Geothermal resources of the UK

This paper reports that geothermal energy applications and research are being actively pursued in the United Kingdom despite the relatively normal heat flow regime. The cumulative expenditure on geothermal activity from 1975 to 1989 has been approximately Brit-pounds 46 million of 32% of the Renewable Energy Research Budget to date. The first practical application is a 2 MWt scheme at Southampton as part of a district heating scheme. Commercial operation started in February 1988 and further expansion is planned. The UK's enthusiasm for Hot Dry Rock has dimmed slightly as the entire program is reappraised and the long heralded deep exploration hole has yet to materialize. Future activity looks likely to focus on geothermal opportunities that have multiple uses or applications for the fluids in small scale schemes and Hot Dry Rock research will probably be linked to a pan-European program based in France
