Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what assessment his Department has made of the (a) effectiveness and (b) costs of geothermal energy.

We know that to achieve net zero, we must look at how we can accelerate the potential of all low carbon technologies including geothermal. The Government understands that geothermal can play a role in our decarbonisation ambitions particularly as a low carbon source for heat via heat networks. We have commissioned research into the potential costs of geothermal heat in the UK and will use this to understand how the government can support the sector to achieve its potential.
