Abstract:
Deep geothermal needs a high enough T for co-generation – power + heat.
And we need to drill at least 3-4 km deep to get 60-70°C.
Shallow geothermal (GSHP) becomes inefficient because the ground cools more and more each year.
But if the shallow ground T is OK and is maintained annually – heat pumps have a COP of 3 to 4!! Good use of power.
