Wind power is characterized by high variability and unpredictability. Due to limited opportunities for electricity storage and the power grid’s limited carrying capacity, an increase in the use of renewable sources may bring about unfavorable technical and economic consequences. Energy storage systems may mitigate the negative effects of electricity generation in wind power plants. Energy storage systems can also aid the cause of clean coal technologies, by increasing working time and efficiency and reducing CO2 emissions in coal power plants. This paper presents a simplified model of a system of energy storage in the form of hydrogen. Hydrogen is produced through electrolysis and is stored in underground storage sites. A hydrogen-fired gas turbine is used in the process of chemical energy-to-electricity conversion. Calculations are performed to determine hydrogen mass and volume flow needed for storage to make up for the insufficient amounts of electricity produced over time. A preliminary economic analysis for various power storage systems is also presented.
