Seawater desalination plants have been built in Australia in response to increasing pressure on water supplies. The sustainability of these plants is challenged by their significantly high energy cost and concentrated brine output. By exploiting the high residual hydraulic energy contained in the concentrated brine and using it in a membrane-based hybrid system with renewable osmotic energy, this project aims to provide solutions for overcoming these challenges. Renewable osmotic energy will be generated from the salinity differences between concentrate and fresh seawater (or other water sources) by pressure retarded osmosis. This will be enabled by the development of highly efficient composite membranes using an electrospinning technique.

澳大利亚已经在澳大利亚建造了海水脱盐厂，以应对供水压力的增加。这些植物的可持续性受到其明显高的能源成本和集中盐水产量的挑战。通过利用浓盐水中包含的高残留液压能，并将其用于具有可再生渗透能量的膜的混合系统中，该项目旨在为克服这些挑战提供解决方案。可再生渗透能量将是由浓缩物与新鲜海水（或其他水源）之间的盐度差异产生的，压力阻碍了渗透。这将通过使用静电纺丝技术开发高效的复合膜来实现这一点。
