What is the economic model for vanadium redox flow battery?

A techno-economic model for vanadium redox flow battery is presented. The method uses experimental data from a kW-kWh-class pilot plant. A market analysis is developed to determine economic parameters. Capital cost and profitability of different battery sizes are assessed. The results of prudential and perspective analyses are presented.

Does reselling vanadium electrolyte preserve its operative value?

In addition, the vanadium electrolyte after regeneration preserves its operative value because it is not affected by cross-contamination and aging effects. However, no market quotations are available at present for vanadium reselling, so that in a prudential analysis it was assumed EOL cost equal to zero, consistently with most literature [13, 23].

Is EoL cost a Prudential assumption for vanadium reselling?

However, no market quotations are available at present for vanadium reselling, so that in a prudential analysis it was assumed EOL cost equal to zero, consistently with most literature [13, 23]. A more favorable hypothesis is made in the perspective analysis. 4. Results 4.1. LCOS and NPV with prudential assumptions

Are VfB batteries profitable for E/P?

The latter figures made VFBs profitable for E/P in the range of 4–10 h. As a final comment, it is worth noting that VFB s are sold for extremely long cycle lives, which extend beyond 20 years of operation, unparalleled by other types of batteries.

What are the parameters involved in a power system model?

Some of the parameters involved in the model are related to the system performance, such as power density and efficiency, while others depend on the market conditions, such as component costs, electricity price and discount rate.
