Energetic securities, low environmental impact, accessibility to energy sources and depletion of fossil fuels have focused the attention on the use of renewable energy sources.
The use of renewable energy sources in tandem with fuel cells stack powered with hydrogen is the optimal solution of sustainable energy systems. This paper highlights the results of a comparative study regarding the energy support of an independent stationary application with renewable energy sources in Rm. Valcea. The first scenario analysed and optimised the system consisting of wind turbines, PEM fuel cell stack, hydrogen tank, electrolyser and converters. The second analysed and optimised system consists of PV panels, wind turbines, PEM fuel cell stack, hydrogen tank, electrolyser and converters.
The systems’ analysis and optimization was based on the evaluation of the following performance indicators: a) the amount of energy produced from renewable sources; b) the amount of hydrogen from the excess of energy provided by wind power and photovoltaic panels; c) quantity of emitted CO2; d) sizing of system equipment. On the other hand, the effects of parameters such as: wind speed, clearness index and solar radiation have also been assessed.
