“…Several cost analysis studies have been conducted for seawater desalination using RO and other technologies [348][349][350][351][352]. Unit costs between $0.06/m total cost as compared to the power cost for seawater RO (up to 44%) [354].…”

Membrane distillation is a process that utilizes differences in vapor pressure to permeate water through a macro-porous membrane and reject other non-volatile constituents present in the influent water. This review considers the fundamental heat and mass transfer processes in membrane distillation, recent advances in membrane technology, module configurations, and the applications and economics of membrane distillation, and identifies areas that may lead to technological improvements in membrane distillation as well as the application characteristics required for commercial deployment.

“…The RO investment, maintenance, and energy costs have been evaluated using a general production cost breakdown from the literature (Akgul et al 2008): 0.24 $/ m 3 for the investment cost, 0.27 $/ m 3 for the maintenance cost, 0.19 $/m 3 for the energy cost. Maintenance takes into account all the aspects of RO operations like the substitution of exhausted membranes and the fast decay of components operating with salt water.…”

“…The process of pumping feeding water to the pressure required at the inlet of the vessel, ranging between 65 and 80 bar, is very energy-consuming, representing 70 % of the operating cost, and 33 % of the total production cost (Akgul et al 2008). In the presence of a daily variability of electricity prices in Southern Italy, Ghobeity and Mitsos (2010) have demonstrated that the saving potentials of both electricity and plant costs are significant (10.6 and 5.0 %, respectively) by allowing the system to remain idle during high electricity cost hours.…”

“…This cost has been reduced further in the last ten years to 0.4 $/m 3 due to the plant having a larger capacity than 5000 m 3 /d (Akgul et al 2008;Ziolkowska 2015;Ziolkowska and Ziolkowski 2016). The main variables affecting the water cost are the concentration of the feeding water, the membrane recovery ratio, the required quality of the permeate effluent, and the efficiency of the high pressure feed pumps and booster pumps.…”

“…In the last twenty years, seawater or brackish water desalination has become a fully developed process. Reverse osmosis has been reported as a diffuse drinking water solution in coastal areas of Turkey (Akgul et al 2008). Large seawater reverse osmosis plants are also present in Israel and Cyprus (Wilf 2005).…”

Water scarcity and the poor quality of water resources are leading to a wider diffusion of desalination plants using the Reverse Osmosis (RO) process. Unfortunately, the cost of a cubic meter of fresh water produced by an RO plants is still high and many efforts are in progress to increase the efficiency of the membranes used in osmotic plants and to limit the energy required by the process. A further reduction of the energy cost could be obtained by an optimal operation of the desalination plant so reducing the hourly energy cost, or by coupling the RO plant with an energy production plant based on direct osmosis (Pressure Retarded Osmosis PRO). The economic viability of the desalination process has been analyzed until now without accounting for the integration of the RO plant with the existing water network. This analysis is developed in the present paper with reference to a hypothetical change of water supply in a real network, where a desalination plant is used to satisfy the fresh water demand. Several scenarios will be analyzed to assess the minimum cost of fresh water production and water supply to the network, including the use of energy recovery systems, such as an integrated use of RO and PRO processes, or the regulation of pressure at the network intake by a micro hydro power plant.

Considerable research is taking place globally concerning the energy consumption in residential buildings. The effort is aimed toward the creation of zero energy buildings or even positive energy ones. In order to accomplish this, energy production is needed at the building level. Electrical energy, thermal energy for space heating and cooling, and domestic hot water production are common needs globally, whereas water pumping, water desalination, and onsite fuel production are also of rising interest. The polygeneration microgrid topology aims at unifying all the energy systems in a building and through advanced energy management approaches to optimize the energy flows in the building managing to provide optimum indoor comfort, meeting of all the energy needs of the residents and minimizing the environmental impact of the building. This article presents this topology in detail and also proposes a methodology for the design and sizing of such systems.
