“…In the remote regions of Canada, diesel engines are the main source of energy which are not considered sustainable. For example, in the remote regions of Quebec, the potential of the osmotic power was estimated to be in the range of 0.9 -10.5 TWh/year, which is sufficient to meet the energy demand in those remote regions [14]. However, there was a clear gap present in the literature regarding the potential of osmotic power in other major Canadian provinces such as Ontario.…”

“…The potential of the PRO system was investigated in many countries. For example, the potential PRO energy was estimated to be in the range of 0.9-10.5 TWh/year in the remote regions of Quebec, Canada [12]. There is no commercial membrane that is engineered or optimized for the PRO process.…”

Pressure retarded osmosis (PRO) is considered as one of the promising and new techniques to generate power. In this work, a numerical model was used to study the effect of the flow streams temperature on the performance of the PRO process and entropy generation. The variation of the feed solution and draw solution temperatures, pressure difference, concentration difference, and flow rates on the power density and entropy generation were discussed. The model results were validated with experimental measurements obtained from literature and showed a good agreement with the model predictions. It was found that the power density increases by about 130% when both feed solution and draw solution temperatures increase from 20 °C to 50 °C. The feed solution temperature has more impact on the power density than that of the draw solution. This is due to the direct effect of the feed solution temperature on the water permeability and diffusion coefficient. The effect of the feed solution temperature becomes significant at higher concentration differences. Whereas, at low concentrations, the power density slightly increases with the feed temperature. Furthermore, it is found that there is an optimum volumetric flow in the channels that maximizes the power density and minimizes the entropy generation when fixing other operating conditions.

“…On the other hand, this technology has outstanding benefits, such as having the lowest emission of greenhouse gases (GHGs) [5], it does not consume either water or salt in the process, and requires low flow to generate enough energy to supply remote populations [6]. It can also be used in hybrid applications, including its combination with other renewable energies, wastewater treatment plants [7,8], and drinking water systems [9].…”

Abstract. The energy potential of the osmotic pressure gradient of cyanide waters is evaluated using two membrane modules, horizontal and vertical, operated under dead-end flow. The membrane was characterized using Scanning Electron Microscopy (SEM) with Energy Dispersive X-ray Spectroscopy (EDS). The membrane is mainly composed of carbon, oxygen, and sulphur. The properties of the membrane were unchanged and had no pore clogging after exposure to the cyanide waters. Potentials of 1.78×10 -4 and 6.36×10 -5 Wm -2 were found for the horizontal and vertical modules, respectively, using the Van't Hoff equation. Likewise, the permeability coefficient of the membrane was higher in the vertical module. Although the energy potential is low under the studied conditions the vertical configuration has a greater potential due to the action of gravity and the homogenous contact of the fluid with the membrane.
