Replace the heavy metal cansistors for fuel gas, or for pneumatic air power, with lightweight enforced bottles.

Develop low cost tanks for scuba diving as well as for hellium, for pneumatic cars, for butane home storage or for hydrogen cars.

Since there are plastic chords which can hold tension exceeding tons, it is probably possible to make some kind of low weight high tension resistant fabric with a thin metal layer inside so that the gas cannot escape.

Perhaps even some kind of "wiring" would help in compressing the gas, by "tightening" the container! So you would also get space saving, when empty.

I used to build pressure vessels. Putting something under a lot of hoop stress is all fine, until that person walks into a corner and punctures the weave. Explosive

They do make kevlar and carbon fiber pressure vessels, although I believe high strength metal alloys are still better due to their elastic modulus
