The influence of the foundation is marginal compared to the electrolyte. In the 10 considered impact indicators, this leads to a reduction of emission between 0.97% (ODP) and 91.8% (AP). On average, a VFB using reprocessed vanadium electrolyte instead of primary electrolyte has only 53% of potential environmental impacts.
Alternatively, vanadium can be sold to the iron and steel industry which sums up 80% of the whole vanadium demand, in a market trend where the production of vanadium is constantly increasing, from 35,000 t in 1994 to almost 90,000 t in 2020 .
It is widely anticipated that the vanadium electrolyte may be reused in several life cycles. Thus, a fair allocation of the primary electrolyte's emissions over the life cycles is desirable. In this work, emissions of primary vanadium electrolyte are equally divided over the primary and subsequent reuse life cycles.
The testing procedure presented in Ref. can constitute a standard approach for the performance assessment of kW-class VFBs, which at present is lacking, and can contribute to the definition of performance parameters for the comparison of different All-vanadium redox flow batteries .
