Islay Energy Trust study heat from the sea

Islay Energy Trust have recently completed a feasibility study for a water source heat pump using heat from the sea. Working as part of the GeoAtlantic project, they have undertaken research to examine how Loch Indaal (a sea loch) could be used as a heat source for homes on the islands of Islay, Jura and Colonsay off the west coast of Scotland. 

In the same way that ground source heat pumps use a heat exchanger buried in the ground to extract heat, water source heat pumps use a heat exchanger submerged underwater. The heat pump technology itself is exactly the same.

The majority of water source heat pumps in use today utilise fresh water sources. The Trust’s research is a move towards understanding more about the potential of harnessing heat from the sea, with a focus on remote rural areas. This could prove very useful for coastal communities in Cornwall.

Findings will be published over the coming months. However, a precursory event ‘Heat from the Sea: Could Lochindaal heat our homes?’ will take place at Islay Nature Centre in Port Charlotte on Tuesday 23rd of July at 7.30pm, in partnership with the Islay Natural History Trust.

South West Georesources Partnership

We recently attended the South West Georesources Partnership meeting.

“The aim of the Partnership is to enable the strategic and sustainable development of the georesources of South West England. The Partnership is an independent hub, which will co-create a powerful public vision and strategy.

The Partnership will deliver guidance for all stakeholders, based upon an informed, aligned, balanced and shared position, which builds on and compliments the ongoing work by existing groups: all embracing the region’s abundant natural georesources – its minerals, metals, construction materials, geothermal energy and soils. As a regional, cross-boundary group, this local initiative will provide a cohesive voice which will set an example of good practice and aim to lead the national agenda for georesource stewardship.”

Welcome to GeoAtlantic Cornwall!

Welcome to the new ‘GeoAtlantic Cornwall’ website. As part of the wider GeoAtlantic project, this site is focused on the work being done in Cornwall by the University of Exeter; one of the GeoAtlantic project’s UK partners.

The site will contain news & updates on all things geothermal going on in Cornwall, as well as resources outlining some of the technologies involved. As part of this aim to promote and disseminate the latest developments, many of the activities outlined are being carried out by organisations separate to the GeoAtlantic project – we are simply promoting their work.

If you have any questions about the GeoAtlantic project, or geothermal energy in general and how it could benefit you, please do not hesitate to get in contact.
