A hydrogen storage medium, comprising:
- a cavity;
- and
- a wall surrounding the cavity, the wall comprising a combination material comprising a barrier material and a reinforcing material, the wall having a thickness of not more than 50 mm, and wherein a decadic logarithm of a hydrogen permeability p of the wall at a temperature of 473 K is less than −20.000.
A combination material, comprising:
- a barrier material;
- and
- a reinforcing material, wherein a difference in an average linear coefficient of thermal expansion of the barrier material and of the reinforcing material in a range from 20° C. to 300° C. is not more than 10.0 ppm/K.
