A novel off-grid thermoelectric-photovoltaic desalination system

Desalination of brackish water/sea water is a sustainable way to meet water demand in arid locations. A
number of humidification/dehumidification (HDH) devices based on conventional vapor compression
technology are currently available. However, these devices have a number of inherent problems such as
high noise levels, compressor vibration and excessive weight and size.
The overall objective of the project is to develop and demonstrate a novel off-grid desalination system
using thermoelectric technology combined with a photovoltaic system.
The combination of photovoltaic (PV) and thermoelectric (TE) technologies will not only overcome the
problems of a conventional desalination system, but it also brings many additional advantages such as being
off-grid, having less moving parts, easy to install, less maintenance, and on top being environmentally
friendly.

The outcome of the project will be:

1. High performance thermoelectric-solar desalination prototype to cheaply produce potable water with a targeted coefficient of performance (COP) of more than 1.5.
2. Demonstration of a future environmentally friendly energy technological concept with high commercial potential.

Overall, a PV-TE desalination system can take advantages of both technologies in terms of energy
efficiency and economy as well as environment. Therefore, a great market potential is expected.
