Project Innovation + Advantages: PNNL is developing a radically new process to produce magnesium from seawater. Today's methods are energy intensive and expensive because the magnesium concentration in seawater is so low that significant energy is needed to evaporate off water and precipitate magnesium chloride salt.ritical Need: Primary production of lightweight metals such as magnesium is an energy-intensive and expensive process that results in significant carbon dioxide (CO2) and other emissions.
