Working visit Vienna tunnel solutions
At the invitation of ASFiNAG, a European delegation of tunnel organizations visited a tunnel project in Vienna on 6 and 7 December 2022. This working visit was initiated by the COB. This project, a road route and the tunnels within, is made completely self-sufficient by means of solar panels. The surplus of energy that’s produced is transported via its own medium voltage cable to high-quality batteries from the German DHYBRID, where it’s stored. The batteries are placed inside or outside the tunnels, depending on the available space. This storage allows a power failure of approximately ten hours to be bridged and no other emergency power supplies are required.
