The market of compressed gases in the XXI century needs a technological leap forward. The first air gases generation plant opened back in 1907 and gases are bottled in steel cylinders since then. The only progress has been service pressure, form the initial 100 bar to 150, then 200, to the present 300 bar, but always in steel cylinders. Evolution of technology in these last 100 years should allow us to make much lighter cylinders with the same resistance at a similar cost. These cylinders allow carrying twice as much product in a single truck, so it reduces costs and CO2 emissions.
