Liquefied hydrogen storage tank

Abstract

The present disclosure relates to a liquefied hydrogen storage tank, and more specifically, to a liquefied hydrogen storage tank which facilitates transportation of the storage tank by manufacturing the storage tank storing liquefied hydrogen in a doughnut shape, can improve the robustness of the storage tank and reduce the weight thereof by forming a vacuum layer, improves the temperature maintenance performance of liquefied hydrogen through the shape allowing a second tank unit to surround a first tank unit, and improves thermal insulation through the coating layer.

Dependencies are inferred from the claim text.
