Chex Energy Storage

Chex Energy Storage (Chex ES) works by storing energy as a compressed gas in a high-pressure tank. This gas is then released into a closed system of pipelines, which makes it expand.

This expanded gas goes into a water-filled tank, and as the gas enters the tank, it pushes the water through a pipeline and through a water turbine. As the water passes through turbine, it enters a second empty tank until it is filled. Afterwards, more gas is released into the system, which now enters this second tank and again pushes water through the turbine and into the first tank.

This is a cyclical process that uses a constant amount of liquid. The length of each cycle, and the amount of energy it can produce, depends on the size of each tank and the flow of water that passes through the turbine. This allows for various types of applications.

In this manner, Chex ES can store any kind of energy, just like a battery, but in a truly sustainable manner because it does not require environmentally harmful chemicals to operate.

Chex ES Applications

Chex ES S

An 8 [KW] unit for energy storage designed for residential and semi-industrial users. The Chex S-Unit can store energy generated by a small solar panel installation or a solar home-roof-array.


Chex ES M

A 100 to 1000 [kW] unit. The M-Unit provides energy storage solutions for large photovoltaic installations and windmill farms. Easily scalable, it can also store excess energy from the grid.


Chex ES μ

The μ-unit provides power to small devices such as cameras and public lightning systems.
