Can photovoltaic and biogas be integrated in a WWTP?

Integrating renewable energy sources, biogas, and solar energy could provide up to 88% of the annual energy requirements of WWTPs. Recommendations are provided for further research considering the limited availability of integrated resources for studying the simultaneous utilization of photovoltaic and biogas systems. 1. Introduction

What is the current state of solar PV systems in WWTPs?

Strazzabosco et al. (2019) assessed the current state of solar PV systems in WWTPs and found that solar PV is primarily used in hybrid configurations with anaerobic digestion at WWTPs with flow rates greater than 1.89 × 10 4 m 3 /d. In these treatment plants, biogas meets 25%–65% of the total energy demand, and solar energy supplies 8%–30%.

Can solar PV be used at a WWTP?

At WWTPs with flow rates less than 1.89 × 10 4 m 3 /d, solar PV provides 30%–100% of the required energy and is typically used as the sole RES. On the other hand, most studies examining the applications of PV cells at WWTPs have focused on the conventional fixed-beam-supported technology.

Is solar photovoltaics sustainable?

Solar photovoltaics is a common solar technology that has a high potential to meet global energy demand and significantly impacts the transition to sustainable energy by reducing carbon emissions from WWTPs by 10%–40%. However, solar PV deployment requires expansive land areas ( Chen and Zhou, 2022; Claus and López, 2022 ).
