Abstract
Due to the random nature of the production, the use of renewable energy sources requires the use of technologies that allow adjustment of electricity production to demand. One of the ways that enable this task is the use of energy storage systems. The article focuses on the analysis of the cost-effectiveness of energy storage from the grid. In particular, the technology was evaluated using underground hydrogen storage generated in electrolysers. Economic analyzes use historical data from the Polish energy market. The obtained results illustrate, among other things, the proportions between the main technology modules selected optimally in technical and economic terms.
Highlights
Energy storage technologies make it possible to change the way electricity networks operate
The effect of such work may be an increase in the efficiency of electricity production of a conventional power plant, which may led to reduction in energy costs and a decrease in the production of electricity in peak systems
The day-ahead market of the commodity energy exchange was characterized in 2017. a small number of hours in which the price was much lower than the average and a small number of hours with the price significantly exceeding the average price
Summary
Energy storage technologies make it possible to change the way electricity networks operate. The electricity produced in these systems represents only 0.27% of the electricity produced in Poland, and their capacity is about 10GWh. The main reason for considering energy storage should be making a profit for the energy storage company. The effect of such work may be an increase in the efficiency of electricity production of a conventional power plant, which may led to reduction in energy costs and a decrease in the production of electricity in peak systems. Systems of this type can contribute to reducing emissions by enabling greater use of overproduction of energy from renewable sources. Out the main economic parameters for estimating the profitability conditions of this type of installation
