Buddy Damm, Chief Scientific Officer, Swagelok Chart of hydrogen production, from production to transportation to utilization.Independence from fossil fuels. An energy crisis derived from a geopolitical conflict. The growing urgency of addressing climate change. These are just some of the reasons driving the search for viable alternative fuels. Hydrogen is a promising solution. Managing hydrogen safely and reliably, from generation to end use, is the key to achieving its full potential as a zero-emission fuel source in a wide variety of applications. However, containing and transferring hydrogen presents some unique challenges. Hydrogen is the first element of the periodic table, made up of a single positively charged proton and a single negatively charged electron. It is the lightest atom and one of the smallest. In the developing hydrogen economy, hydrogen will need to be handled in liquid and gaseous states.
Hydrogen liquefies at and is about 140 times denser in the liquid state than in the gaseous state. Transporting and storing H2 in liquid form is more efficient, but at its point of use, H2 is a gas. As a result, there are two phenomena that can affect the metals used in hydrogen systems. Low temperature embrittlement: As the temperature decreases, metals lose certain ductility. Hydrogen embrittlement: Atomic hydrogen can diffuse into the metal and weaken it. In this case, embrittlement refers to a reduction in the ductility and fracture BYB Directory and fatigue resistance of a metal in its service environment compared to its fracture and fatigue resistance in air and at room temperature. These issues can lead to system failures, resulting in security risks, increased downtime, and financial losses. As the hydrogen industry continues to expand, it is critical to resolve these system construction issues if the fuel is to be adopted as a long-term sustainable solution.
SUMMARY OF HYDROGEN DATA So how can hydrogen professionals build hydrogen driving systems that last? It is essential to remember that materials are important for hydrogen containment. Fluid systems made from specifically formulated high-quality stainless steel can better withstand the challenges inherent in hydrogen containment. The following FAQs explain how and what those responsible for selecting materials for hydrogen containment components should consider. Graph showing the effect of temperature on the weakening of different types of stainless steel Q: What is low temperature embrittlement? A Low temperature embrittlement refers to a reduction in ductility, strength, or resistance to fatigue and fracture as temperature decreases.
