Abstract

Le but de la présente invention est de fournir un système de transport d'hydrogène liquéfié permettant à un conteneur-citerne contenant de l'hydrogène liquéfié d'être placé directement et de manière fixe tout en étant mobile, et qui peut servir de réservoir de stockage d'hydrogène liquéfié et réduire les coûts. La configuration selon l'invention porte sur un conteneur-citerne A dans lequel deux vérins composites côté avant et deux vérins côté arrière à l'avant et à l'arrière d'un corps de conteneur 1 en forme de cadre parallélépipédique rectangulaire sont chacun équipés d'un entraînement hydraulique, le conteneur-citerne A étant pourvu d'un réservoir d'hydrogène qui peut être rempli d'hydrogène liquéfié. L'invention comprend un camion B comportant une plateforme de chargement 6 sur laquelle le conteneur-citerne A est chargé. Le conteneur-citerne A peut être chargé sur la plateforme de chargement 6 et séparé de celle-ci depuis le côté avant, et après avoir été séparé, seul le conteneur-citerne A est placé directement au sol G1. Le conteneur-citerne A est transporté entre une installation de stockage d'hydrogène C et une station d'hydrogène D ou entre l'installation de stockage d'hydrogène C et une centrale électrique E. Immédiatement après l'arrivée à l'emplacement souhaité, le conteneur-citerne A est séparé de la plateforme de chargement 6 par l'action de levage et d'abaissement des vérins avant et arrière et est placé directement au sol G1. Immédiatement après ce placement direct, de l'hydrogène liquéfié peut être chargé ou déchargé en une étape.
