DOE Picked 19 Projects for $45.7M in Critical Minerals Work. Two Pilot-Scale Plants Get Most of the Capital — the Other 17 Awards Set the R&D Bench for the Next Phase.

The Department of Energy's Office of Critical Minerals and Energy Innovation (CMEI) announced $45.7 million in selections across 19 projects on May 19, 2026 under FOA 3105, the Critical Material Innovation, Efficiency, and Alternatives funding opportunity. The announcement is not large by federal standards — $45.7 million is small money against the $1 billion in forthcoming DOE critical minerals funding the Department flagged in 2025, and small against the $134 million rare-earth recovery NOFO that closed for full applications in January. The announcement matters because the selection list reveals where the Department thinks the supply chain bottlenecks actually are, which technologies are now considered mature enough to move from research to pilot, and which institutions are positioned to absorb the next wave of capital.

The U.S. Geological Survey numbers that DOE cites in the announcement are the policy context. More than 95 percent of U.S. rare-earth element supply comes from foreign sources, over 50 percent of most critical minerals come from foreign sources, and at least 14 critical minerals are sourced exclusively from foreign sources. That dependency is concentrated in jurisdictions — primarily China for rare earths, the Democratic Republic of Congo for cobalt, China and Indonesia for nickel, and China for the overwhelming majority of graphite and manganese — that present a combination of geopolitical risk, environmental and labor concerns, and concentrated processing capacity that no single private actor can disrupt without sustained federal support. The Trump Administration has now bracketed this dependency as a national security priority, and the FOA 3105 selections sit inside an executive-branch strategy to reshore both extraction and processing within five to seven years.

The Two Pilot-Scale Selections Are the Real Story

Seventeen of the 19 selections are technology development projects — early- to mid-TRL research, university and national-lab work, modeling and characterization studies, and process development at bench or laboratory scale. The other two selections are pilot-scale processing facilities, and they receive the majority of the FOA 3105 capital.

USA Rare Earth was selected to build a continuous ion exchange rare-earth separation plant in Stillwater, Oklahoma. Rare-earth separation is the chokepoint in the global supply chain — even when domestic mining capacity exists, the separation step that breaks the rare-earth-bearing ore concentrate into the 17 individual rare-earth oxides has been almost entirely Chinese for two decades. Continuous ion exchange is an alternative to the conventional solvent extraction process that dominates Chinese rare-earth processing. The technology has been demonstrated at bench scale by several U.S. researchers; what FOA 3105 funds is the scale-up from bench to a continuous pilot plant capable of producing separated oxides in quantities that defense and electronics customers can actually qualify against. If the Stillwater plant produces the magnetic-grade neodymium, praseodymium, dysprosium, and terbium oxides that downstream magnet manufacturers need, USA Rare Earth has the most direct path to commercial production of any U.S. rare-earth separation venture.

Big Blue Technologies was selected to scale a magnesium metal production process from pilot to commercial in Cheyenne, Wyoming. Magnesium is a lower-profile critical mineral but a structural one — magnesium alloys are required for lightweighting in aerospace and automotive applications, magnesium die-casting is essential for electric-vehicle structural components, and China currently produces more than 85 percent of global primary magnesium. Big Blue's process uses ore and aluminum scrap as primary feedstocks to produce magnesium metal and calcium aluminate slag, with the slag itself a marketable byproduct that supports the unit economics. The modular smelter approach the company is pursuing also addresses a structural problem with conventional magnesium production: the dominant Pidgeon process used in China is highly energy-intensive and carbon-emitting, which makes it difficult to replicate in jurisdictions with environmental compliance costs. A modular electrolytic or thermal process that can be sited near scrap streams and inexpensive electricity changes the economics.

The pilot-scale selections share a structural feature that signals where CMEI wants its dollars to go. Both projects are scaling technologies that have already been demonstrated at smaller scale by their teams, both produce outputs that have identified downstream customers (rare-earth-magnet manufacturers in the USA Rare Earth case, aerospace and EV manufacturers for Big Blue), and both address materials where Chinese processing dominance is the binding supply chain constraint. The 17 R&D selections fill in the rest of the periodic table — lithium, cobalt, nickel, graphite, silicon, manganese — at earlier TRL levels, building the bench science that the next generation of pilot-scale solicitations will draw from.

The Geography and Institutional Mix Signal the Bench

The institutional list across all 19 selections is informative for researchers and small businesses thinking about where to position for the next solicitation cycle. The university awardees include Southwest Research Institute (San Antonio, TX), Princeton University, Columbia University, Ohio University, the University of North Dakota, Michigan Technological University, the University of Idaho, Texas A&M, and Vanderbilt. The national laboratory awardees include Battelle Memorial Institute (managing Pacific Northwest National Laboratory), the National Laboratory of the Rockies (Golden, CO), Idaho National Laboratory (with two selections), Argonne National Laboratory, Savannah River National Laboratory, Ames National Laboratory, and Lawrence Livermore National Laboratory.

