Groundworks complete and drilling to start soon at Eden Geothermal

After a year of intense activity, deep drilling is soon to commence at the pioneering Eden Geothermal Project near St Austell in Cornwall.

Next week, the first lorries carrying a 450-tonne, 55 metre-high drilling rig will arrive on the outer edge of the Eden Project site, the home of the world-famous Rainforest and Mediterranean Biomes.

Once fully assembled into position on a newly-laid concrete platform, the rig will be ready to drill 4.5 kilometres (nearly three miles) down into the Earth’s granite crust.

The first phase of drilling is expected to take five months and when complete will allow water to be injected down the borehole to be superheated by the hot rocks beneath.

The hot water will then be pumped back to the top via a pipe suspended in the same borehole, generating heat initially to warm Eden’s Rainforest and Mediterranean Biomes, offices, kitchens and greenhouses. The same water will then be re-circulated to be superheated and used again.

Following the successful completion of this first phase, the next crucial stage is to drill a second well close to the first to a similar depth of around 4.5 kilometres.

This closed circulatory system of two wells will bring even more heated water to the surface for heating in the local area and also allow the generation of electricity from the hot water.

Successfully completing the second phase will mean that the project will generate enough renewable energy for Eden to become carbon negative during 2023.

Eden Geothermal welcomes National Infrastructure Strategy as start of drilling approaches

Eden Geothermal welcomes the UK Government’s National Infrastructure Strategy

Rig secured and due to begin drilling 4.5km into hot rocks beneath Eden in the spring next year

Civil works gathering pace on the renewable geothermal energy site in Cornwall

Eden Geothermal Ltd (EGL) has welcomed the UK Government’s support shown for clean energy as part of the UK’s National Infrastructure Strategy. 

EGL is working with the Government and UK private investment to unlock the clean, geothermal energy deep in the granite beneath Cornwall.

Site construction works are now well underway, in preparation for drilling to commence in early Spring 2021, and a 450mt rig has been secured.

To drill its first well, EGL secured £16.8 funding million from a combination of ERDF, Cornwall Council and institutional funding from GCP Infrastructure Investments Limited, a company advised by Gravis Capital Management Ltd. This has increased to £17.3m of funding, in line with recent cost increases due to Covid – 19.

Work starts on site at Eden’s pioneering geothermal heat and power plant

Visitors and neighbours will soon be able to watch the project take shape from a special viewing area

New £20,000 Eden Geothermal Community Fund launched

Drilling 4.5km into hot rocks beneath Eden is now due to begin in early 2021

Work is about to begin on preparing the ground for Eden’s pioneering geothermal heat and power project at its Bodelva site. This is on land just inside the main Eden Project visitor gate and is a significant step in what Eden sees as a clean-energy revolution for Cornwall and the UK.

Drilling was due to start this summer but the project was held up due to the global pandemic.

Now neighbours have been informed that work will be starting from 21st September, with the first phase being the building of a hardstanding for the rig, connecting essential services, and putting in some temporary buildings and roadways within the site. This preparatory work is for the rig to be accommodated. When drilling starts, it is expected to take five months to reach the target zone 4.5 km down.

This week also sees the launch of the Eden Geothermal Community Fund, a £20,000 pot to support community environmental projects in four neighbouring parishes. Applications for projects will open in November.
