This is likely an absolutely stupid idea, but in a structure where ventilation isn't an option, what would be the impact of having a "pilot light" in areas where hydrogen accumulates? Essentially burn it off before it accumulates to the point of presenting a significant hazard. Additionally, (perhaps primarily) if the molecules seep through a sealed tank, wouldn't they escape an overhang/roof with far more ease?
