Sustainable water and energy in Gaza strip
Shortage of fresh water is a common problem in different areas of the world including the Middle East. Desalination of seawater and brackish water is the cheapest way to obtain fresh water in many regions. This research focuses on the situation in Gaza Strip where there is a severe shortage in the energy and water supply. The depletion of fresh water supplies and lack of wastewater treatments result in environmental problems. A solar-powered co-generation plant producing water and energy is proposed to be a suitable solution for Gaza Strip. Solar energy, using concentrating solar thermal power (CSP) technologies, is used to produce electricity by a steam cycle power plant. Then the steam is directed to a desalination plant where it is used to heat the seawater to obtain freshwater. The main objective of this research is to outline a solution for the water problems in Gaza Strip, which includes a co-generation (power and water) solar-powered plant. The research includes four specific objectives: (1) an environmental and economic comparison between solar and fossil fuel energies, (2) technical details for the co-generation plant, (3) cost and funding, (4) the benefits.
