Viability of Harvesting Salinity Gradient (Blue) Energy by Nanopore-Based Osmotic Power Generation Article

Zhangxin Wang, Li Wang, Menachem Elimelech

Engineering 2022, Volume 9, Issue 2,   Pages 51-60 doi: 10.1016/j.eng.2021.02.016

Abstract: development of novel materials with ion-selective nanochannels has introduced a new technology for harvesting salinitygradient (blue) energy, namely nanopore power generators (NPG).For module-scale NPG operation, we estimate both the power density and specific extractable energy (i.e., extractable energy normalized by the total volume of the working solutions), and elucidate the impactOverall, NPG systems produce very low net specific extractable energy (< 0.025 kW·h·

Effect of seawater salinity on the synthesis of zeolite from coal fly ash

Yanqing YU, Xiaoliang LI, Xiaolan ZOU, Xiaobin ZHU

Frontiers of Environmental Science & Engineering 2014, Volume 8, Issue 1,   Pages 54-61 doi: 10.1007/s11783-013-0493-4

Abstract: Seawater salinity was varied from 32 to 88 for zeolite crystallization during the hydrothermal processThe results show that seawater salinity plays an important role in zeolite synthesis with CFA duringThe products were a mixture of NaX zeolite and hydroxysodalite; seawater salinity more strongly affectedThe yield of CFA transformed into zeolite gradually rose with the increase in salinity, reaching a transformationrate of 48%–62% as the salinity increased from 32 to 88, respectively.
