Think of it like upcycling, for energy generation.
Engineers and scientists across the UK are looking at innovative sources to heat commercial and industrial buildings. In London, the plan is to take heat generated by the Thames, the Tube, and sewer networks to create a large heat network to feed into public buildings in the country’s capital.
There isn’t anything new about this, you might have heard of district heating before. What’s changed is the attention and money now on offer, and the realisation of just how essential it is we find low and no carbon heating and energy options, at low costs. Heating networks allow us to do more with what we are already using, or generating, with less waste.
