Today’s Solutions: October 24, 2021

If you frequently commute via the metro, you’ve probably noticed the hot gusts of air that tend to blow out of train tunnels. In London, a new project seeks to harness the heat from the underground metro in order to heat homes in the north of the city during the colder months of the year.

The project, which will start piping heat from the underground into homes and businesses later this year, is one of a growing number of schemes across the UK designed to warm homes using “waste heat” from factories, power plants, rivers, and disused mine shafts.

If successful, the tube project could pave the way for district heating schemes across the capital to warm homes with cheap, low carbon heat from underground lines.

This story was one of the best from 2019, and we are happy to include it in our “12 Days of Optimism” as we welcome in the new year!
