Heat Below

Synopsis: An introduction to the exploitation of two forms of geothermal energy in the UK (aquifers and the hydrofracturing of hot dry rocks) as sources of hot water for space heating and other low temperature process heat applications. Deals with the Southampton Geothermal Energy Project in which an aquifer has been successfully tapped at a depth of 1800m. from which approximately half a million gallons a day of hot water at 700C are now being recovered using nitrogen gas pumping to increase yields. Rosemanowes Quarry in Cornwall is featured in the second half of the film which deals with the hydrofracturing of hot dry rocks developed by the Camborne School of Mines.*
