How much does VfB cost?
The latter is a more complete, though somewhat neglected, economic indicator as it is detailed further on. In this framework, several recent economic analyses indicate for VFB s a capital cost in the range of 300–800 € kWh −1 (or even less) and a LCOS ranging as 0.1–0.5 € kWh −1 cycles −1 [23, 24].
How to evaluate the profitability of VfB systems?
To evaluate the profitability of VFB systems, a lifespan must be assumed. This is not usually the working life of the equipment, nor it is the time over which the capital investment is recovered. It is rather a period over which the profitability of different projects can be compared.
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.
How many vfbs are there in the world?
VFBs are already marketed, with 27 producers worldwide and the global vanadium organization VANITEC in listing the plants installed globally accounts for a total power capacity exceeding 500 MW and energy capacity above 1.5 GWh .
What are the economic parameters used in the analysis of VfB systems?
Economic parameters Table 4 lists the most important techno-economic parameter used in the analyses. The number of cells per stack is 40, the same value of the stack experimented in and a typical value of industrial stacks. To evaluate the profitability of VFB systems, a lifespan must be assumed.
How much value does a VfB have at end of life?
In particular, published life cycle assessments show that VFBs at end of life maintain 70% of their value and only 30% of the component investment must be spent to obtain a second life battery [13, 23, 47].
