Dunelm Geotechnical has started drilling a trial borehole to investigate renewable heat in Plymouth.
The work involves drilling a 100m trial borehole to investigate renewable heat from the limestone seams on land outside Plymouth Civic Centre.
According to Plymouth City Council, this geothermal energy source has the potential to heat and cool buildings at lower cost and reduced impact on the environment.
Plymouth City Council cabinet member for finance Mark Lowry said: “We have pledged to seek out renewable energy sources within our city. As we have recently heard from the UN Intergovernmental Panel on Climate Change, we all need to play our part in preventing rising global temperatures.
“This is a very early step in our search for fossil fuel alternatives in Plymouth, and has the potential to be very exciting.”
The council will have a clear idea of how effective this source could be later this year, and if successful a number of wells will be drilled to begin extracting the heat and provide cooling.
The works will cost £25,000 and are part of an EU funded project called Heatnet.
