“Energy from waste water”, the renewable energy source for heating and cooling buildings, was also the topic of the International Conference “Decarb Cities Conference” held in Vienna at the end of February.
More than 50% of the energy consumption in the building sector is used for heating, and the subject of cooling is becoming increasingly important! Until now, almost exclusively CO2 critical energy sources have been used for this purpose. It is therefore essential to switch quickly to renewable energy sources. In this context, the energetic use of municipal and commercial waste water as a source of energy available all year round, around the clock – with a high temperature level compared to geothermal energy – is becoming increasingly important. Every household and business produces a large amount of wastewater every day. Wastewater is still considered a “dirty business” and often flows unused into the sewerage system.
However, “clean” energy can be easily and efficiently produced from this supposedly “dirty” water, making a significant contribution to the decarbonisation of cities.
We were there with a presentation by Dr. Rainer Wiedemann on the possibilities and technologies for obtaining energy from wastewater. Our boss also took part in a top-class panel discussion on this topic.
