, of life in hot environments on the early Earth prior to the evolution of photosynthesis.

The research, led by Geoffrey Ellis, a petroleum geochemist at the U.S. Geological Survey (USGS), has been published in the journal Science Advances. It suggests that tapping...

It's not yet clear if gold hydrogen—a naturally occurring gas trapped in pockets under the ground—is a low-carbon solution or a climate distraction.

While calcifying organisms like oysters and corals have difficulty forming their shells and skeletons in more acidic seawater, diatoms have been considered less susceptible to the effects of ocean acidification—a chemical change triggered by the uptake of carbon dioxide (CO2). The globally widespread tiny diatoms use silica, a compound of silicon, oxygen and hydrogen, as a building material for their shells. That…

New research suggests that Mars' missing atmosphere may have been absorbed by minerals in the planet's clays, in a process similar to geological reactions on Earth. It may explain Mars' loss of its atmosphere and potential to support life, with methane possibly still present and usable as an energy ...

Industries want to harvest naturally occurring hydrogen as soon as possible, but scientists warn of unforeseen consequences.

Research led by the University of Oxford could address the current supply crisis of helium, a vital societal resource. The study proposes a new model to account for the existence of previously unexplained helium-rich reservoirs. The findings, published today in Nature, could help locate untapped reservoirs of accessible helium.

In Canada, Vancouver-based Inomin Mines Inc. announced its application for hydrogen rights at the Beaver-Lynx critical minerals project in British Columbia. This move aims to explore the site's potential for naturally occurring hydrogen, also known as "white hydrogen," which could be a game changer in clean energy production. The project, positioned between two major copper […]

Geologists think there may be vast natural stores of hidden hydrogen gas within Earth, but no one is sure how much there is or how much could be recovered for energy

The amount of helium in underground geological formations could satisfy thousands of years of global demand, researchers said.

The quest to develop hydrogen as a clean energy source that could curb our dependence on fossil fuels may lead to an unexpected place — coal. A team of Penn State scientists found that coal may represent a potential way to store hydrogen gas, much like batteries store energy for future use, addressing a major hurdle in developing a clean energy supply chain.

A study exploring the potential of a decommissioned gas field in Scotland as a major hydrogen store has highlighted concerns over potential leaks and recommended that it shouldn't be used.

Just a year ago, few people took seriously the idea that we could extract hydrogen from the ground as a clean energy source - but now the US Department of Energy is injecting $20 million into the concept
