Thermoelectrics is a business impeded by the use of the toxic rare metal Tellurium. Commendably, there is a trend to alternatives in research but few volume sales as yet in any of the three uses. These are energy harvesting to make electricity where it is needed and the more successful cooling and heating, those last two constituting very-reliable, solid heat pumps.

Thursday 26 August 2021 - Why is even seasonal storage a new requirement? How is it that storage by compressed air, gravity and other non-battery options closely leverage mine assets for greater safety and viability? Why does next generation solar fit so well in mines? and more.

Imagine mines with so much electricity production and storage that they do far more downstream processing. As reserves deplete, many will even transition to being zero-emission power stations and electricity storage for local communities and industry or even national grids. The cost of making-good becomes income from reinvention. That is the untold story of mining electrification, beyond the vital safety, greening, and cost reduction of electrics.
