This project investigates an alternative to substation batteries.
The project is to evaluate the dependability, performance and application of the Pnu Power DC Supply Compressed Air Energy Storage System. This system offers a promising alternative to a traditional charger and battery system used for substation light current supplies. It could provide an alternative, reliable, low maintenance and environmentally friendly solution, which can provide a scaled and flexible DC output capability.

The project will consist of laboratory tests, type tests and a pilot installation and evaluation.
