In-situ Injection of Hydrogen Gas in the Opalinus Clay
19 Nov 2014Steel components are generally used in the design of deep geological repositories for high-level radioactive waste. After closure of the underground disposal galleries, anoxic corrosion of steel is expected to produce hydrogen gas. Studies are performed to evaluate what will happen to this hydrogen in an underground repository. Among these studies is the “Hydrogen Transfer” (HT) experiment, which was implemented in 2009 in the Mont Terri Rock Laboratory to study in-situ the diffusion of hydrogen in Opalinus Clay. A second objective of this experiment was to evaluate whether hydrogen could be consumed by chemical reactions with the rock.

Gas Generators and AnalyzersGas generators are used for supplying or monitoring a regular flow of a high purity gas such as nitrogen, hydrogen or zero air for applications such as gas chromatography. Gas analyzers can be used in supply chain processes and laboratory experiments with portable analyzers for monitoring CO<sub>2</sub> and O<sub>2</sub> levels as well as trace gases. Regular flow can be produced with gas control modules and flow meters. Find the best gas generators and analyzers in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity. Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.Syringe PumpHydrogen
