Resource Management
Geothermal Engineering Ltd (GEL) will be responsible for running and managing the project but will work closely with Arup and the University of St. Andrews on project delivery. The company has extensive experience of geothermal projects (heat and power) in the UK and abroad. The company has recently installed and tested the DGSW technology in an existing deep well as part of the DECC funded Energy Entrepreneurs Fund and delivered the project on time and on budget. The team for this project will consist of the following staff members:
| Entity | Name | Role |
|---|---|---|
| GEL | Ryan Law | Chief geologist and project director |
| David Bridgland | Chief engineer and financial controller | |
| Peter Ledingham | On site operations and Health and Safety | |
