  1. Explain the best methods of storing hydrogen. 11720026 Daisuke Ishikawa

  2. “Liquid hydrogen or Compressed hydrogen” Methods of storing hydrogen Introduction “Chemical storage” Metal hydrides, Carbohydrates “Physical storage” Carbon nanotube, Cryo-compressed

  3. Advantages A method to liquefy like gasoline is ideal to store hydrogen most compactly. Liquid hydrogen or Compressed hydrogen It is suitable for the mass transit. Disadvantages Hydrogen has low liquefaction temperature with -253 degrees Celsius. It needs big energy to liquefy.

  4. Liquid hydrogen or Compressed hydrogen

  5. Chemical storage

  6. Advantages The hydrogen filling density is extremely higher than gas. It can prevent the outbreak of the accident by the sudden hydrogen leak. Chemical storage Disadvantages These metals except Mg and V are very heavy. There are the heat with the reaction.

  7. Hydrogen carriers based on nanostructured carbon have been proposed. Physical storage Despite initial claims of greater than 50 wt% hydrogen storage, it has generally come to be accepted that less than 1 wt% is practical. There is a capillary array same way of carbon nanotubes.

  8. State of hydrogen storage system

  9. “Compressedhydrogen is mainstream now.” ‘More efficient’ Conclusion Safety Low cost Light Big capacity Chemical storage Physical storage

  10. Thank you for your attention
