The $69 Million Nobody Is Talking About: DOE Quietly Opens the Critical Minerals Accelerator

Gallium. Germanium. Lithium. Rare earth elements. These materials underpin everything from fighter jet electronics to electric vehicle batteries to the semiconductor chips that run artificial intelligence workloads. The United States produces virtually none of them at commercial scale. China controls roughly 60 percent of global rare earth mining and 90 percent of processing. When Beijing restricted gallium and germanium exports in July 2023 — and tightened those controls again in December 2024 — American manufacturers discovered just how thin the supply margin had become.

The Department of Energy's answer is not a single moonshot. It is a methodical, phased program called the Critical Minerals and Materials Accelerator, and on April 7, 2026, DOE opened a $69 million funding opportunity that most of the grant-seeking world has overlooked. The applications are staggered across three deadlines — May 29, June 25, and July 23 — and the program sits within a broader pipeline of nearly $1 billion in critical minerals funding that DOE has been quietly assembling since mid-2025.

If your organization works in materials science, mining technology, lithium extraction, semiconductor materials, or rare earth recycling, this is one of the most significant federal funding opportunities of the year.

Three Topic Areas, Three Deadlines, One Strategy

The Accelerator NOFO is structured around three distinct topic areas, each with its own budget, award range, and submission deadline. This is not a single competition — it is three parallel competitions sharing a common framework.

Topic Area 1: Recycling and Recovery of Critical Materials ($24 million, deadline May 29). This track funds technologies that extract critical materials from industrial scrap, consumer waste, and mine tailings. DOE expects to make 10 to 14 awards of up to $2 million each. The underlying logic is straightforward: the United States already generates enormous volumes of e-waste, spent catalytic converters, coal ash, and industrial byproducts containing recoverable concentrations of rare earth elements, cobalt, nickel, and other critical materials. The problem is not feedstock — it is economically viable separation and refining at scale.

Projects should advance from Technology Readiness Level 2 or 3 to TRL 6 during Phase 1, with successful awardees eligible to compete for Phase 2 funding that pushes to TRL 7. That trajectory — from bench-scale proof-of-concept to pilot demonstration — is the program's core design. DOE is not funding basic research, and it is not funding commercial deployment. It is funding the valley of death in between.

Topic Area 2: Semiconductor-Grade Refining of Gallium, Germanium, and Silicon Carbide ($6 million, deadline June 25). This is the smallest track by dollar amount but arguably the most strategically urgent. The United States currently has zero domestic production capacity for semiconductor-grade gallium. All of it is imported — predominantly from China, which produces over 98 percent of global primary gallium. When China imposed export controls, U.S. chipmakers scrambled for alternative sources and found almost none.

DOE expects to make just 1 to 5 awards in this topic area, with a maximum of $2 million per award. The program targets processes that can refine raw gallium, germanium, or silicon carbide to the purity levels required for semiconductor manufacturing — typically 99.9999 percent (6N) or higher. This is not bulk commodity processing. It is precision chemical engineering at the frontier of materials purity.

Topic Area 3: Direct Lithium Extraction ($23 million across three sub-topics, deadline July 23). The largest track by number of expected awards (13 to 21) targets three flavors of lithium extraction. Topic 3A funds direct lithium extraction from geothermal brines. Topic 3B funds brine pretreatment and polishing technologies. Topic 3C funds exploration and characterization of volcanic geothermal systems that may contain lithium-bearing brines.

The Salton Sea in Southern California alone is estimated to contain enough lithium to supply the entire U.S. battery industry for decades. The challenge is that geothermal brines are hot, acidic, and laden with competing ions that foul conventional extraction membranes. Companies like EnergySource Minerals and Controlled Thermal Resources have been working on DLE technology at the Salton Sea for years, but no commercial-scale facility has yet demonstrated consistent, cost-competitive production. Topic Area 3 aims to accelerate the next generation of extraction, pretreatment, and resource characterization technologies that make geothermal lithium viable.

The Billion-Dollar Pipeline Behind the $69 Million

The Accelerator does not exist in isolation. It is one piece of a critical minerals funding strategy that DOE has been building across multiple offices and authorization streams.

