The use of a conduction-cooled, refrigerated and insulated storage vessel for liquid hydrogen is proposed as an alternative that can allow a reduction in the thickness of the vessel's insulation and can extend storage times by directing the in-leak heat towards one or few refrigerated cold sectors in the insulation of the vessel. This heat is conducted through one or few copper layers incorporated in the insulation. Although evaporative loss of hydrogen is prevented with the proposed design, refrigeration work must be provided to remove the in-leak heat. Allowing evaporation to produce hydrogen gas that can be used for power generation in the vehicle's fuel cell helps reduce the cooling load of the refrigerator.
