  • United Downs Deep Geothermal Power Project, UK. Project Update
    PROCEEDINGS, 44th Workshop on Geothermal Reservoir Engineering Stanford University, Stanford, California, February 11-13, 2019 SGP-TR-214 The United Downs Deep Geothermal Power Project Peter Ledingham, Lucy Cotton and Ryan Law Geothermal Engineering Ltd, Falmouth Business Park, Bickland Water Road, Falmouth, Cornwall TR11 4SZ, UK [email protected] Keywords: United Downs, Cornwall, UK, Deep Geothermal, ABSTRACT The United Downs Deep Geothermal Power project is the first geothermal power project in the United Kingdom. It is located near Redruth in west Cornwall, UK and is part-funded by the European Regional Development Fund and Cornwall Council. The project consists of two deviated wells; a production well to a target depth of 4,500m and an injection well to a depth of 2,500m. Both wells target a sub-vertical, inactive fault structure that is thought will provide enhanced permeability relative to the surrounding granitic rock, sufficient to support circulation of between 20 and 60l/s. Geothermal gradients in Cornwall are relatively good and the bottom hole temperature is expected to be in the region of 190OC, allowing anticipated production to surface at greater than 175OC, which should allow electricity generation of between 1 and 3WMe. After funding agreements were signed in June 2017, a period of preparation and procurement followed, and drilling began in November 2018. This paper places the project in the context of previous geothermal research carried out in Cornwall, summarises the concept and describes the site selection work carried out. It also outlines the microseismic and noise monitoring programmes implemented to protect the local community and describes the public outreach, education and research initiatives associated with the project.

    Proceedings World Geothermal Congress 2015 Melbourne, Australia, 19-25 April 2015 Country Update for the United Kingdom Tony Batchelor1, Robin Curtis1, Peter Ledingham1, Ryan Law2 1GeoScience Limited, Falmouth Business Park, Bickland Water Road, Falmouth, Cornwall, TR11 4SZ, UK 2Geothermal Engineering Limited, 82 Lupus St, London, SW1V 3EL, UK [email protected] Keywords: Country update, United Kingdom, low enthalpy, direct use, mine workings, coaxial heat exchanger, EGS, HDR, GSHP ABSTRACT The exploitation of geothermal resources in the UK continues to be minimal. There are no proven high temperature resources and limited development of low and medium enthalpy resources. However, in the reporting period 2010-2015, there has been a significant resurgence of interest in all aspects of geothermal energy in the UK. New geothermal assessments and reports have been produced, and several deep aquifer projects, minewater projects and EGS/HDR projects are at various preliminary stages. Two EGS/HDR projects in Cornwall have sites and planning approval. In terms of real activity "in the ground" a new deep hole has been drilled in the centre of Newcastle, and ground source heat pump installations have continued, albeit at a lower rate of growth than had been anticipated. A direct use, deep coaxial heat exchanger project is underway. "Geothermal" seminars and conferences have been held, and the UK has increasingly participated in EU and international geothermal initiatives. Compared to previous updates, there has been a significant awakening of geothermal interest in Scotland. Over this period there has been increasing recognition both at European and at UK national levels of the importance of delivering secure low carbon sources of heating.
