Abstract

In this report a survey of different techniques for storage of electrical energy. The following alternatives are described regarding method, characteristics, potential and economy. Batteries; Capacitors; Flywheels; Pump storage hydro power plants; Hydrogen gas generation; Air compression. Regarding evaluation of methods for storage of electrical energy. Battery storage: The development of Lithium-ion batteries are of great interest. In the present situation it is however difficult of classify battery storage as a good alternation in applications with frequent re-charging cycles and re-charging of large energy volumes. The batteries have limited life length compared to other alternatives. Also the power is limited at charging and discharging. Energy storage in capacitors: 'Super-capacitors' having large power capacity is considered to be of interest in applications where fast control of power is necessary. The ongoing development of based on carbon-nanotubes will increase the energy storage capacity compared with the today existing super-capacitors. This can in the future be an alternative to battery storage. Of further interest is also the idea to combine battery and capacitor based storage to achieve longer life-time of the batteries and faster power control. Flywheel energy storage: The energy storage capacity is relatively limited but power control can be fast. This  More>>

Batteries; Capacitors; Flywheels; Pump storage hydro power plants; Hydrogen gas generation; Air compression. Regarding evaluation of methods for storage of electrical energy. Battery storage: The development of Lithium-ion batteries are of great interest. In the present situation it is however difficult of classify battery storage as a good alternation in applications with frequent re-charging cycles and re-charging of large energy volumes. The batteries have limited life length compared to other alternatives. Also the power is limited at charging and discharging. Energy storage in capacitors: 'Super-capacitors' having large power capacity is considered to be of interest in applications where fast control of power is necessary. The ongoing development of based on carbon-nanotubes will increase the energy storage capacity compared with the today existing super-capacitors. This can in the future be an alternative to battery storage. Of further interest is also the idea to combine battery and capacitor based storage to achieve longer life-time of the batteries and faster power control. Flywheel energy storage: The energy storage capacity is relatively limited but power control can be fast. This system can be an alternative to capacitor based energy storage. Pump-storage hydro power plant: This type of energy storage is well suited and proven for time frame up to some days. In the Swedish power system there is today not any large demand of energy storage in this time frame as there is a large capacity in conventional hydro power plants with storage capacity. Pump-storage can however be of interest in the southern part of Sweden. In some operation stages the grid is loaded up to its limit due to large power transmission from the north. The pump-storage can reduce this power transfer during critical periods and can therefore be an alternative to new power lines. Hydrogen energy storage: The handling (storage and transfer) of hydrogen is considered to be difficult and dangerous. Air-compression energy storage: This method is combined with gas turbine plants. During periods with surplus of energy in the power system this surplus energy is used to compress air and store it. This compressed air is used in the operation of gas turbine power plant where the compressed air is used instead of the normal use where the gas turbine makes the compression. The possibility should be considered in the future if new gas turbine power plants are to be built in Sweden. This is not the situation today. Different application areas where the energy storage can be used are discussed, such as: Electrical supply quality improvement; Improvement of power system transient stability; Damping of electromechanical oscillations in the power system; Spinning disturbance power reserves; Power system frequency control; Fast disturbance power reserves (activated within 15 minutes); Optimization of energy production dispatch; Increase of power grid transmission capacity. In the scientific world the technical development is very active within areas regarding batteries, capacitors with very large storage capacity, flywheels, etc. As the progress is very fast and this report gives only a brief survey of the research within the area, there is a need to continuously follow the technical development. The judgement is done that there is demand for evaluation of the value of energy storage for different applications and to identify suitable methods to be used in the different applications. Regarding conditions and demands in Sweden and the other Nordic countries research and development activities should be done as: Identify application areas where there are requirements of improvements in the power system. From the identified demands it should be analysed if electrical energy storage can be used to achieve the required improvements. For each application area different alternatives for energy storages are evaluated regarding technical feasibility, environmental influence and economy. During the next 2-4 years conceptual solutions should be presented for application where electrical energy storage is considered to be technically and economically feasible. These applications should be linked to new requirements in the power system due to increased volume of distributed power generation (for example wind power), increased consumptions of electrical energy due to new load objects (for example electrical cars), changed structure of the distribution grids, etc. Evaluation of the different concepts is done as soon as the above described conceptual studies allow. Prioritization of realization should be done. Within 5 years from now realization of pilot projects are started.}
