Solving the problem of hydrogen embrittlement and failure prediction is a goal of the energy industries. Research has focused on mechanisms while overlooking the cause aspect and Actual field measurements. Currently, total hydrogen can only be measured destructively, by collecting the gas from a heated sample. Even though this method is too gross to sense hydrogen concentration in critical regions, such as local stress concentrations. Measuring it at a specific site is itself a breakthrough, but with monitoring the output, incipient hydrogen cracking can be detected prior to the failure to take place in order to mitigate the failure. We present a characteristic of hydrogen in metals that makes hydrogen measurable in situ. With this knowledge the precursors of crack initiation, growth and failure can be predicted. With correct hydrogen embrittlement models this information can be translated into actionable knowledge of controllable variables to avoid failure. We present cases of exposure of steel to hydrogen, how it progresses, measurement and where it causes failure.
