Low-Grade Waste Heat Utilization

In many heat-intensive industrial processes, waste heat is produced at too low of a temperature to be useful for other industrial processes and needs to be discarded. Sometimes it is possible to distribute it as useful heat in residential buildings (i.e. Combined Heat and Power systems, CHP), but it is not always logistically or economically feasible. Therefore, efforts have been made to generate electricity from the waste heat using unconventional methods.

It is possible to utilize low-grade waste heat to generate electricity using a RED system. A regenerator is used to replenish a salinity gradient using the waste heat (e.g. distilling brackish water into dilute and concentrated solutions). The two regenerated feed solutions are then used in a RED stack to generate electricity. This type of system could be installed in industrial or residential zones where there is waste heat available.
