Geothermal energy advantages, disadvantages and UK incentives

At the present time, ground source heat and other forms of geothermal energy exploitation are an under-appreciated method for clean energy collection. This could change in the near future, as cost-effective technologies are becoming more widely available. 

Major advantages:

  • Highly efficient and reliable
  • Direct heat transfer – no fuels
  • Excellent for base load demand

Major limitations:

  • Requires electricity to power the pumps
  • High expenditure of water
  • The installation process can be disruptive

Available incentives in the UK:

  • Renewable Heat Incentive (RHI) – this scheme rewards non-residential and residential properties that use renewable sources of heat, and ground source pumps fall within its auspices. It is operated in a very similar fashion to FIT, except that it remains open for new participants until 2021, at which point the scheme will either be extended, or replaced with a different version of the program, or terminated.
