Hydrogen Storage in Metal Hydride Beds

• Some metallic Alloys makes compounds with
  Hydrogen
• MH2 ? MH2 Heat
• It is possible to store large amount of Hydrogen
  in Metal Hydride bed at low pressure (5-20 bar)
• 8.2 gr Hydrogen can be stored in 100 cm3 LaNi5
• Only 3.1 gr Hydrogen can be stored in 100 cm3
  volume at 350 bar pressure
• ? Metal Hydride beds has great potential for
  Hydrogen Storage applications

Two Phase Flow in Electrolysers

• Hydrogen, Oxygen and electrolyte makes two phase
  flow
• Adapt and Develop Mathematical Model for
  Electrochemical System based on Two Phase Flow
• Investigate effect of flow on the hydrogen
  release rate
• Investigate flow regimes for better gas evolution
• Devise an Experimental Setup
