Technical Field: Potential energy storage.

Background Art:

Practically Energy can be stored as many ways as potential behind rivers dames, chemicals battery, and potential batteries.

All over the world, Potential energy stored, it stored to can be use later on to generate electrical power. Previous art is to inject water in large cylinder bottom have big mass to raise-up the big mass to gain potential energy.

Disclosure of invention.

^** This invention based on storing the energy (Ep) as potential energy, by raising-up a big mass (m), designed to behave as a piston and moving freely in a big cylinder have volume (V) with high (h), diameter (d) and area (A), This big mass can raising-up by inject the cylinder bottom high pressure air gas (p) from an pump to pounce this big mass potential energy.

^** From the cylinder bottom we can draw flow gas (Q) to run air gas turbine that drive electrical generator.

^* Free piston Mass. M(kg) effect force=F=m.g kg.m/ s ² (N)

*the effected force a long height distance=L.

Where R=0.287 KJ/Kg °k for ideal gas. 4- Brief description of the d rawing :-

Fig (1) it's about Pressured Air Potential Energy Storage (PAPES) cycle. The compressed air flow to the system through 4 to 9 and to non return valve number 8 under high designed pressure injected inside the cylinder to affect force more the force of (m) against the gravity. This force raise-up part no. 1 to gain potential energy. During cylinder no.2 filling with air gas we can consume the high pressure gas flow through 7 and 9 to run turbine to drive electrical generator.
