With the well-documented long-term effects that conventional sources of energy have on the climate and the environment, it is of utmost priority to move toward sources of fuel that have minimal impact on our surroundings and, on top of that, to produce them in a way that is sustainable. As the energy sector is the major contributor to greenhouse gas emissions, the emphasis is on making this sector more sustainable and producing energy from sources that are green and renewable. The current study aims to design a new solar and wind hybrid system in which a wind turbine and a parabolic trough collector (PTC) operate a trigeneration system to produce electric power, green hydrogen, and provide cooling. Duratherm 600 oil is used as a heat transfer fluid in the PTC, and a wind turbine with a specification of G14-0.5 is employed to run the trigeneration system to produce electricity. The electricity produced by the combination of the wind turbine and the PTC is split into three parts: the first part is fed directly to the electric grid, the second is used to run an electrolyzer to produce green hydrogen (via water electrolysis), and the third part is used to provide cooling (through a vapor compression cycle). The hydrogen produced is fed to a fuel station to be used as fuel for vehicles. The cooling produced by the vapor compression cycle is used to preserve food and milk and provide room comfort. The effects of several factors, such as direct normal irradiation (DNI) and wind speed, are also studied. The results show that for an optimum DNI of 800 W/m2 and wind speed of 10.8 m/s, the energetic and exergetic efficiencies were 35.5% and 20.8%, respectively.
