Abstract
The transition to renewable energy depends on effective storage. A redox flow battery (RFB) is a greener battery in which energy is stored in liquid electrolytes pumped through a cell that cycles between chemical redox states. This thesis examines a bench‑scale system using phoenicin, a compound derived from fungi. We connected a solar photovoltaic (PV) panel directly to the RFB to test whether it could store real solar energy. We evaluated performance by comparing the battery’s capacity with the PV panel’s energy output; by measuring three efficiencies—coulombic (CE, how much charge is recovered), voltage (VE, how much voltage is lost), and energy (EE, overall efficiency); and by tracking capacity loss per cycle and per hour. The results show that a phoenicin‑based RFB can store energy from a PV panel at bench scale, provided certain adjustments are made relative to earlier quality‑checked RFB setups in this project. Overall, the work indicates that this type of RFB is a viable option for storing energy from renewable sources.
Overgangen til vedvarende energi kræver effektiv lagring. Et redox-flow-batteri (RFB) er et grønnere batteri, hvor energien lagres i flydende elektrolytter, der pumpes gennem en celle, som skifter mellem kemiske redox-tilstande. Denne afhandling undersøger et bænkskala-system baseret på phoenicin, en forbindelse udvundet fra svampe. Vi koblede et solcellepanel (PV-panel) direkte til RFB’et for at se, om batteriet kunne lagre den producerede solenergi under realistiske forhold. Ydelsen blev vurderet ud fra batteriets kapacitet i forhold til solpanelets energiproduktion, tre virkningsgrader – coulombisk (CE, hvor meget ladning der kan hentes ud igen), spændings- (VE, hvor meget spænding der mistes) og energi-virkningsgrad (EE, den samlede effektivitet) – samt kapacitetstab pr. cyklus og pr. time. Resultaterne viser, at et phoenicin-baseret RFB kan lagre energi fra et PV-panel på bænkskala, forudsat visse justeringer i forhold til tidligere kvalitetstjekkede RFB-opstillinger i projektet. Samlet set indikerer arbejdet, at denne type RFB er en realiserbar løsning til lagring af energi fra vedvarende kilder.
