We were very happy yesterday to welcome our funders, and partners to the official opening of the plant. Thank you for coming and thank you all for backing us. The official opening marked the start of supplying renewable heat to the Eden Project Biomes, Growing Point nursery and surrounding offices and buildings, with an onsite […]
Eden Geothermal
The heat is on
A landmark moment for renewable energy took place at the Eden Project in Cornwall today, Monday June 19, 2023, as the UK’s first operating deep geothermal heating plant since 1986 was opened and is now generating heat. The process of drilling deep into the granite at the home of the world-renowned Biomes in Cornwall was […]
Two containers and a Christmas Tree
The final surface foot print for geothermal direct heat projects is seriously small: the smallest of any energy source. This picture shows our well head (known as a ‘Christmas Tree’ in drilling slang) and one of the containers that houses the heating system: the controller for the downhole pump. Another container has the filters and […]
Renewables in the garden of Eden
Our heating system for Eden Project, Biomes and new greenhouses is nearly ready to go, and the wildflowers around the heat main are looking good. During installation of the heat main to carry heat from the geothermal site to the Eden Project Energy Centre, hibernacula were created for pollinators, topsoil trenches were reinstated and seeded […]
Operations update
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 […]
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, […]
