Dr Gareth Farr (BGS) will present on “Low enthalpy ground source heating in Wales: baseline mapping and operational systems utilising abandoned coal workings and shallow urban aquifers” at the joint Geothermal Association of Ireland/IAH TDM.

Abstract:

Gareth Farr (British Geological Survey) will be talking about harnessing low enthalpy heat from urban groundwater systems and abandoned mines in Wales. The talk will outline work in two contrasting hydrogeological environments namely the South Wales Coalfield (flooded underground mines) and the City of Cardiff (shallow gravel aquifer influenced by the subsurface urban heat island effect). In both areas trial systems have been constructed and now work is underway to upscale these into integrated heat networks. There are technical, regulatory and societal challenges that need to be overcome to ensure ground source heating can become more of a mainstream way to generate heat, increase energy security and decrease fuel poverty. This work has been undertaken with a range of partners including; Cardiff Universities Geoenvironmental Research Centre (GRC), City of Cardiff Council and WDS Green Energy.

Venue: Geological Survey Ireland, Beggars Bush, Dublin 4

Date: Tuesday 7th February 2017

Time: Tea/Coffee 17.30; lecture 18.00 hrs.
