||In 2013, the Advanced Research Projects Agency – Energy (ARPA-E) launched an initiative, the METALS Program, to reduce energy, emissions, and cost for primary production of light metals. The projects that comprise the METALS (Modern Electro/Thermochemical Advances in Light Metal Systems) Program are focused on innovative approaches to extract aluminum, magnesium, or titanium directly from ore precursors. The objectives of the METALS program are to enable these transformative production routes by meeting programmatic goals on energy, emissions, and cost. Developing advanced extraction technologies for the efficient and economical production of light metals will further enable widespread use of light metals in ground vehicles and aircraft, substantially reducing fuel consumption and CO2 emissions from the transportation sector. This symposium invites any submissions that align with the goals to substantially reduce energy, cost, and emissions associated with light metal extraction from ores.
