Summary

[edit]
Description
Deutsch: LH3-Tank für Wasserstofffahrzeuge von BMW - sog. "Kyrospeicher" (kyrogen).
Deutsch: Flüssiger Wasserstoff (LH2 = engl. liquid hydrogen) lässt sich stationären und mobilen Tanks speichern. Durch thermische Isolierungen kann eine Abdampfrate von unter 0,05% erreichen werden. Solche Tanks werden auch Kryotanks oder Kryospeicher genannt (griech. kryos = kalt). Die volumenspezifische Speicherdichte liegt bei 2,13 kWh/l (etwa 4,5 kWh/kg), jedoch muss der Wasserstoff dafür zunächst verflüssigt werden. Die Verflüssigung bedarf einer Energie von 36 kJ/g, dazu wird das gasförmige Wasserstoff zur Verflüssigung auf eine Temperatur von -253 °C heruntergekühlt. Dazu wird etwa einem Drittel der gespeicherten Energie notwendig.
