Maximum storage pressures in steel vessels for hydrogen containment can potentially be doubled by incorporating hoop wraps using high strength steel wires coupled with autofrettage. An integrity analysis for Type II pressure vessels consisting of liners made from SA372 grade J steel and hoop wrapped with high strength steel wire is presented. Fatigue crack growth rates were measured in liner material in 10 MPa gaseous hydrogen at load ratios, R, in the range -1 ≤ R ≤ 0.2 using single edge crack tension specimens. Growth rates under negative load ratios were comparable to the rates at low positive load ratios. These results are used to compare design lives and durability of cylinders in hydrogen and in air environments.
