The Prototype

The Air4NRG prototype will be the tangible illustration of the clean and efficient Air4NRG energy storage process. It will also be a demonstration of the technology on an industrial scale and at TRL5.

The prototype will be made up of two main parts:

  1. The reversible energy compressor and expander, which will be able to transform electricity into compressed air, or compressed air into electricity.
  2. The energy storage, able to store the compressed air in container-sized gas tanks.

Air4NRG technology will use an efficient energy conversion process – isothermal air compression and expansion. It is made possible by the partners’ innovative R&D works in the liquid piston gas compression, already demonstrated in the laboratory.

The Air4NRG prototype is the opportunity to show this innovation on a much larger scale and in a relevant end user environment, operating in real use cases scenarios. It will also be the first step in the work on the scalability and replicability of the technology.
