  3. Metal Hydride Storage:
    • Description: Hydrogen is absorbed into a solid metal matrix to form metal hydrides.
    • Advantages: High volumetric and gravimetric storage density, potentially safer than gaseous or liquid storage.
    • Challenges: Limited reversibility (slow hydrogen release and uptake), can be heavy, and may have temperature constraints.
  4. Chemical Hydrogen Storage:
    • Description: Hydrogen is stored in chemical compounds, and it is released through a chemical reaction.
    • Advantages: Potential for high storage density, reversibility, and ease of transport.
    • Challenges: Some chemical processes may require high temperatures, and the regeneration of the chemical compound may involve energy-intensive steps.
  5. Carbon-Based Materials (Hydrogen Sorption):
    • Description: Hydrogen is adsorbed onto the surface of high-surface-area materials, such as activated carbon or carbon nanotubes.
    • Advantages: Relatively lightweight, potentially reversible, and moderate operating conditions.
    • Challenges: Limited volumetric and gravimetric density compared to other methods, adsorption and desorption kinetics can be slow.
  6. Liquefied Organic Hydrogen Carriers (LOHC):
    • Description: Hydrogen is chemically bonded to a liquid organic compound, forming a carrier fluid.
    • Advantages: Liquid at ambient conditions, potentially easier to handle and transport.
    • Challenges: Energy-intensive for both hydrogenation and dehydrogenation, issues with system complexity and cost.
