Solar and wind are playing a greater role in power generation, leading to hundreds of gigawatts worth of new renewable energy generation. However, without effective energy storage techniques, natural gas and coal are needed for times when weather conditions aren’t favourable. Large-scale storage is becoming instrumental if society is to shift away from a world dependent on fossil fuel, and will define the next decade.
This report discusses the rising market demand for lithium and the land reserves of lithium is going to be depleted by the end of 2080. That’s why there is a need to find some alternative. As rejected brine seawater contains a lot amount of lithium, there is a need to extract that lithium from the seawater. The process description and working of the electrochemical cell are explained in this report. A comparison of different techniques to extract lithium is also provided and the best possible techniques so far are discussed which was practically performed by the King Abdullah University of Science and Technology (KAUST) and some results of this experiment have also been shared.
