Lesser-known, but there are solid-state hydrogen storage options that compare favorably to liquid storage (energetically, volumetrically, and inherently temperature & time stable). Best example is storing hydrogen in an aluminum matrix -- Aluminum Hydride, aka Alane. Companies like FuelX are commercializing. https://en.wikipedia.org/wiki/Aluminium_hydride https://en.wikipedia.org/wiki/Aluminium_hydride https://fuelx.tech/ https://fuelx.tech/
