Influence of hydrogen on metallic components for clean energy (2009–2012)

Hydrogen (H) has caused catastrophic failures of stressed metallic components, particularly steel components. This is hydrogen embrittlement (HE). HE of structural materials is an impediment to hydrogen energy technology. This project addresses the need for much better understanding of HE of medium-strength, affordable steels at two levels. We will study H diffusion and trapping in steels to identify or design steel that are useable in H atmospheres, e.g. in pipelines. Understanding the limits for large turbogenerators permits more effective design, leading to improved efficiency (already high), with environmental benefit; lower production cost, with economic benefit; and improved reliability, availability and productivity.
