| dc.description.abstract | The global population explosion accompanied by industrial and technological expansion demand an increasing rate for energy consumption, especially, in form of electricity. That urges the search for clean energy sources to reduce the pollution caused by fossil fuel. The clean (or renewable) energy sources are of intermittent nature that can’t obey stable provision of electricity to our communities, and can’t be sure to follow the peak of electricity demand. To bypass the problem of intermittency and to synchronies between energy production and utilization, an energy storage system must be applied. Different energy storage systems are used, like batteries, pump hydro-energy storage system (PHES), etc. The current thesis aim to design an energy storage system for Nablus western wastewater treatment plant located in Deir Sharaf. The plant consumes a huge energy of about 2,261,762 kWh annually. The PHES system was chosen as a storage system. To achieve the requirements for such storage system two reservoirs of water were needed each of them has a capacity 24000 m3, a pipe connects between the above reservoir and the below reservoir of 310 m long and DN 630 mm and a reversible Francis turbine of 563 kW. To accommodate such design in wastewater treatment plant a comprehensive study of economic feasibility and environmental impact is needed. This can be accomplished by life cycle assessment (LCA) by which we can assess the construction environmental impact. The LCA was conducted by using openLCA 1.4.2 software. The software includes a CML baseline method which include 10 categories of environmental impact. Five phases of PHES design; production, transportation, excavation, maintenance and disposal or recycle phase, were underwent LCA according to ISO 14040. The results of environmental impact of production phase of PHES assessed by LCA were compared with lead acid battery storage system within the same range of life span and storage capacity, in addition to the capital cost between two storage systems. For PHES phases, it was found that the Production phase carries the highest environmental impacts, followed by the End of life phase and maintenance Phase. The excavation phase and the transportation phase always represented a negligible contribution. The results of comparison between the production phases for the two systems was found to be a higher impact for climate change and acidification categories for the lead acid battery system more than PHES. On the other hand, the production phase in PHES carries a higher contribution on the Eutrophication and Human Toxicity impact categories. The economic study in this thesis was checked by using the present worth analysis. Based on the technical component’s cost and life span for the two system, the feasibility study result shows that the PHES system is more fiscal than lead acid battery storage. The present worth for PHES was estimated at 651765 $ with the same life time of batteries and the same energy storage quantity. | en_US |
