Everybody loves a treasure hunt, and it turns out there is a massive source of renewable energy buried right beneath Vienna. A project called „Deeep“ is on the verge of tapping into it and making the Austrian capital one of the world's first major cities to have geothermal energy become a big part of its future energy mix. To find out more about this ambitious treasure hunt, the progress made so far and the promise for tomorrow our host and journalist Steve Chaid is joined by two guests in this episode. Peter Keglovic is the project manager for geothermal energy at „Wien Energie”. Bernhard Novotny is head of OMV's Geothermal Projects in Low Carbon Business.
