Mountains Could Host Hidden Hydrogen Reserves, Study Finds

Plate tectonics–driven simulations of the Alps, Pyrenees and Baetic mountains suggest deep mantle rocks rose and interacted with water to release hydrogen, which then accumulated in porous rock layers—making the Alps and Pyrenees plausible natural hydrogen reservoirs. The Baetic range, by contrast, uplifted and eroded too rapidly for large hydrogen volumes to form or be retained. If validated, this approach could guide searches for other natural hydrogen sources to support a hydrogen-powered economy.

"Game-Changing Graphene Breakthrough: Cheap and Sustainable Hydrogen Generation"

Scientists have discovered that graphene, a single layer of carbon atoms arranged in a 2D lattice, is naturally permeable to protons and allows for their accelerated movement around nanoscale wrinkles. This breakthrough challenges previous theories and has significant implications for the hydrogen economy, as it offers sustainable alternatives to costly catalysts and membranes. By replacing these with graphene, the production of green hydrogen can be advanced, reducing carbon emissions and aiding the transition to a Net Zero carbon environment. The researchers used scanning electrochemical cell microscopy to visualize proton currents through graphene membranes and found no evidence of holes in the graphene structure, confirming its intrinsic permeability. This discovery opens up possibilities for the development of low-cost catalysts for hydrogen-related technologies.

Unraveling the Proton Permeability Puzzle: Graphene's Role in Sustainable Hydrogen Generation

Researchers have discovered that graphene's permeability to protons is higher than previously thought, with protons being accelerated around nanoscale wrinkles and ripples in the crystal. This finding could revolutionize the hydrogen economy by replacing expensive catalysts and membranes with sustainable 2D crystals, leading to more efficient and environmentally friendly green hydrogen production.
