Résumé

Hydrogen is a versatile energy carrier that offers carbon-neutral solutions for numerous industrial sectors. Liquefaction under cryogenic temperatures increases energy density, but the storage tanks require superinsulation systems to keep hydrogen in the liquid phase. Conventional double-walled spherical tanks have extended production times, low failure tolerances, inefficient shapes, and limited potential for upscale. Therefore, this study investigates the technical feasibility of a novel insulation concept based on the combination of vacuum insulation panels (VIPs) and polymeric foam. A rigid frame sustains the insulation modules and facilitates the inspection and maintenance activities. Considering the complex interaction of materials with different thermomechanical properties, the thermal contractions are accurately evaluated to guarantee structural integrity. In addition, a detailed thermal performance assessment is conducted to guarantee low heat flux and boil-off rate comparable to state-of-the-art technologies. The results prove the technical feasibility of a VIP-based insulation system for large-scale liquid hydrogen tanks.
