As interest in hydrogen as a green energy source has risen, scrutiny has been placed on hydrogen production's energy demands. A recent paper in Nature Reviews Earth & Environment discusses natural hydrogen generation and its accessibility. While the potential for large accumulations exists, very high concentration deposits are rare. The research suggests that geological processes could aid in bringing hydrogen closer to the surface for commercial use, indicating a path forward for further exploration and utilization of hydrogen resources.
It takes more energy to produce, store and transport hydrogen than it provides when converted into useful energy.
Large accumulations of hydrogen are feasible, but very high concentrations will be exceptional.
Certain types of geological activity help to bring the hydrogen to the near surface where it might accumulate and form a commercial resource.
The paper's findings should make it easier to hunt for reservoirs.
