This article proposes and analyzes a new solar driven cogeneration to produce power and liquefies natural gas (LNG) base on organic Rankine cycle (ORC). The desired system is integrated with linear Fresnel solar collectors (LFC) to provide the required energy. Exergoeconomic and exergoenvironmental concepts are used to analyze the system. The major design parameters are considered to assess the cost and environmental impact (EI) performances of the system. Parametric assessment indicates that TUR-2 inlet pressure has the highest positive effect on the EI rate of system within 0.2% while TUR-2 back pressure increment affects the cost performance of the overall system drastically among the other parameters by about 1.8%.
