Storage system for electricity obtained from wind power plants using underground hydrogen reservoir

Sebastian Lepszy, Tadeusz Chmielniak, Paweł Mońka


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.
