Abstract: Renewable clean energies such as wind, solar power usually suffer severe problems such as being intermittent, unstable, etc. Thus, it is necessary to explore better sustainable renewable energy to meet the ever-growing global energy demand.A novel way of electrical power generation by Forward Osmosis (FO) driven electrokinetic (EK) phenomenon, termed as salinity water battery, was studied and demonstrated in this project. This project’s objective is to improve the output power of the water battery through surface additive treatment on the porous medium, which forms the core part of the water battery. Two different types of surfactants, namely DMAPS and SDS, were utilised to treat the surfaces of the porous media with varying porosity and thickness. Parametric studies were carried out to investigate the effect of the surfactants on the performance of the water battery in generating power through the porous medium. The parameters include material of porous media, porosity and tortuosity of porous media, pore size of porous media, concentration of additive used and surface charge density.
