Water-Rock Interaction Problems When Storing And Distributing Hot Water In Unlined Rock Tunnels And Caverns

Book chapter, 1981

The storage and transport of water-borne heat directly in rock caverns and tunnels is today a relatively untested technique which is judged to offer economic and technical advantages when applied on a large scale. The storage of hot water however, causes a change in the chemical composition of the storage water and gives weathering products on the exposed minerals of the cavern wall. These exolution and weathering processes are very complex and it is at present necessary to determine the ion exolution rate for each rock type at a certain specific water quality.
