Educate and update the broader public about the principles, opportunities and innovations in the natural hydrogen sector as it begins to emerge
A weekly newsletter with all the latest updates in the sector plus some deep dives on specific topics and themes
Natural hydrogen is the term given to hydrogen that is found in its gaseous form under the Earth's surface. It is also known as geologic hydrogen - or for those of you that like the colour labelling - white/gold hydrogen
It was commonly believed by the majority of academic and industrial circles that hydrogen gas was unlikely to be found underground in any significant quantities. The reactivity of hydrogen means that it's mostly found as water (H20) or hydrocarbons (e.g. methane - CH4). However, under certain geological conditions, it is possible that large concentrations could exist, we simply haven't been looking in the right places or with the right equipment to find it. Were significant volumes to exist, then it is feasible to think that it could be extracted for use in the emerging low carbon hydrogen sector
It is understood that natural hydrogen can form in a number of different ways. But, no matter how it is formed, one of the primary requirements for the presence of large reserves of hydrogen gas is cap rock or a seal, an impermeable layer of rock, silt or salt that sits above the formation and prevents the light hydrogen molecules from rising to the surface and leaking into the atmosphere. Here are the main 3 production pathways:
1) Serpentization - chemical reactions occurring in iron-rich rocks
2) Radiolysis - radioactive decay causing water molecules to be split
3) Organic processes - decaying organic matter
