UK's First Deep Bore Geo-thermal Project?
The Eden Project in Cornwall, a cool looking Geo-dome visitor centre, plans to be the UK’s first deep bore geothermal hot rock-powered project.
Cornwall has large granite mass at relatively shallow depths of about 3km. Water from the proposed boreholes would emerge at 150 centigrade and be used primarily to heat the geo-domes. The rest of the heat would be turned into electricity via a heat exchanger system.
In addition to powering the Eden project the company aim to supply up to 5000 homes with electricity. The projected completion date is 2012.
