Hamburg’s industrial waste heat project: a model for climate-neutral district heating?  In Hamburg, a pioneering energy project is showing how cities can become climate neutral by capturing heat that would otherwise go to waste. By using waste heat from copper production, the city now supplies clean heat to its district heating system. Could this be a model other cities follow?  In partnership with the European Commission  READ MORE : http://www.euronews.com/2025/07/21/hamburgs-industrial-waste-heat-project-a-model-for-climate-neutral-district-heating  Subscribe to our channel.

00:00Before collecting the heat and using it for district heating, the heat was just

00:09cooled down. So we took water from the river Elbe and cooled down the heat that

00:14came from the process and it was used for nothing. It was just wasted. Then when in

00:20Hamburg a whole new district was built, we had this idea to work together with

00:25Anna City who came to us to use the heat for warming households. In order for the

00:33project to be working we needed a total retrofitting of the contact plant where

00:38the sulfuric acid is produced and we needed this big heat exchanger, pumps, pipes

00:44and all these things. Very special steel and stones being able to absorb the heat

00:52combined with the with the acid. What would help to make it more economically

00:58feasible and maybe to make other industries follow our example would be if

01:05you could could incentivize producing or using it's it's already there using this

01:12CO2 free heat by for example providing free allocations in the European emission

01:18trading system or developing some kind of green markets.
