US DOE backs seven critical-minerals R&D programmes as US push to break China’s grip deepens
The US Department of Energy's Office of Critical Minerals and Energy Innovation has proposed $10 million in awards for seven projects focused on early-stage recovery and refining technologies for heavy rare earths, gallium and copper — materials whose supply chains are concentrated in China to a degree that US industrial and national security planners regard as structurally untenable.
The projects, led by the DOE's Critical Materials Innovation Hub at Ames Laboratory, span a range of novel extraction approaches:
Case Western Reserve University is developing chloride-based molten-salt electrolysis for heavy rare-earth metal production; the Colorado School of Mines and the University of Arizona are advancing new hydrometallurgical and nanobubble-enhanced processes; and FAST Metals is targeting the extraction of gallium and mixed rare-earth oxides from industrial byproduct residue streams — exploiting waste flows that currently carry no extractive value.
The $10m figure is deliberately modest: these are seed-stage R&D investments, not commercial deployments. Their significance lies not in their size but in the policy layer they complete. In December 2025, DOE made US$134m available to demonstrate the commercial viability of recovering rare earths from mine tailings and e-waste. In August 2026, it announced $500m in funding for seven projects covering battery materials processing, recycling, and manufacturing.
On August 10, the Department of Defense's Office of Strategic Capital signed conditional loan commitments exceeding $2 billion — including US$1.4bn to battery cell manufacturer Sila Technologies, $400m to Australia's Sunrise Energy Metals and $150m to rare.
Taken together, the US government has committed over US$2.6bn to critical minerals supply chain development in the past nine months alone, spanning the full value chain from upstream R&D through demonstration-scale processing to commercial manufacturing and financing.
The US$10m R&D tranche is the basic science layer of that architecture — the point where new extraction chemistries are validated before being scaled through the demonstration and manufacturing programmes above it.
The strategic logic is directed at China. China produces approximately 80% of the global gallium supply, a by-product of bauxite-alumina refining. It imposed export licensing controls on gallium and germanium in August 2023 and tightened them further in December 2024.
Gallium is essential for high-voltage semiconductors, light-emitting diodes, high-strength permanent magnets, space solar cells and integrated circuits — the same components that underpin renewable energy hardware, EV motors, defence electronics and AI computing infrastructure.
Heavy rare earths — specifically dysprosium and terbium — are similarly concentrated in Chinese separation and processing, and are critical for the high-strength NdFeB permanent magnets used in wind turbine direct-drive generators and EV traction motors.
The DOE's investments in alternative production routes — particularly gallium recovery from waste streams that operate at scale in alumina refineries — are aimed at creating supply chain optionality that does not depend on goodwill from Chinese export licences.
India's stake in this campaign is direct and underappreciated. The Quad Critical Minerals Initiative Framework, announced at the Quad Foreign Ministers' Meeting in New Delhi on 26 May 2026, commits India, Australia, Japan and the United States to coordinated diversification of the supply chain for exactly these materials. India is therefore not merely an observer of the US critical minerals push — it is a declared partner in its strategic logic.
The India-specific exposure is substantial: India's National Semiconductor Mission (₹76,000 crore; US$ 8 bn) will require gallium for compound semiconductor fabrication at a scale that cannot be safely sourced entirely from China.
India's National Critical Mineral Mission (₹16,300 crore, US$ 1.7 bn approved March 2025) covers overlapping materials and has established KABIL to acquire overseas mineral assets. India's significant rare earth reserves — estimated at 6.9 million tonnes through IREL, representing around 6% of global resources — remain largely unprocessed domestically due to the absence of competitive refining technology.
If the US DOE's alternative processing chemistries — particularly waste-stream gallium recovery methods using ion exchange and electrochemical separation — prove commercially viable, they could be transferred to India's refineries, including those operated by Nalco, Hindalco and Vedanta, whose bauxite-alumina operations generate the exact waste streams the Indium Corporation and Oak Ridge projects are designed to exploit.
