Natural hydrogen has traditionally been defined as molecular hydrogen generated through geological processes within the Earth's crust. However, natural hydrogen systems also include biological production, where microorganisms generate hydrogen as part of their metabolism in environments such as Arctic cold seeps, marine sediments, permafrost, and the deep subsurface. Understanding the interactions between geological and biological hydrogen production is essential for assessing the role of natural hydrogen in Arctic ecosystems and exploring its potential for future clean energy technologies.
In this thematic network on Natural Hydrogen, we integrate expertise in geology, geochemistry, microbiology, and ecology, to study both geological and biological sources of hydrogen, their interactions, and their relevance for the green energy transition.
The overall goal of the network is to support collaboration in terms of research, funding application, education, and increasing general awareness on the topic. The network also aims to set up dialogue with local communities to support just development of this emerging hydrogen source.
The Thematic Network on Natural Hydrogen aims to promote development of joint research within the topics of the network, development of courses on natural hydrogen, mobility of researchers, teachers, and students between participating institutions, and conferences and other events.
