Hydrogen Consulting and Analysis

“G2MT Labs provides unparalleled expertise in hydrogen testing, consulting, and analysis”

From high-temperature hydrogen attack (HTHA) to embrittlement, hydrogen plays a critical role in the life, and often the failure, of many metals. And yet, it’s poorly understood by most engineers and rarely accounted for. Fortunately, we’ve spent decades working on hydrogen issues and can help you understand, accommodate, and evaluate hydrogen both experimentally and theoretically to solve your problems. Our team of experts can help with analyzing, replicating, and testing for the many effects of hydrogen to help provide the answers you need.

Experienced Hydrogen Consultants and Scientists

Our CTO, Dr. Lasseigne, is widely recognized as a leading hydrogen expert with very extensive experimental and theoretical knowledge of hydrogen and its effects. She has experience with hydrogen in a broad range of areas including: industrial and nuclear metals, welding, fuel cells and battery materials, pipelines, refineries, and power generation. Her hydrogen research and testing work has covered a great number of materials, as well, including steels, titanium, fuel cells, zirconium, reactive metals, nickel lanthanides, sodium alanates, and numerous other materials. The unique and extensive testing she has performed on hydrogen in numerous different materials is providing new insights into its nature and effects and have been described in dozens of publications.

Case Study: The Effect of Magnets on Hydrogen

Corrosion differs drastically when an applied magnetic field is used (as on the right) during electrochemical charging in a mild sulfuric acid solution. The real (and incredibly powerful) effect of hydrogen is evident in many materials [1, 2]. For example, in the picture above, there are two specimens, one which had no magnetic field (left) and the other with an applied magnetic field (right), showing the effects of magnetism on hydrogen diffusion into steel. The magnetized sample, on the right, suffered severe corrosion and pitting while the other sample is nearly untouched. Effects of magnets and hydrogen levels on corrosion in pipeline steelIn this case, the magnetic field accelerated the corrosion process by increasing the rate of current exchange, resulting in H2 supersaturation that led to both pits and cracks simultaneously forming as shown below. Electrochemical analysis in mild sulfuric acid was performed, including EIS, to evaluate the effects of varying magnetic fields on this pipeline steel alloy.

Our facilities include electrochemical and gaseous hydrogen analysis systems that are capable of a wide range of experimental hydrogen charging tests from low temperatures (down to -40 C/F in our low-temperature environmental chamber) to high-temperatures (up to 1287 C (2350 F) in our hottest furnace). Most importantly, though, we have the practical experience dealing with hydrogen to ensure we achieve what we set out to do, no matter which test you select. We look forward to helping with your hydrogen issues!
