Description

The Vanadium Redox Flow Battery (VRFB) system is divided into two subsystems - a power and an energy sub-system - in accordance with the cell area related to the power and the electrolyte volume related to the energy storage capacity. Remaining components are assigned to the periphery. The considered VRFB system shows a rated power of 1 MW and an energy capacity of 8.3 MWh. The principal battery layout is derived from published literature, majorly a recent publication on stationary VRFB (Minke, C. Techno-ökonomische Modellierung Und Bewertung von Stationären, Vanadium-Redox-Flow-Batterien Im Industriellen Maßstab, 40th ed.; Cuvillier Verlag: Göttingen, 2016). The dimensions of the different parts provided there allow for calculating the battery composition on a mass basis. An 8.3 MWh system requires an electrolyte volume of 194 m3 and, assuming a void volume of 50%, a tank capacity of 300 m3. For a nominal power of 1 MW, two stacks with a total of 155 cells are required. Each stack is composed of a 105 membrane, a bipolar plates, two carbon felt electrodes, two current collector and the two associated gaskets.

Quality and maturity

TRL scale Higher is more mature. 9: routine commercial deployment 8: commercial, but still niche or scaling 7: first-commercial or advanced demonstration 6: engineering-scale demonstration 5: pilot or large prototype 4: bench or lab validated 3: research-stage concept Technology readiness level
1 to 5 scale Lower is better. 1: strong market- or operating-data basis 2: commercially plausible, but still somewhat specific 3: partly representative, with modelling or adaptation bias 4: pilot, proxy-based, scaled-up, or prospective 5: weak representation of the real technology state Technological representativeness
1 to 5 scale Lower is better. 1: geography matches the claimed scope well 2: regionally credible, but broader or less exact 3: generic regional or global proxy 4: weak proxy or clear geographic mismatch 5: geography is effectively unsupported Geographical representativeness
1 to 5 scale Lower is better. 1: current for that technology class 2: slightly dated, but still good 3: dated enough to need caution 4: stale, pilot-era, or prospective relative to current practice 5: clearly not representative of the current state Temporal representativeness

Missing exchange uncertainty generation: Not requested

Representativeness scores use a 1–5 scale when provided. Lower scores indicate a closer fit to the modeled technology, geography, or time period.
