For hydrogen at 20 kilograms of pressure, if storage in steel cylinders is not used, are there any other materials?

For 20 kilograms of hydrogen, instead of using steel cylinders, are there any other materials available? For example, can a fiberglass-reinforced steel cylinder be used?
I’ve seen storage cylinders for a special gas in the Czech Republic; they’re not made of steel, can withstand high pressure, are very light, and are made of engineering plastic. I didn’t understand the instructions regarding what specific material it is (in Czech).
It’s reinforced with glass fiber, similar to those natural gas storage tanks used in the conversion from oil to gas. Do you mean pressure when you talk about 20 kilograms?
Must the design pressure be using a 150-kilogram cylinder?
May I ask what the reason is why the original poster doesn’t want to use a gas cylinder? The cylinders in taxis that use natural gas these days are probably not made of metal, but it’s unclear what the pressure is
The hydrogen tanks in Japan’s hydrogen fuel vehicles are made of carbon fiber, and they can handle much higher pressures.
In taxis, there are on-board coiled gas cylinders, with a steel cylinder still inside the coiled layer.
No steel is needed; other materials can be used, but it’s important to check whether they are suitable
