Thermal and salinity gradient systems

2019
The book chapter presents thermal and salinity gradient energy (SGE) systems. First, a description of both energy resources and the determination of energy potential is given. Then, power plants that convert the thermal gradient potential as well as the salinity gradient are discussed.

Reverse Electrodialyis Salinity Gradient Power Experiment

Volume 1: Combined Energy Cycles, CHP, CCHP, and Smart Grids; Concentrating Solar Power, Solar Thermochemistry and Thermal Energy Storage; Geothermal, Ocean, and Emerging Energy Technologies; Hydrogen Energy Technologies; Low/Zero Emission Power Plants and Carbon Sequestration; Photovoltaics; Wind Energy Systems and Technologies, 2014
Today’s rate of fossil fuel consumption rapidly depletes fuel reserves and leads to a number of adverse environmental effects. Although the scope of these effects has yet to be fully realized, it is clear that the development of alternative energy sources is very important.

Multi-stage reverse electrodialysis: Strategies to harvest salinity gradient energy

Energy Conversion and Management, 2019
Reverse electrodialysis heat engine (REDHE) is an effective technology to harvest salinity gradient energy (SGE) driven by low grade heat. In order to improve the energy conversion efficiency of it, one practical way is to enhance the capturing SGE ...

Experimental studies on the effect of using phase change material in a salinity-gradient solar pond under a solar simulator

Solar Energy, 2019
Thermal energy storage (TES) is a technology that stocks thermal energy by heating a storage medium so that the stored energy can be used at a later time for heating applications and power generation. This paper is focused on an experimental study of the

Recent development in salinity gradient power

Oceans 2003. Celebrating the Past ... Teaming Toward the Future (IEEE Cat. No.03CH37492), 2003
An often-overlooked source of marine renewable energy is the energy available from salinity gradients. The potential resource for the osmotic pairing of fresh water and seawater is estimated at 2.6 TW. Several concepts have been proposed. Obviously, any scheme to desalinate seawater can be operated in reverse.

Langmuir turbulence in horizontal salinity gradient

Ocean Modelling, 2018
Abstract Langmuir circulation (LC) is believed to be one of the leading causes of turbulent mixing in the upper ocean. Large eddy simulation (LES) models that solve the Craik–Leibovich equations are used to study LC in the upper ocean, yielding new insights that could not be obtained from field observations or turbulent closure models alone.

Salinity Gradient Energy at River Mouths

Environmental Science & Technology Letters, 2014
River mouths are potentially abundant locations for the exploitation of the clean and renewable salinity gradient energy (SGE) as here perpetually fresh water mixes with saline seawater. However, the practical yield of SGE depends on the spatiotemporal variability of the salinity structure.

Salinity-gradient vapor-pressure power conversion

Energy, 1982
Abstract 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.
