Students from the Student Energy Storage Circle at the Warsaw University of Technology (PW) are working on a project to develop an energy storage in compressed air.

The project of the Student Energy Storage Circle PW has been completed: Compressed Energy Energy Storage (CAES) project. The team had been working on it for over a dozen months.

The students have completed most of the construction works including “preparing the valve part for flow regulation, preparing the pipes, connecting them with air reservoirs, sealing all connections and constructing a heat exchanger”. The model is developed in adiabatic technology, which means that the heat from the compression process is used to heat the air before the turbine. It is an innovative technology thanks to which the “need to bring energy from outside the system” is avoided.

The final stage of works will be the construction of a Tesla turbine that will drive a small generator of electricity.
