NASA Explores New Method for Ultra-Cold Fuel Storage

Fast Summary

• NASA is testing an innovative cryogenic fluid management technique at its Marshall Space Flight Center in Huntsville, Alabama.
• The approach, called “tube on tank” cooling, uses two cryocoolers integrated with a multi-layer insulation system to achieve zero boiloff storage of liquid hydrogen.
• Super cold fluids like liquid hydrogen and oxygen are key space exploration propellants but face challenges due to their low boiling points and exposure to heat sources in space.
• Helium chilled to about minus 424°F circulates through tubes attached to the tank’s outer wall, while a second set of tubes at minus 298°F intercepts incoming heat using an aluminum heat shield layer.
• Eliminating propellant boiloff is critical for long-duration missions like crewed journeys to Mars or extended lunar stays, requiring effective storage solutions for months or years.
• Current systems vent boiloff vapors due to pressure risks, leading to fuel loss that is unsustainable for longer missions with larger tanks.
• The Cryogenic Fluid Management Portfolio Project involves cross-agency collaboration under NASA’s Technology Exhibition Missions Program.
