The aim of the technical analysis was to determine the power characteristics of particular installations forming the storage systems and the assessment impact of nominal power of hydrogen generators on basic technical indicators, which can influence on the investment decision. As part of the economic analysis the impact of the grants level, the sale price of product and the purchase price of electricity on the NPVR (Net Present Value Ratio), depending on the nominal power of hydrogen generators, was analyzed. The break-even unit investment costs for both cases with a nominal power of hydrogen generators of 5 MW depending on the purchase price of electricity and the sale price of the main product were determined.
