Singapore is located at the equator, with abundant supply of solar radiation, relatively high ambient temperature and relative humidity throughout the year. The meteorological conditions of Singapore are favourable for efficient operation of solar energy based systems. Solar assisted heat pump systems are built on the roof-top of National University of Singapore’s Faculty of Engineering. The ob...

Solar Desalination In article number 2300189, Lin Li and co-workers present a Janus ion-selective hydrogel interfacial evaporator, which enables ion-electromigration salt removal. The from-scratch salt-removal route breaks the limitations of conventional water-convection enhanced routes, significantly lowers heat loss, achieving record-high evaporation rate holding great promise for future sola...

In this paper, the experimental design and computer simulation model of a multi-effect humidification/dehumidification (MEH) solar desalination system has been presented. The pilot plant on MEH was designed, fabricated and tested at the Center for Energy Studies, Indian Institute of Technology Delhi, India. The heat collection part has been designed to provide continuously the hot water to the ...

Membrane distillation (MD), which can utilize low-grade thermal energy, has been extensively studied for desalination. By incorporating solar thermal energy, the solar membrane distillation desalination system (SMDDS) is a potential technology for resolving energy and water resource problems. Small-scale SMDDS (s-SMDDS) is an attractive and viable option for the production of fresh water for sm...

This review provides a global overview of microporous silica based membranes for desalination via pervaporation with a focus on membrane synthesis and processing, transport mechanisms and current state of the art membrane performance. Most importantly, the recent development and novel concepts for improving the hydro-stability and separating performance of silica membranes for desalination are ...

Power systems for South and Central America based on 100% renewable energy (RE) in the year 2030 were calculated for the first time using an hourly resolved energy model. The region was subdivided into 15 sub-regions. Four different scenarios were considered: three according to different high voltage direct current (HVDC) transmission grid development levels (region, country, area-wide) and one...

Desalination of brackish water by using reverse osmosis (RO) system powered by solar PV has been till now not tried and examined in Palestine. This paper proposes the rural village Al Maleh for erection and testing of the first PV-powered RO system. Al Maleh is highly qualified for testing of such systems since it has a lot of mineral hot water springs of a salinity of about 3400 ppm. Based on ...