In August 2025, DOE announced its intent to issue nearly $1 billion in critical minerals NOFOs. The first tranche — $355 million across two programs — has already closed. The Mines and Metals Capacity Expansion program put $275 million toward pilot-scale facilities that recover critical materials from coal-based feedstocks and industrial byproducts. The Mine of the Future initiative allocated $80 million to establish proving grounds for next-generation mining technologies, including autonomous drilling, advanced ore sorting, and real-time subsurface sensing.

A separate $500 million Battery Materials Processing and Manufacturing/Recycling NOFO is in pre-release, with DOE having published a Notice of Opportunity but not yet the full solicitation details. When that NOFO drops — likely in the coming weeks — it will represent the largest single critical minerals funding opportunity in DOE history.

Meanwhile, the White House announced a $12 billion Critical Mineral Reserve program through the Export-Import Bank, creating public-private partnerships to secure domestic mineral sources. And the DOE itself has undergone organizational restructuring: the new Office of Critical Minerals and Energy Innovation (CMEI) now consolidates what were previously scattered programs across the Office of Energy Efficiency and Renewable Energy, the Office of Fossil Energy, and the Advanced Manufacturing Office.

All of this means that the $69 million Accelerator is best understood as an on-ramp to a much larger ecosystem. Organizations that establish relationships with DOE through Phase 1 Accelerator awards will be positioned to compete for Phase 2 funding and for the larger NOFOs in the pipeline.

Who Should Apply — and Who Should Not

The Accelerator's 20 percent cost-share requirement is relatively modest by DOE standards (some programs require 50 percent), but it still means applicants need skin in the game. A $2 million award requires $400,000 in matching funds, which can include in-kind contributions but not other federal funding.

Eligible applicants include domestic for-profit entities, universities, national laboratories, nonprofits, and state and local government entities. DOE encourages — but does not require — teaming arrangements that pair technology developers with national lab scientists and end-users who can validate commercial viability.

The strongest proposals will demonstrate three things. First, a clear technology pathway from current TRL to the target TRL, with preliminary data supporting feasibility. Paper concepts will not compete well against proposers who bring lab results, even preliminary ones. Second, a credible cost analysis showing that the proposed process can achieve economic viability at scale — not just technical success at bench scale. DOE is explicitly funding the transition from "it works" to "it works at a price the market will pay." Third, participation in the Critical Materials Collaborative, a DOE-sponsored network that connects awardees with each other, with national labs, and with downstream customers. Participation is mandatory for award recipients.

Companies that should look hard at the Accelerator include materials recycling firms, hydrometallurgical processors, geothermal energy companies with brine access, semiconductor materials startups, and mining technology developers. University research groups with mature technologies ready for pilot-scale demonstration are also strong candidates, particularly when partnered with industry collaborators who can provide cost-share and a path to commercialization.

Companies that should probably pass: those working on early-stage basic research (this program starts at TRL 2-3, not TRL 1), those without U.S. manufacturing presence or plans, and those whose technology addresses non-critical materials even if the processing methods are similar.

The Geopolitical Clock Is Ticking

Secretary of Energy Chris Wright framed the program in blunt terms: "For too long, the United States has relied on foreign nations for the minerals and materials that power our economy." That framing is not rhetorical. China's export restrictions on gallium and germanium have already forced European and American chipmakers to draw down stockpiles, seek expensive alternative sources, and in some cases delay production schedules. The Pentagon's 2025 Industrial Base Assessment flagged critical minerals dependency as one of the top five risks to defense production.

The National Energy Dominance Council — a Trump administration creation — has set aggressive 30-day response timelines for agencies to develop domestic mineral supply strategies. DOE's organizational restructuring and funding pipeline are direct responses to that mandate.

For applicants, the geopolitical context means two things. First, reviewers will reward proposals that credibly reduce import dependency within a defined timeframe — not in theory, but with specific production targets and timelines. Second, the political tailwinds behind domestic mineral production are as strong as they have been in decades, with bipartisan support in Congress that has survived multiple budget cycles. Programs funded under this authority are unlikely to face the clawback risks that have affected other clean energy initiatives.

The staggered deadlines give organizations time to prepare carefully. Topic Area 1 closes May 29. Topic Area 2 closes June 25. Topic Area 3 closes July 23. Full application details, including the informational webinar recording from April 16, are available on the DOE CMEI website. For organizations evaluating whether the Accelerator fits their technology and team, Granted can help identify the right topic area and build a competitive proposal before the deadlines arrive.
