The AirQon project aims to substitute diesel generators with an energy supply system based on Electric Vehicle (EV) batteries to provide off-grid energy for outdoor festivals and events. The solution is based on introducing an innovative technology to control bi-directional energy flow to and from EV batteries. The final ambition is to ensure that events will be utilising AirQon technology for their off-grid energy demand preventing diesel from being burnt in generators. The project will induce higher awareness of clean energy sources and more conscious behaviour, next to that the project is exploring how the technology and its business model can be applied in other contexts.
