This week we take delivery of 4,000m of vacuum insulated tubing which will create the coaxial circulation system in our first well, enabling geothermal heat to be extracted and delivered to the Eden Project to supply the Biomes and new plant nursery. The tubing will be installed in the centre of the well and will […]

Extraordinary achievement award for pioneer of deep geothermal energy Roy Baria
Pioneer of deep geothermal energy Roy Baria has been awarded this year’s ‘Patricius Medal’ at the European Geothermal Congress in Berlin. The award recognises Roy’s “extraordinary achievements in the field of deep geothermal energy worldwide” during a career spanning more than 40 years and several continents. Roy joined Camborne School of Mines’ ‘Hot Rocks’ project […]
Huge increase forecast in European geothermal heating capacity and investment
Independent energy research and business intelligence company Rystad Energy has forecast a huge increase in the European geothermal heating market in the coming years, “as governments scramble to find an affordable alternative to expensive gas-fired heating”. Total installed capacity is projected to surpass 6.2 gigawatt thermal (GWt) in 2030, a 58% increase from the current […]
Installation of heat main to supply Eden Project with geothermal heat completed
Installation of the 3.8km heat main which will supply Eden Project’s Biomes, new greenhouses and other buildings with renewable heat from our geothermal well has now been successfully completed. The new heat main consists of two 150mm (6”) steel pipes – a flow and a return – each encapsulated in a thick layer of insulation […]
FibreLine Intervention (FLI) used in a new context at Eden Geothermal
We’re delighted to have been working with Well-SENSE recently on the novel application of FLI (Fibre Line Intervention) technology in our geothermal well. An innovative approach in a geothermal setting, the FLI has generated enormous quantities of data that complement our existing Wireline pressure and temperature datasets and that will help us better understand the […]
Site operations update
We’ve now completed our well cleaning operation and much of the equipment used for that process is leaving site today. We will be carrying out an air-lift production test on Monday and Tuesday next week. There’s more information about production testing on our well testing page at Well testing – Eden Geothermal Towards the end […]
Eden Geothermal operations update
We’re planning some well cleaning operations at the geothermal site, and some further well testing, towards the end of August. In preparation, a large (40 tonne) vehicle will be arriving at the geothermal site with an abnormal load escort on August 22nd. The vehicle will follow the route previously used to mobilise our drilling rig, […]
We should be ambitious for UK geothermal heat production
Heat accounts for around 40% of UK energy consumption and is responsible for nearly a third of UK greenhouse gas emissions. So we’ll only achieve our commitment to net zero by 2050, and the UK’s interim target of a 78% cut in greenhouse gas emissions by 2035, if we decarbonise our heat supply. Geothermal heat […]
European Geothermal Energy Council outlines strong sector progress in 2021
The European Geothermal Energy Council (EGEC) has produced its annual Market Report, outlining the development of the European geothermal industry over the previous 12 months. EGEC said that the industry had emerged stronger from the pandemic, and noted some of the following sector highlights: The heating and cooling sector had accounted for more than half […]
Eden Geothermal engineer Chris on last leg of RB&I Yacht Race
Eden Geothermal engineer Chris Briggs has swapped his wellsite PPE for yachting gear to compete in the 2022 Round Britain and Ireland Yacht Race. Chris started his race on the trimaran ‘Morpheus’ – currently in first place (just!) in the multi-hull category and overall race leader – before jumping aboard the Open Class racing yacht […]
A behind-the-scenes tour of the Eden Geothermal drilling rig
If you’ve ever wondered what it was like behind the scenes on the drilling rig used on our geothermal well last year, now’s your chance to find out. Join Eden Geothermal Drilling Engineer Robbie Bilsland as he takes you on a beginners’ tour of MND’s Bentec 450 Eurorig, the 55m-high rig that temporarily took over […]
Enthusiasm and hard work bearing fruit in Bugle School’s wild garden
Last year we awarded an Eden Geothermal Community Fund grant to Bugle School, to help them transform their school field into an eco-friendly learning area. We’re so impressed by how much they’ve achieved since then, thanks to the enthusiasm and dedication of staff and pupils at the school. The grant has paid for the materials […]
Eden Geothermal Community Fund update – Trethurgy village playing field
Last year we supported nine community groups from Treverbyn, St Blaise, Carlyon and Luxulyan parishes with Eden Geothermal Community Fund grants to benefit projects in the local area. One of these groups was the Village Hall Committee from Trethurgy, a village right on our doorstep. They applied for just over £3,700 to provide new facilities […]
Phase 1 of injection testing now completed
We’ve now completed our first phase of injection testing and will be pausing to carry out further wireline logging. We’re planning some further injection and production tests at a later date and will post further information here and on social media channels when details are confirmed. There’s more information about well testing at Well testing […]
Well testing restarting
We are restarting geothermal well testing operations this morning. This follows a review of our injection testing programme after the seismicity that was felt and heard last Wednesday. We know that some people want to better understand what caused the felt seismicity last Wednesday. Microseismicity is linked to well testing during the early stages of […]
Felt seismicity – update
UPDATE AT 12:55 ON 1OTH MARCH 2022 The seismic event which occurred at approximately 9.20pm on 9th March was induced by injection testing at Eden Geothermal. These tests have been ongoing since late January and have involved injecting fresh water into the natural fractures near the bottom of the well. Injection testing induces low level […]
Reports of felt seismicity
We are aware that a seismic event was felt and heard in the vicinity of the Eden Geothermal site shortly after 9.20pm this evening. An investigation and analysis of seismic monitoring data have confirmed that the event was linked to testing operations at Eden Geothermal. No damage has been reported, and the event was within […]
Well testing at Eden Geothermal
We’re currently in a phase of testing our first geothermal well. Well tests provide us with essential information about the temperature and permeability of the rock in our target zone, and how water moves through the hot granite deep underground. The results of our tests will enable us to characterise the geothermal resource, and to […]
