Low‐Temperature (100°C–300°C) Magnetite Production in Variably Serpentinized Lherzolites Open
The study of the serpentinization process in ultramafic rocks has been revived in recent years in response to the problems of natural hydrogen generation. Serpentinization results in the formation of magnetite, which is often observed in t…

Experimental simulation of H2 coinjection via a high-pressure reactor with natural gas in a low-salinity deep aquifer used for current underground gas storage Open
If dihydrogen (H 2 ) becomes a major part of the energy mix, massive storage in underground gas storage (UGS), such as in deep aquifers, will be needed. The development of H 2 requires a growing share of H 2 in natural gas (and its current…

Physicochemical and microbiological effects of geological biomethane storage in deep aquifers: introduction of O<sub>2</sub> as a cocontaminant Open
The massive arrival of biomethane in geological energy storage will lead to a co-injection of O 2 used during the gas desulfurization process. O 2 induces changes in the microbial community and interactions with the stored gas and formatio…

Dating folding beyond folding, from layer-parallel shortening to fold tightening, using mesostructures: lessons from the Apennines, Pyrenees, and Rocky Mountains Open
Dating syntectonic sedimentary sequences is often seen as the unique way to constrain the initiation, duration, and rate of folding as well as the sequence of deformation in the shallow crust. Beyond fold growth, however, deformation mesos…
