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 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 ...

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

With the depletion of fossil fuels and global warming, there is an urgent need to seek green, clean, and efficient energy resources. Against this backdrop, hydrogen is considered a potential candidate ...

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.

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

Hydrogen bubbles sometimes stick on cathodes and oscillate before being released, reducing the efficiency of water splitting.

Green hydrogen Australia is reshaping clean energy by using renewables to cut emissions and fuel industry, transport, and exports.
