Influence of Nanopore Size on the Performance of Salinity Gradient Power
ECS Meeting Abstracts, 2016Retrieving energy based on a salt concentration difference between two liquid phases, such as sea water and fresh water, has emerged as one of the promising next-generation renewable energy techniques. Recent advances in nanotechnology and nanofabrication also make relevant applications attractive. According to the mechanisms involved, relevant results

Salinity‐Gradient Power Generation with Ionized Wood Membranes
Advanced Energy Materials, 2019AbstractReverse electrodialysis (RED) is known as an efficient way of converting the salinity gradient between river water and sea water into energy. However, the high cost and complex fabrication of the necessary ion exchange membranes greatly prohibit the development of the RED process. For the first time, an ionized wood membrane is demonstrated for

Salinity Gradient Power Experiment Using Reverse Electrodialysis
Volume 6A: Energy, 2014A relatively new form of alternative energy known as reverse electrodialysis (RED) appears to be one of the promising energy sources of the future. This technology harvests the energy stored in the salinity gradient between two different liquids, and converts it directly into electric power.

Reverse electrodialysis in bilayer nanochannels: salinity gradient-driven power generation
Physical Chemistry Chemical Physics, 2018To evaluate the possibility of nano-fluidic reverse electrodialysis (RED) for salinity gradient energy harvesting, we consider the behavior of ion transportation in a bilayer cylindrical nanochannel with different sized nanopores connecting two reservoirs at different NaCl concentrations.

Salinity-gradient vapor-pressure power conversion
Energy, 1982Abstract The interface between water bodies of different salinities represents a large unexploited source of energy. An energy conversion approach that does not require the use of membranes but uses the differences in vapor pressure between solutions is examined.

Development of a salinity gradient power: upwelling tests using FLIP
Oceans '04 MTS/IEEE Techno-Ocean '04 (IEEE Cat. No.04CH37600), 2005A series of upwelling experiments were conducted onboard the research platform FLIP in May 2004 off San Diego, California. The objective was to test the relationship between pipe length and seawater entrainment or exit velocity towards development of a salinity gradient power source.

Charge-doped electrodes for power production using the salinity gradient in CapMix
Desalination, 2020Abstract In this paper, we show the effects of various types of polyelectrolytes and functionalized particles on the properties of soft electrodes in the CapMix process. To build negatively charged electrodes, poly(acrylic acid), poly(methacrylic acid), mixture poly(acrylic acid) and poly(methacrylic acid) and poly (4-styrenesulfonic acid) sodium ...

Using Smart Nanochannels as a Power Switch in Salinity Gradient Batteries
ChemNanoMat, 2019AbstractAlthough biomimetic smart gating nanochannels have been explored extensively, research on practical applications of these systems is scarce. Here, we demonstrated an engineered track‐etched asymmetric porous polyethylene terephthalate (PET) membrane modified with redox‐active Cytochrome C (Cyt C), which served as a gatekeeper due to its redox ...

Sulfonated Sub-Nanochannels in a Robust MOF Membrane: Harvesting Salinity Gradient Power
ACS Applied Materials & Interfaces, 2019We developed a robust, crack-free ultrathin zeolite- imidazole framework (ZIF-8) membrane in-built with a sulfonate-ion-containing polymer (ZIFHep) via a vapor-assisted in situ conversion process. The sulfonated sub-nanochannels of the ZIFHep membrane afforded a rapid and selective transport of Li+ over counteranions and other alkali ions due to ...
