Integrated energy systems utilizing renewable sources are sustainable and environmentally substitutes for conventional fossil-fired energy systems. A new multigeneration plant with two inputs, such as biomass and solar energy, and four useful outputs, such as cooling, heating, power, and distilled water, is presented and investigated in this paper. The proposed system includes evacuated tub...

This work focuses on the design of a supervisory predictive control system for the optimal management and operation of a stand-alone wind-solar energy generation system which provides power to a reverse-osmosis (RO) water desalination system. We design the supervisory control system via model predictive control which coordinates the wind and solar subsystems as well as a battery bank to best sa...

This paper demonstrates the preliminary experiments for two stage water desalination by humidification-dehumidification HDH process. An experimental set-up consists of two stages of closed air humidification dehumidification units. In this design, the saline water was heated by evacuated tube solar water heater integrated with electrically heated tank. A series of tests were performed in outdoo...

World-wide water scarcity, especially in the developing world, indicates a pressing need to develop inexpensive, decentralized small-scale desalination technologies which use renewable resources of energy. This paper provides a comprehensive review of the stateof-the-art in one of the most promising of these technologies, solar-driven humidification-dehumidification (HDH) desalination. Previous...

The Gulf countries are located in the arid and semi-arid regions where rainfall is scanty and evaporation rates are high. Surface water is limited and there are no perennial streams. The increase in population and socio-economic development has led to an imbalance between supply and demand. These countries depend mainly on desalination to meet the growing water needs. This paper reviews the his...

An experimental desalination system coupling a vacuum membrane distillation (VMD) unit and a vacuum tube solar heat collection (SHC) unit was developed and tested. The parametric sensitivity of the VMD unit performance was investigated first using an electric heater as the heat source, and then the whole system was examined using solar heat. It was revealed that hot feed temperatures higher tha...

A scheme is proposed to desalinate sea water using solar energy for the Thar Desert of India. The scheme has been using solar energy for the Thar Desert of India. The scheme has been designed to produce about 5.25 x 10 m/yr (13860 MG/yr) of fresh water with 11.52 km (4.5 miles) of collector area. The solar collectors are rectangular concrete tubes, half buried in the ground, through which sea w...
