United Downs Deep Geothermal Project Confident On Potential Power Generation

The title of this post is the same as that of this article on ThinkGeoenergy.

This is the first paragraph.

With initial tests of the well drilled, the United Downs Deep Geothermal Project (UDDGP) suggests that the project will be able to generate electricity of as much as 3 MW in power generation capacity.

Two holes have been bored to a depth of 5 km.

If the project is successful, up to three MW of heat could be brought to the surface, which can be used to generate electricity or heat buildings.

A Look At Possible Costs

This page on Wikipedia is entitled Cost Of Electricity By Source.

It gives these for the capital cost of power stations for various zero-carbon energy sources.

  • onshore wind – $1600/kW
  • offshore wind – $6500/kW
  • solar PV (fixed) – $1060/kW (utility) $1800/kW
  • solar PV (tracking)- $1130/kW (utility) $2000/k
  • battery storage power – $2000/kW
  • conventional hydropower – $2680/kW
  • geothermal – $2800/kW

Geothermal has one big advantage over wind and solar power in that it is a continuous power source like nuclear, hydropower and some fossil fuels, so it doesn’t need to be backed by energy storage.
