Waste Not, Want Not - How Countries are Reusing Waste Heat - Part 2 - Heat from Other Sources and Ways to Store it
Capturing and Storing other Forms of Heat -Diagram created by ChatGPT Other Heat Sources Data centres aren’t the only producers of waste heat. It is generated by all sorts of activities and places including offices, hospitals, shops, institutions,and industrial activities. Indeed, collectively they contribute to making our cities hotter than the surrounding countryside and increase the need for services such as air conditioning and refrigeration. I have already discussed the use of High Temperature Incineration and Biogas (from farm and food waste) elsewhere and these are commonly used in co-generation for district heat, but here are some of the more unusual sources of waste heat which are being used for this purpose. Sewage Heat Scandinavian countries are no slouches either when it comes to capturing heat from treated sewage water. Treated waste water leaves sewage works at between 12 and 23 °C. and like data centre heat, must first be boosted to the right temperat...
