The rising in the world’s population leads automatically to the rising in water demand. As a consequence the lack of drinking water increases Currently, approximately 1.2 billion people globally (one-sixth of the world’s population) do not have access to adequate clean water. Since a large part of the world’s population is concentrated in coastal areas, the desalination of seawater seems to be a promising solution, especially in our Arab world. An innovative stand-alone solar desalination system could be used to produce drinking water from seawater or any brackish water sources. The great advantage of such a system is that it combines efficient desalination technology, reverse osmosis, with a renewable energy source. The main goal is to improve the technical feasibility of such systems, There are many advantages of this coupling with RE resources ; first of all we separate the drinking water from the electricity grid and its faults, save burning the fossil fuel and its emissions, and provide fresh water to remote communities that do not have sufficient traditional energy sources. But as we see in this study we don’t have economic benefit; because these projects depend on the electricity cost in each country and the location and its solar specifications. We designed and implemented a small laboratorial model for PV-RO (Photo-Voltaic Powered Reverse Osmosis) to recognize the performance for seawater and brackish water, we faced some problems such as embargo on Syria; so have done project using affordable local potentialities, but we craved to keep the principle of operation, so we make it for the tap water which close to brackish.

Poly(vinyl alcohol)(PVA)/cellulose acetate(CA) composite membranes were preparedfor metal ions removal from water. The top layer was modified by polyethylene glycol and glycerin,then irradiated with 32[J/cm2] photo dose to improve adequate selecti vity for metal ions separation. The flux of water increased with increasingoperating pressure, and the maximum value of flux was 200[L/m2.h] at 4[bar] for the membrane(PVA68/PEG17/G15), but this membrane tear after applying pressure above 4[bar], while composite and CA membranes served for long time at pressures higher than (4[bar]). The rejection of ions decreased as the feed water pressure increased. The maximum percent retention of ions was found to be 97% for Pb+2, 96% for Cu+2, and 95% for Co+2at pressure of 2[bar] in composite membrane.
In this paper, we have suggested the STATCOM (STATic synchronous COMpensator) to connect PV-solar (or wind) frame to the power system for the Hassia industrial city which we chose as a case study. This frame will provide the city with the required power, improve the power quality and inject the redundant to the power system.
This study evaluates the energetic and environmental performances of a group of renewable energy technologies widely used in the residential sector, by applying them to a typical housing unit that resembles to some extent our local housing units. Then comparing those technologies with the conventional ones. The renewable energy technologies used in this study are: thermosiphon domestic solar water heater with evacuated tube collector, PV system, geothermal heat pump (GSHP), in addition to four hybrid systems that include: the solar water heater with three types of backup systems (diesel, electricity and natural gas) and a hybrid system that combines between the geothermal heat pump and a PV system to operate it.
Fresh water shortage problem is the most important difficulty that counters agricultural and industrial improvement strategies on both Arabic and international levels, where Arabian region extends along vast arid and semi- arid areas, and mostly la cks for fresh water resources. Therefore, desalination choice has become an inevitable option to compesate deficiency of water, especially with the long Arabian costal line, where desalinated seawater is considered renewable fresh water resource. However, desalination mechanism requires water pretreatment procedures in order to reduce total hardness and pH values, to prevent salts precipitations which hinder thermal and membrane techniques.
The integration of various renewable energy sources as well as the liberalization of electricity markets are established facts in modern electrical power systems. The increased share of renewable sources within power systems intensifies the supply variability and intermittency. Therefore, energy storage is deemed as one of the solutions for stabilizing the supply of electricity to maintain generation-demand balance and to guarantee uninterrupted supply of energy to users. In the context of sustainable development and energy resources depletion, the question of the growth of renewable energy electricity production is highly linked to the ability to propose new and adapted energy storage solutions. Recent advancements in hydrogen technologies and renewable energy applications show promise for economical near to conversion to a hydrogen-based economy. As the use of hydrogen for the electric utility and transportation sectors. This paper briefly discusses provides a historical perspective for hydrogen production and the role of hydrogen as an energy carrier, discusses hydrogen economy, the process of electrolysis for hydrogen production (especially from solar and wind technologies). A comprehensive techno/socio/economic study of long term hydrogen based storage systems in electrical networks is addressed. the excess produced hydrogen during high generation periods or low demand can be sold either directly to the grid owners or as filled hydrogen bottles. The affordable use of Hydrogen-based technologies for long term electricity storage is verified. The results indicate that ample resources exist to produce Hydrogen from wind and solar power. However, hydrogen prices are highly dependent on electricity prices.
