    Abstract

    Nowadays, in light of climate change and global warming, many countries tend to increase the use of renewable energy. This shows an opportunity for dessert countries such as the UAE to maximize the use of solar energy and try to benefit from it. Cement industries are considered to be one of the main contributors to GHG emissions. The global usage of cement is rising rapidly, resulting in huge pollution. Thus, this research defines the concept of sustainability by integrating renewable energy in cement plants. This thesis presents a methodology for mapping the energy requirement and optimizing a plant that depends on solar energy and reduces the need for fuel. A review of cement processes was conducted to study the steps of cement manufacturing. A model that maps the energy requirements and CO2 emissions was developed to study the energy consumption for each step. Then, the model was validated using data from an active cement plant in UAE. The demand-side management option was evaluated by using PV panels to produce electrical energy to power the plant and CSP system to produce thermal energy that substitutes 40% of the fuel used. The electrical and thermal demands of the cement plant was used as an input to a linear optimization model to find the required installed capacities for PV, CSP, battery storage, and thermal storage. The capacities for PV, CSP, battery and thermal storages were founded to be 0.53132 GW, 0.65342 GW, 1.03876 GWh, and 6.18484 GWh, respectively. Then, techno-economic analysis was done using cost-benefit analysis for two scenarios to obtain the better option.
