    About The talk:

    Several materials and corrosion related challenges needs to be considered for safe operation of oil and gas industry assets. Hydrogen embrittlement is one of the several mechanisms that presents a significant risk. Nickel based alloys are used as structural material in subsea high pressure high temperature oil and gas production systems due to their excellent corrosion resistance in the harsh environments. However, there is a risk of hydrogen embrittlement from potentials that are encountered as a result of being in contact with other metallic systems with imposed cathodic protection. The impact on fracture and fatigue properties for this system are presented along with the use of electrochemical and modeling tools to understand the fundamentals of hydrogen embrittlement pertinent to the Ni system. Recently, there has been a significant push to reducing the carbon footprint of the oil and gas industry and hydrogen is being proposed as a cleaner alternative to natural gas. Currently the gas transmission and distribution networks are designed for natural gas. Hydrogen is proposed to be blended with natural gas to use the existing infrastructure; however, this poses risks of hydrogen embrittlement.
