Pre-dismantling THM modelling of the FEBEX in situ experiment.

Lyesse Laloui, Alessio Ferrari, Yafei Qiao

FEBEX (Full-scale Engineered Barrier Experiment in Crystalline Host Rock) is a research and demonstration project that was initiated by ENRESA (Spain). The aim of the project is to study the behaviour of near-field components in a repository for high-level ...

Rates of microbial hydrogen oxidation and sulfate reduction in Opalinus Clay rock

Rizlan Bernier-Latmani, Alexandre Bagnoud

Hydrogen gas (H2) may be produced by the anoxic corrosion of steel components in underground structures, such as geological repositories for radioactive waste. In such environments, hydrogen was shown to serve as an electron donor for autotrophic bacteria. ...

Reconstructing a hydrogen-driven microbial metabolic network in Opalinus Clay rock

Rizlan Bernier-Latmani, Alexandre Bagnoud

The Opalinus Clay formation will host geological nuclear waste repositories in Switzerland. It is expected that gas pressure will build-up due to hydrogen production from steel corrosion, jeopardizing the integrity of the engineered barriers. In an in situ ...

Device and System Having Water Microelectrolyzer Cells and Method of Using the Same

Demetri Psaltis, Christophe Moser, Miguel Antonio Modestino, Seyyed Mohammad Hosseini Hashemi

A device having a water vapor microelectrolyzer cell including microstructured parallel electrodes where the water splitting reactions can take place, the microstructured electrodes being covered by a thin layer of solid-state ion conducting material to al ...

Direct carbon dioxide hydrogenation to formic acid in acidic media

Paul Joseph Dyson, Gabor Laurenczy, Séverine Joëlle Moret

The present invention relates to a method of producing formic acid in a catalysed chemical reaction from hydrogen gas and carbon dioxide gas, said reaction being conducted in an acidic medium comprising a polar solvent over a wide range of temperatures at ...

Testing of the hydro-mechanical behaviour of shales

Lyesse Laloui, Alessio Ferrari, Valentina Favero

Shales are among the most commonly considered geomaterials in current energy-related geomechanical investigations, as they are involved in engineering applications such as the unconventional extraction of natural gas, CO2 sequestration and nuclear waste ge ...

Numerical analysis of canister movements in an engineered barrier system

Lyesse Laloui, Fabrice Dupray

The mid-term safety of deep geological nuclear waste repositories is based in part on the presence of a buffer, the main role of which is to isolate the environment from radionuclides. A design evaluation of such a repository is necessary to assess the pot ...
