Reverse electrodialysis (RED) as an emerging technology to transform salinity power

is deserving much attention due to its superior characters

i.e.

sustainability

high energy intensity and environment friendly. The new implementations and current progress of RED and its applications on renewable energy & environment protection were summarized from the viewpoint of elementary factors such as configurations

working mechanism and influencing parameters

by considering the key issues (virtual challenges confronting all the country)

i.e.

energy shortage and environmental pollution. The single RED operation and the integrations with other technologies were summarized and introduced specifically. The context has made a generalization and summarization of the sphygmology of previous published works in order to provide a reference to the works in progress.
