Mass Energy Storage System

As the demand for energy increases worldwide, the use of fossil fuels and continuous emission of CO2 has caused pollution and global warming. In order to suppress greenhouse gas emission, renewable energy such as solar energy, wind energy and fuel cell, is receiving spotlight and is being disseminated at a fast speed. However, renewable energy is highly affected by location environment and natural condition, so there is a lot of fluctuation in its output. Therefore, it is difficult to provide the energy continuously and a time lag occurs between when the energy is produced and when it is demanded. Mass energy storage system is considered to be a solution to these problems.

Energy storage system (ESS) is a power feeding equipment that stores excess energy and supplies it when needed; thus increasing energy effectiveness, utilization of renewable energy, as well as stabilizing energy supply. Hence, as ESS can perform the role of 'electricity reservoir,' that stores surplus electricity and reuse it, it is useful during times of blackout as emergency power source and also can be helpful managing electric power load.

Regarding its use, mass secondary battery storage system is at the center of large-scale solar power generation and wind power developing district, while in the cases of electricity surplus or underload during night time, compressed air or fly-wheel can be applied. Especially on smart-grid, the energy storage system is becoming increasingly important, particularly the secondary battery is efficient as it can respond quickly depending on system conditions.? Thus, energy storage system is a newly emerging industry whose market is expected to grow substantially as it is the key technology in the green industry that creates value such as stabilization of electric supply and dissemination of renewable energy.

Among diverse types of energy storage system, Redox Flow Battery, one that is most suitable for large-scale energy storage system, will be looked at in detail.

Redox flow battery

Unlike other secondary battery that stores electric energy in the electrode that includes active material, redox flow battery is a electrochemical energy storage system that charges and discharges as the active material in electrolyte goes through redox (reduction/oxidation) process and directly stores the chemical energy of active material as electric energy.

The redox flow battery comprises of electrolyte tank that decides the capacity of active materials with different oxidation levels, pump that circulates active materials during charging and discharging process, as well as stack that is?in charge of the output. As the electrolyte tank and stack are separated, it is possible to freely design its output and capacity, and the constraint put on installation location is little. Also, the battery does not produce waste such as CO2 and the vanadium active material, one of electrolytes, can be used semi-permanently, making a very efficient use of resources.

As active material of a redox flow battery, electrolytes produced by liquidating transition metals such as V, Fe, Cr, Cu, Ti, Sn, Zn and Br in strong acid are generally used, and operating voltage is determined through the potential difference between anode and cathode active material. In order to obtain wanted voltage and electric current, stack is connected in a series or parallel circuit and then laminated.

Redox flow battery is free in planning its output and capacity as well as stable since it operates in room temperature. It can also be used for a long period time -over 10 years- but has low output density and energy density.
