Harnessing the energy created from salinity gradients—for example, when freshwater meets the sea—could provide a renewable source of power able to mitigate climate change impacts, reduce reliance on fossil fuels and improve processes within the desalination industry, according to new research from Griffith University (Queensland, Australia).

n a paper published in the journal Renewable and Sustainable Energy Reviews, Dr Fernanda Helfer and Professor Charles Lemckert, from Griffith’s School of Engineering, review investigations into the potential of salinity gradient energy, which is released when waters with different salinities mix.
