U.S. Department of Energy Awards $2 Million for Innovations to Source Domestic Lithium From Geothermal Brines
The U.S. Department of Energy (DOE) today announced the winners of its first-ever American-Made Geothermal Lithium Extraction Prize. Three teams will split a total of $2 million for prototyped innovations to directly extract lithium from the hot water used to produce geothermal energy, known as geothermal brines. Lithium is a crucial element in the clean energy supply chain, but the United States currently imports about 99% of its lithium supply. Work under the prize helps support access to cost-effective, domestic sources of this critical mineral for batteries for stationary storage and electric vehicles—crucial to meet the Biden-Harris Administration’s goals of 50% electric vehicle adoption by 2030 and a net-zero emissions economy by 2050. Advancing geothermal lithium extraction will also help ensure American leadership in the clean energy future and create U.S. jobs and a strong domestic supply chain.

Gaurav Singhal receives Innovation Award
Our graduate students are difference-makers. Gaurav Singhal is sheer proof. The MatSE graduate is the recipient of the Innovation Award for his efforts in solving semiconductor chip packaging problems.
This award comes with a cash reward and a medallion — all of which is made possible by the generosity of ’74 doctorate alumnus Durgam Chakrapani and his family, who helped establish the Durgam and Subha Chakrapani Family Trust. Each year, the trust awards one MatSE graduate student for an outstanding Ph.D. thesis characterized by innovation and potential for commercialization in the field of materials science and engineering.
“Gaurav has been actively leading two projects funded by industry and has five patents associated with his work. The ability to perform both fundamental materials science and translate that work into technologically relevant findings really made him stand out,” Evans said.
