We make a Compressed Air Energy Storage System

that helps renewable sources store what they've produced!   Unlike batteries, we do not wear down  -  we're with you for life!  Unlike grid- enabled storage, we do not have carbon emissions!

Leaper Qube - Compressed Air Energy Storage

What is Power Storage?

A method by which Electrical Energy is kept for future use

Why do we need it?
To balance demand and/or supply backup power

The Solution!

The LiGE Qube/Air Battery/Eco-mc² is a Compressed Air Energy Storage System.  The operation is based upon the use of renewable energy such as Solar P.V and/or Wind turbine but work well with Grid linked mains.


  • Heat to storage for use during power generation and cooling for the system.
  • Water extraction and provision to utilisation as a water generator.
  • Power storage into compressed air tanks above ground.
  • Air cleaning as a by-product of the air utilisation of atmospheric air.
  • State of the art permanent magnet 3-stage free piston compressor/
  • Direct contact heat exchanger / compressor body / compress air system.
  • Water removal at the first and second compressor.
  • Isentropic heat reintroduction at expander.
  • Maintenance of adiabatic in the range 25 to 40deg C.
  • Stainless steel compressor cylinders.
  • Autonomous system operation.


The power derived from: -


  • Solar P.V. as a DC input.
  • Three phase AC
  • Backup generator


Above input power/s is applied to the compressor via electric motor, the energy is stored as compressed air.


  • As the compressing air passes through the heat exchanger the heat is removed and stored in the heat tank.
  • During compression the air is dried, and the water stored.
  • The compressed air is stored in specialised tanks for use as the driving force in the generation mode.
  • The system is designed to remain Isothermal at 25°C to 40°C.
  • Round trip efficiencies approximately ~74%
  • The entire system is controlled via Valves and an automation controller.


During the power return phase when the stored energy is required the system releases the air via the heat exchanger which, connected to the heat storage, warms the expanding air into the compressor --now working as a motor (but not reversing the direction of rotation).


This in turn drives the Generator three phase motor, a flywheel is attached to the generator to act as a compensator for fluctuations and produces a stable load regulated AC source.
