Frontiers in Energy 2015, Volume 9, Issue 2,   Pages 142-147 doi: 10.1007/s11708-015-0357-7

Abstract: The analysis of the failure mechanics, namely hydrogen permeation of vacuum insulated tubing (VIT), indicated that the failure of VIT could be decreased but could not be avoided. To solve this problem, some measures by using non-vacuum materials were proposed and analyzed in this paper. The results show that to fill the tubing with foam-glass beads or high pressure argon may lead to a good performance.
