Stratospheric Platforms: Novel insulation for liquid hydrogen tanks

Stratospheric Platforms Ltd (SPL) is developing unique insulation technology for liquid hydrogen (LH2) tanks. This technology provides a low-risk, high-performance pathway to liquid hydrogen powered flight for both passenger and High-Altitude Platform Station (HAPS) aircraft. A key advantage of the technology is it does not rely on vacuum, reducing hazards and complexity whilst achieving improved weight and overall vehicle thermal management. SPL has previously validated this concept with successful tests on small-scale prototypes. In this demonstration, SPL will create a new higher fidelity prototype tank and insulation system and test it using liquid hydrogen to further validate thermal performance models.
