As quoted in the market news:
PNNL is leading a $2.7m, three-year project to develop a novel method that removes naturally occurring magnesium from seawater. The project was by DOE’s Advanced Research Projects Agency-Energy (ARPA-E).
‘Demand for lightweight metals such as magnesium is growing, but it’s expensive and energy-intensive to produce them,’ said the project’s lead researcher, PNNL Laboratory Fellow Pete McGrail. ‘We expect our method will be 50 per cent more energy efficient than the United States’ current magnesium production process. This will also decrease carbon emissions and the cost.’
