Eden Geothermal hot rocks project hits target with successful drilling of first well
The pioneering Eden geothermal project has successfully completed its first well to nearly 5 km into the Earths‘s crust. The well has a vertical depth of 4,871 m. Its measured depth – the actual length of the well – is 5,277 m, making it the longest onshore well in the UK.
Once complete, the two well project has the potential to supply renewable heat to the Eden biomes and neighbouring industries equivalent to the heat used by more than 35,000 homes, or renewable electricity to that consumed by around 14,000 homes.

Eden Geothermal Project: Well EG-1 approaches final stage
Having exceeded a well length of 5 km the EG-1 well near St. Austell in Cornwall is rapidly approaching its final stage. Drilling hot granite occurs with permanent losses.
The EG-1 well is operated by Eden Geothermal Ltd which has been set up by three partners: Eden Project, EGS Energy Ltd, and Bestec (UK) Ltd to unlock the geothermal energy deep in the granite beneath Cornwall.

COP26 President Alok Sharma visits Eden Well Site
The President-Designate of COP26, Alok Sharma, visited the Eden Geothermal site on Wednesday (19 May) to mark the start of drilling at the pioneering project. Mr Sharma, who leads preparations for the 26th United Nations Climate Change Conference in Glasgow this November, saw in place the 450-tonne capacity, 55-metre high rig drilling 4.5 kilometres into the Earth’s crust.
His pre-G7 visit marks a major moment for the project, which is being delivered by Eden Geothermal Limited (EGL), a three-way partnership between Eden Project Limited, EGS Energy Limited, a leading geothermal development and consultancy group, and BESTEC (UK) Limited, affiliated with BESTEC GmbH, the specialist geothermal developer and drilling advisor.

The Eden Geothermal Project
BESTEC is participating as technical delivery partner in a project part funded by the European Regional Development Fund. The £17.3m Eden Geothermal Project will drill and test the first 4,500-m-deep well of a geothermal energy demonstration system at the Eden Project in mid-Cornwall, UK, followed by one year of heat production to demonstrate greenhouse gas (GHG) savings. It will build on existing research and knowledge of the deep geothermal resource in Cornwall by providing greater understanding of the geology at depth, enabling resources in the region to become characterised as reserves.
The Eden Geothermal Project is operated by Eden Geothermal Ltd which has been set up by three partners: The Eden Project, EGS Energy Ltd, and BESTEC UK Ltd
