Energy can exist in many form, two of which are kinetic and potential energy.
The worker is holding a filled gas cylinder still gives the gas potential energy by lifting it above the ground.
The molecules of the gas also has kinetic energy by virtue of their constant random motion resulting in thermal energy.
In conclusion, the energy of the filled gas is both potential and kinetic.
