Scientists have long debated whether most of Earth's vital liquid was delivered via icy comets or was homemade ...

The volume of the ocean, its average purity, and the chemical makeup of H₂O allow a simple estimate of the amount of hydrogen ...

Hydrogen reserves in Earth’s core large enough to supply at least nine oceans may influence processes on the surface today.

Hydrogen gas has the potential to be a green alternative to traditional non-renewable energy sources. This is, in part, due to its high specific energy versus gasoline and natural gas, but also ...

Earth's core contains nine to 45 times more hydrogen than the planet's oceans do, according to a new study that could settle a debate about when and how hydrogen was delivered to Earth.

Researchers have built a pilot-scale solar reactor that produces usable heat and oxygen, in addition to generating hydrogen with unprecedented efficiency for its size. A parabolic dish on the EPFL ...

Hydrogen is a useful gas. Whether you want to float an airship, fuel a truck, or heat an industrial process, hydrogen can do the job. However, producing it is currently a fraught issue. While it can ...

Wherever hydrogen is present, safety sensors are required to detect leaks and prevent the formation of flammable oxyhydrogen ...
