Sustainable Energy from Salinity Gradients

Salinity gradient energy, also known as blue energy and osmotic energy, is the energy
obtainable from the difference in salt concentration between two feed solutions, typically
sea water and river water. It is a large-scale renewable resource that can be harvested and
converted to electricity. Efficient extraction of this energy is not straightforward, however.
Sustainable Energy from Salinity Gradients provides a comprehensive review of resources,
technologies and applications in this area of fast-growing interest.
Key technologies covered include pressure retarded osmosis, reverse electrodialysis and
accumulator mixing. Environmental and economic aspects are also considered, together with
the possible synergies between desalination and salinity gradient energy technologies.
Sustainable Energy from Salinity Gradients is an essential text for R&D professionals in the
energy & water industry interested in salinity gradient power and researchers in academia
from post-graduate level upwards.
