This paper presents the results of technical-economic comparative analysis of two energy storage systems integrated withwind farm: Power-to-Gas-to-Gas Grid (Case A) and Power-to-Gas-to-Power (Case B). The aim of the technical analysis wasto determine the power characteristics of particular installations forming the storage systems and the assessment impact ofnominal power of hydrogen generators on basic technical indicators, which can influence on the investment decision. As partof the economic analysis the impact of the grants level, the sale price of product and the purchase price of electricity on theNPVR (Net Present Value Ratio), depending on the nominal power of hydrogen generators, was analyzed. The break-evenunit investment costs for both cases with a nominal power of hydrogen generators of 5 MW depending on the purchase priceof electricity and the sale price of the main product were determined.
