The Anonymous Widower

Mine Water Heat

The title of this post, is the same as that of this press release from the Coal Authority.

This is the introductory paragraph.

The Coal Authority is working with partners to unlock the heat within our historical coal mine network, to transform the homes and workplaces of the future.

The Coal Authority doesn’t have much of a historic product, so selling the heat from the mines could be an environmentally-friendly revenue scheme.

These four paragraphs are the heart of the press release.

As part of our work to make a better future for people and the environment in mining areas, we’re exploring opportunities to use mine water to heat and cool homes and businesses.

Water within the mines is warmed by natural processes and can, if sustainably managed, provide a continuous supply of heat. Mine water temperatures are not affected by seasonal variations and, subject to the right support, mine water can provide renewable, secure, low carbon heating for buildings in coalfield areas.

With heating accounting for 40% of energy use in the UK, mine water heat could improve the sustainability of the places where we live and work. Mine water heat could also play a part in the UK’s efforts to tackle climate change and support its net zero future.

The Coal Authority are working with academics, local authorities, central government and others to help realise the potential of mine water heat. We’re supporting the delivery of mine water heat projects and working with others to make them happen.

The press release then adds more details and describes specific projects.

Mines For Storing Electricity

We also mustn’t forget other uses for abandoned coal mines.

I particularly like Gravitricity’s idea of used abandoned deep mines to store energy, that I wrote about in Gravitricity Explores Czech Coal Mine For MW-Scale Storage.

I hope the Coal Authority has its eyes on this ball.

Conclusion

I first became aware of the ability to extract heat from abandoned coal mines at a lecture at the Geological Society of London, after which I wrote Can Abandoned Mines Heat Our Future?.

I believe that for some parts of the country, this could become the preferred technology for heating homes and businesses.

The technology was even featured on the BBC tonight.

  1. An interesting idea, the town I grew up in – St Helens – had mining industry and various of my older family members were miners. A good use of the spent mines, and it occurs to me that they may be less interesting to terrorists because they would be hard to get at.
