5,000 m³ Cryogenic Liquid Hydrogen Dewar Tank Model

Underwrite 5,000 m³ double-walled spherical liquid hydrogen storage tanks with vacuum-expanded perlite insulation (storing 350 tonnes of liquid H2 at 20 Kelvin with boil-off rates <0.05% per day for aerospace launch hubs and hydrogen fuel terminals). Model hydrogen terminal storage tolling fees ($0.45/kg LH2 stored), and 25-yr IRR.
