Hydrogen is an important energy source for variety of microorganisms on this planet. In oxygen-free, subsurface environments with limited electron donors, hydrogen plays a central role in energy metabolisms of anaerobic microorganisms. Sulfate-reducing prokaryotes,...

Welding for Material Tests
As part of work package WP4 “Material and Corrosion”, it is planned to test several metallic materials under hydrogen environment. It is admitted that Heat Affected Zone (HAZ) in a welding can be more sensitive to hydrogen embrittlement. As a matter of fact, thermic...
New article presenting Hystories
European Network for Research in Geo-Energy ENeRG, the European Network for Research in Geo-Energy, in its latest newsletter (issue no43 / July 2021), dedicate a very interesting article to the Hystories project. You can read it here. The European geo-energy...
Full steel characterization
In the course of work package WP4 of the Hystories project, a material characterization of selected steels was carried out by the Chair of General and Analytical Chemistry, at the Montanuniversitaet Leoben. For the further experiments, it is essentially to obtain a...
Selection of aquifers or depleted fields for pure hydrogen storage: a new (under)ground
Experience in pure hydrogen storage in porous media or aquifer is yet to be built There is industrial experience for pure hydrogen storage stored underground in salt caverns: storage has been undertaken since 1972 in Europe (at Teeside, UK), only a decade after...
Short story of Hystories
Hystories is a European research project working on pure hydrogen storage in depleted fields or aquifers. Renewable hydrogen combined with large scale underground storage enables transportation of energy through time, balancing out the impacts of variable...
