Review of the Liquid Hydrogen Storage Tank and Insulation System for the High-Power Locomotive

Hydrogen has been attracting attention as a fuel in the transportation sector to achieve carbon neutrality. storage liquid form is preferred locomotives, ships, drones, and aircraft, because these require high power but have limited space. However, hydrogen must be cryogenic state, wherein thermal insulation core problem. Inner materials, including glass bubbles, multi-layer (MLI), vacuum, vapor-cooled shields, are used for insulation. An analytic study proceeds tanks due safety regulations each country. This reviewed relevant literature thermodynamic modeling. The was divided into static, dynamic, systematic studies. In summary, authors summarized following future research needs: optimal design of structure, suspension, baffle, system, can studied minimize boil-off gas (BOG). A dynamic pressure, mass flow, vaporizer completed. change components arrangement from conventional diesel–electric locomotive necessary.
