Scaling the cryogenic barrier for sustainable aviation propulsion with hydrogen: Vanzetti Engineering tests at DLR, Aviation Week & Space Technology, 9-22 March 2026, p 7

In Europe, the German DLR and Italian Vanzetti Engineering have combined to study the adoption of industrial cryogenic experience to aeronautical requirements.   This involves researching into pumping technology, whereas DLR have deep background in hydrogen combustion systems.  Gas manufacturer  Messer also contributed experience of scaling the cryogenic barrier for sustainable aviation propulsion with hydrogen:
