Critical Materials Institute

What is the Energy Innovation Hub for Critical Materials?
Created by the U.S. Department of Energy, the Energy Innovation Hub will operate under the name, the Critical Materials Institute (CMI). The CMI will be led by the DOE’s Ames Laboratory and bring together the expertise of four DOE national laboratories, seven universities and seven industry partners to eliminate materials criticality as an impediment to the commercialization of clean energy technologies for today and tomorrow.

What are “critical” and “near critical” materials?
Certain substances provide essential capabilities, such as light emission, magnetism or others, and when the supply of one of these substances is at risk, it becomes a “critical” material. The Department of Energy has identified five rare-earth materials " neodymium, europium, terbium, dysprosium and yttrium"as critical materials, materials essential for America’s transition to clean-energy technologies. The DOE has identified two additional elements, lithium and tellurium, as “near-critical” materials. These non-rare-earth materials play an indispensable role in emerging energy storage and battery technologies, such as hybrid and electric vehicles, wind turbines, and photovoltaic thin films.
