Die Potenziale der Energieeinsparung in der Abwasserwirtschaft

Abstract

Welche Potenziale birgt die Abwasserwirtschaft im Sinne der Klimaschutzziele? Und welche rechtlichen Rahmenbedingungen sind dabei zu berücksichtigen? Durch innovative Ansätze sowie die Einbindung in den Energiemarkt können erhebliche Effizienzpotenziale ausgeschöpft werden.

Implications of the Interrelations between the (Waste)Water Sector and Hydrogen Production for Arid Countries Using the Example of Jordan

“…Apart from H 2 O, other feedstocks exist in the wastewater sector from which hydrogen can be produced. As regards sewage sludge, one can differentiate between thermochemical processes (e.g., pyrolysis, gasification) and biological processes (e.g., dark fermentation, photo-fermentation) to be applied for hydrogen production [64,88]. As of 2019, Liu et al found that, generally, reaction rates are faster for thermochemical processes, resulting in higher hydrogen yields [60].…”

“…The role of wastewater has been touched upon only very recently, especially by research from Australia [55,[58][59][60]. However, German research has also investigated the different options of hydrogen production at wastewater treatment plants (WWTPs) [61][62][63][64]. Then, very often, the question is raised about how electrolysis-based oxygen can be used in wastewater treatment processes to also reduce the overall OPEX [58,63,64].…”

“…However, German research has also investigated the different options of hydrogen production at wastewater treatment plants (WWTPs) [61][62][63][64]. Then, very often, the question is raised about how electrolysis-based oxygen can be used in wastewater treatment processes to also reduce the overall OPEX [58,63,64]. Although limited, just as important are the studies that investigate the water demand for equipment production and for the operation of auxiliary technologies, such as photovoltaic, to produce electricity to run electrolyzers or similar technologies [65,66].…”
