DE-FOA-0000472: Rare Earth Alternatives in Critical Technologies for Energy (REACT)

Rare earths are naturally-occurring minerals with unique magnetic properties that are used in many emerging energy technologies. As demand for these technologies continues to increase, rare earths are rapidly becoming more expensive due to limited global supply – prices of many have increased 300–700% in the past year. Rising rare earth prices have already escalated costs for some energy technologies and may jeopardize the widespread adoption of many critical energy solutions by U.S. manufacturers. ARPA-E seeks to fund early-stage technology alternatives that reduce or eliminate the dependence on rare earth materials by developing substitutes in two key areas: electric vehicle motors and wind generators.
