"Energy from wastewater", the renewable energy source for heating and cooling buildings, was also a topic at the international "Decarb Cities Conference" in Vienna at the end of February.
Over 50% of energy consumption in the building sector is used for heating, and cooling is also becoming increasingly important! To date, almost exclusively CO2-critical energy sources have been used for this purpose. It is therefore important to switch quickly to renewable energy sources. In this context, the use of municipal and industrial wastewater as a source of energy that is available all year round, around the clock - at 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 matter" and often flows unused into the sewage system.
However, this supposedly "dirty" water can be used to generate "clean" energy very easily and efficiently, making a significant contribution to the decarbonization of cities.
We were there with a presentation by Dr. Rainer Wiedemann on the possibilities and technologies for generating energy from wastewater. Our boss also took part in a high-caliber panel discussion on this topic.
