Liquid Hydrogen Pipes

The problem

Transporting liquid hydrogen requires more than just containment — it demands precise thermal control, minimal mass, and absolute reliability at cryogenic temperatures.

Conventional cryogenic piping often has:

  • Excess weight and high thermal mass which reduces overall efficiency
  • Welded joints that add leak risks and complexity 
  • Limited flexibility for routing and integration 

Our solution: 

Ultima Forma’s patent-pending twin-walled vacuum pipe is engineered for efficient, lightweight, and flexible liquid hydrogen transfer.

  • Twin-walled vacuum insulation dramatically reduces heat ingress
  • Integrated fittings and expansion joints — no welds, fewer leak points
  • Complex geometry capability — fabricated seamlessly, even around bends
  • Minimal thermal mass — cuts hydrogen boil-off during fueling
  • Sensing - integrated LH2 sensors in development

Proven technical performance in LH2 test:

  • Mass per unit length: 0.6 kg/m 
  • Vacuum: better than 4 × 10⁻⁶ mbar
  • Heat flux: better than 0.18 W/m
  • Demonstrated 2.8× lower heat leak than current market solutions

Why it is better:

  • Lower weight improves overall system efficiency and payload performance
  • Reduced boil-off saves hydrogen and operational cost
  • Simplified integration through flexible, seamless routing
  • Fewer joints mean lower fabrication and maintenance effort