Several of those institutions have been building critical-minerals research portfolios for years — Ames National Laboratory's Critical Materials Innovation Hub has been the dominant federal research center on rare earths since 2013, Idaho National Laboratory operates the largest U.S. nuclear materials processing capability and has expanded that infrastructure into critical-minerals work, and Michigan Tech's program in mining engineering and minerals processing has produced both the academic research base and the industry workforce that domestic processing scale-up requires. The geographic distribution is also deliberate. The selections concentrate in states with active mining, processing, or recycling industries (Idaho, North Dakota, Oklahoma, Wyoming) and in states with concentrated battery materials or magnet manufacturing capacity (Michigan, Ohio, Tennessee). The pattern is consistent with the DOE Rare Earth Elements Demonstration Facility strategy of building integrated extraction-to-product supply chains in geographic clusters rather than supporting individual node investments that would still depend on offshore processing.

For researchers and small businesses not currently on the FOA 3105 list, the institutional pattern is the more actionable signal than the dollar amounts. CMEI is funding teams that have either prior DOE critical-materials engagement, demonstrated processing or characterization capabilities in the specific materials they propose to work on, and credible pathways to downstream customer engagement. Teams that lack one of those three should not be planning to apply directly to the next FOA in the series — they should be planning to partner with one of the awarded institutions, or to position for the workforce, supply-chain, and demonstration-facility solicitations that are likely to follow as the technology development phase produces transition-ready candidates.

How FOA 3105 Fits in the Broader CMEI Strategy

CMEI is a relatively new DOE office in administrative terms — it consolidates critical-minerals work that had been distributed across the Office of Energy Efficiency and Renewable Energy, the Office of Fossil Energy and Carbon Management, and the Office of Manufacturing and Energy Supply Chains. The consolidation is meaningful because critical-minerals research had previously been fragmented across offices with different mission priorities, different program officer relationships, and different review processes. CMEI now sits as the single intake point for critical-minerals R&D, processing, and supply chain projects that are not part of the Energy Department's $1 billion in critical minerals funding opportunities more broadly.

The $45.7 million for FOA 3105 is the early-stage research and pilot-scale layer of CMEI's portfolio. The $134 million Rare Earth Elements Demonstration Facility solicitation that closed in January 2026 is the demonstration-scale layer, focused on commercial-viability demonstrations of recovering and refining rare earths from unconventional sources — mine tailings, electronic waste, coal byproducts. The Critical Minerals and Materials Accelerator provides another $69 million for supply-chain integration projects spanning lithium and rare earths. A separate $500 million critical-minerals battery supply chain initiative addresses the EV battery materials side specifically. The aggregate CMEI portfolio is therefore approaching $750 million across the full TRL spectrum, with FOA 3105 functioning as the funnel that identifies which technologies and teams are positioned for the larger demonstration and commercial-scale awards.

For small businesses outside the current FOA 3105 list, the strategic question is not whether to apply to the next round of FOA 3105 — by the time the next FOA 3105 cycle opens, CMEI will have additional information from the current cohort's first-year deliverables, and the topic structure will likely shift. The strategic question is which CMEI solicitation across the broader portfolio best matches the company's current technology readiness, customer engagement, and processing or characterization capability.

What Researchers and Small Businesses Should Do Now

Three concrete actions follow from the FOA 3105 announcement. First, the awarded teams will publish kickoff materials, milestone plans, and (eventually) interim results that map the actual technical pathways being pursued at each lab and university. Researchers planning to apply to the next CMEI solicitation should be reading those interim results before defining their proposed technical approach. Second, the pilot-scale selections (USA Rare Earth, Big Blue Technologies) will create demand for specialized equipment, qualified analytical services, and downstream customer qualification work that creates partnership and subcontract opportunities for companies that do not directly compete for the pilot-scale capital. Third, the broader CMEI portfolio includes solicitations that fund workforce development, supply-chain integration, and demonstration-scale follow-on work — these are different funding instruments with different review criteria, and the highest-leverage move for a researcher or small business currently outside the funded cohort is to identify which specific CMEI instrument matches their capability rather than treating CMEI as a single funding source.

The structural takeaway is that domestic critical-minerals supply chain reshoring is now a sustained, multi-instrument, multi-billion-dollar federal commitment that is not contingent on any single administration's continued support — the bipartisan consensus on China supply-chain risk is durable enough that future administrations will continue to fund this work even if the specific instrument design changes. For grantseekers, this is one of the most attractive areas in the federal R&D portfolio because the funding signal is consistent, the technology readiness pathway from research to pilot to demonstration is now visibly funded at each layer, and the downstream customer base (defense, automotive, electronics, energy storage) has explicit policy and procurement support for buying domestic.

Tools like Granted can map a research team's capabilities against the specific CMEI instruments now active, surface the bench-to-pilot transition criteria that FOA 3105 awardees met, and flag the matching downstream customer programs that make a critical-minerals processing project commercially defensible before the proposal goes in.
