Liquid Hydrogen


Water

• Liquid or Solid (Ice)• Least pressure on containment

vessel

• Higher Density for Hydrogen• Life Support Systems

Tank Materials


Thermal Management


Location

• Environmental Considerations• OPTIONS:

– Surface• Day temp (107 to 123 deg C)

• Night temp (-153 to –233 deg C)– Permanently shadowed craters allow for less energy

expenditure for cooling

– Sub Surface• Avg. Temp at 1m depth (-35 deg C)

Interfaces (not yet researched)

• Assumed to be based on terrestrial designs.

• Must be adaptable to different transportation systems.

• Ideally standardized.• Must be resilient to leaks and contain a

health monitoring system (leak detection)


Major Problems

• Hydrogen Leaks + Flammability

• Long-term Storage (Oxidized parts)

• Lunar Dust• Rapid Expansion (Asphyxiation)• High Pressure Gases (ruptures/explosions)

– Boil-off (Rocket Fuel Venting)


Health Monitoring and Communication

• Sensors (which ones are vital?)• We need to address the communication

infrastructure! (on some level)• Back-up power supplies
