Hydrogen can bond strongly with iron in extreme conditions

Hydrogen can bond strongly with iron in extreme conditions
There may be up to 70 times more hydrogen in Earth s core than in the oceans.

Hydrogen is one of the possible alloying elements in the Earth’s core, but its siderophile (iron-loving) nature is debated.
In a new study by the University of Tokyo, scientists experimentally examined hydrogen partitioning between molten iron and silicate melt at 30–60 gigapascals and 3100–4600 kelvin. The experiment involved a diamond anvil and chemicals in simulating the core of the young Earth. ....

High-temperature and high-pressure experiments involving a diamond anvil and chemicals to simulate the core of the young Earth demonstrate for the first time that hydrogen can bond strongly with iron in extreme conditions. This explains the presence of significant amounts of hydrogen in the Earth s core that arrived as water from bombardments billions of years ago.
Given the extreme depths, temperatures and pressures involved, we are not physically able to probe very far into the earth directly. So, in order to peer deep inside the Earth, researchers use techniques involving seismic data to ascertain things like composition and density of subterranean material. Something that has stood out for as long as these kinds of measurements h ....
