Bu aracın haberini elbet birçok arkadaşımız gazetelerden okumuştur.200 Lt tuzlu su ile 600 km yol yapan 920 bg gücündeki bir spor araba.

Benim aklıma takılan nokta araç gerçekten sadece tuzlu su sayesindemi çalışıyor yoksa su sadece bir enerji tutucu görevi görüyor da araç normalde elektrikle falan mı çalışıyor. Kimyacı arkadaşlar beni bir aydınlatırsa sevinirim.

Redox flow batteries, and to a lesser extent hybrid flow batteries, have the advantages of flexible layout (due to separation of the power and energy components), long cycle life (because there are no solid-solid phase transitions), quick response times, no need for "equalisation" charging (the over charging of a battery to ensure all cells have an equal charge) and no harmful emissions. Some types also offer easy state-of-charge determination (through voltage dependence on charge), low maintenance and tolerance to overcharge/overdischarge.

On the negative side, flow batteries are rather complicated in comparison with standard batteries as they may require pumps, sensors, control units and secondary containment vessels. The energy densities vary considerably but are, in general, rather low compared to portable batteries, such as the Li-ion.

Flow batteries are normally considered for relatively large (1 kWh – 10 MWh) stationary applications. These are for:

[list]
[*]Load balancing - where the battery is connected to an electrical grid to store excess electrical power during off-peak hours and release electrical power during peak demand periods.
[*]Storing energy from renewable sources such as wind or solar for discharge during periods of peak demand.
[*]Peak shaving, where spikes of demand are met by the battery.
[*]UPS, where the battery is used if the main power fails to provide an uninterrupted supply.
[*]Power conversion - because all cells share the same electrolyte/s. Therefore, the electrolyte/s may be charged using a given number of cells and discharged with a different number. Because the voltage of the battery is proportional to the number of cells used the battery can therefore act as a very powerful DC/DC converter. In addition, if the number of cells is continuously changed (on the input and/or output side) power conversion can also be AC/DC, AC/AC, or DC/AC with the frequency limited by that of the switching gear.[24]
[*]Electric vehicles - Because flow batteries can be rapidly "recharged" by replacing the electrolyte, they can be used for applications where the vehicle needs to take on energy as fast as a combustion engined vehicle.
[*]Stand-alone power system - An example of this is the telecom industry for use in cellphone base stations where there is no grid power available. The battery can be used alongside solar or wind power sources to compensate for their fluctuating power levels and alongside a generator to make the most efficient use of it to save fuel.[/list]
