Nth Cycle DOE Grant of Up to $100M Doubles Battery Refinery Plan

A big federal bet on a small Massachusetts refiner

Nth Cycle is a battery-recycling and critical-minerals startup based in Burlington, Massachusetts. The U.S. Department of Energy picked the company to negotiate a grant of up to $100 million toward a black-mass refinery in the Southeast, which the company calls Project SHIELD.1 The Boston Globe reported that Nth Cycle has about 50 employees, already runs a plant in Ohio, and has talked about opening another site in the Netherlands.1 The new refinery is meant to process up to 24,000 metric tons of black mass a year. It could support more than 800 construction jobs and over 50 permanent ones, and it could be running as soon as 2029.1

Black mass is the powder left over when spent lithium-ion batteries are shredded. It contains nickel, cobalt, lithium and other metals that can be recovered, but only after further refining.2225 Project SHIELD would turn it into high-purity nickel mixed hydroxide precipitate (MHP) and battery-grade lithium carbonate. The intended buyers include makers of defense systems, AI data center backup power, electric vehicles and grid storage.2627

The Globe called the award a rare piece of good news for a local climate-tech startup asking the Trump administration for help.1 Of all the coverage, that line explains the most about why this deal stands out.

"Up to" is doing a lot of work

Headlines have described the money in different ways, and the differences matter. Some trade outlets said Nth Cycle "received" or was "awarded" $100 million.2229 More careful reports describe a selection to begin negotiations, not a finished award.1624 One analysis spelled out what that means. A DOE selection starts talks over milestones, compliance terms and payment schedules. Final approval depends on those talks going well, and a selection can be withdrawn.25

The precise version is the right one. Nth Cycle was one of seven projects selected on August 20 to share about $500 million in possible federal support. The money comes from the third round of DOE's Battery Materials Processing and Battery Manufacturing and Recycling programs.24 The award is still a ceiling, not cash in hand, and that matters for a company whose finances are tight (more on that below).

Accounts of the location also differ. The Globe and an industry newsletter named South Carolina.122 A recycling trade publication described the site as still undecided somewhere in the Southeast.30 Industrial Info's reporting fits both versions: South Carolina is the target state, but a specific site is still being chosen, and construction may not begin until next year.22

Why critical minerals win when climate tech loses

The main story here is about framing. Under this administration, Massachusetts climate-tech companies have mostly faced federal pullback. Sublime Systems, a clean-cement company in Somerville, dropped plans for a $150 million factory in Holyoke after the administration pulled an $87 million grant.11 Offshore wind, once expected to be a major industry for the state, has been badly hurt by supply-chain problems and political attacks from Washington.11

Nth Cycle got through by presenting itself as a national-security company, not a climate company. CEO Megan O'Connor thanked the administration for treating domestic recovery of critical minerals as a security matter.1 When the selection was announced, she said domestic refining capacity is what separates having access to critical minerals from having secure access to them.24 DOE used similar language, describing Project SHIELD as a way to fill a gap in midstream processing.24

Trade policy supports that pitch. The Commerce Department recently put a one-year ban on black mass exports. That makes domestic refining capacity more urgent, because the material can no longer simply be shipped abroad.27 One newsletter summed up the policy logic in its headline: Washington bans the export, then pays to build the domestic alternative.26 The administration's own framing points the same way. Energy Secretary Chris Wright recently highlighted advances in critical materials alongside fusion and supercomputing as pillars of energy security.7

The takeaway for other climate-tech founders is uncomfortable but clear. In the current federal climate, the same technology can get funded or ignored depending on whether it is described in terms of emissions or supply chains. Nth Cycle's electrochemical process does have environmental advantages. The Globe reported that it uses electricity instead of the traditional chemical methods, which are less efficient, cost more and pollute more.1 But the federal case for the project rests on breaking dependence on China, not on cleaner processing.

The money unlocked a bigger plant and new partners

The DOE selection changed the project's size. Nth Cycle originally planned SHIELD around a roughly $1.1 billion, 10-year offtake deal with commodities trader Trafigura. That deal covered about 12,000 metric tons of black mass, with operations targeted for 2028.24 After the federal selection, the company doubled planned capacity to 24,000 tons, started looking for a larger site, and pushed the start date to 2029.2430

Glencore came next. In September, Nth Cycle signed a binding term sheet with the Swiss commodities giant for a 10-year offtake estimated at more than $1 billion, based on second-quarter 2026 price forecasts.28 Glencore would supply all of SHIELD's black mass through its U.S. shredding operations. It would also buy MHP and lithium carbonate, and look at whether one of its existing U.S. sites could speed up construction.23 With that deal, Nth Cycle says it has binding term sheets covering all of its projected feedstock and offtake needs for the refinery.28 The two companies are aiming to sign definitive agreements by the end of 2026.23

The Trafigura deal is described inconsistently. Some coverage calls it a term sheet, while one investor-focused analysis calls it a letter of intent and notes that an LOI is not binding.36 Either way, two of the world's largest commodity traders now sit on both the supply and sales sides of the project. Few startups get that kind of backing, and it is probably the strongest commercial evidence that the plant could work.

A public listing with real risk

Nth Cycle is also trying to go public. In July it agreed to merge with Kensington Capital Acquisition Corp. VI, a blank-check company (SPAC), at an implied enterprise value of about $585 million. The combined company would trade on the NYSE under the ticker NTH.37 The deal could bring in up to $230 million from Kensington's trust account, depending on how many shareholders redeem, plus up to $100 million from a stock sale to private investors (a PIPE). Only $40 million of that PIPE is committed so far.31 Closing is expected in the fourth quarter of 2026.34

The company's financial statements show why it needs the deal. At the end of 2025, Nth Cycle had $8.2 million in cash and an accumulated deficit of $63.8 million. The merger filing raised substantial doubt about whether it can keep operating for the next 12 months.32 For the deal to close, at least $75 million must be available from the trust after redemptions and the PIPE combined.32 One analysis noted that redemption rates above 80 percent have been common in recent SPAC deals, which could shrink the headline trust figure to a fraction of $230 million.33

That changes how the DOE selection should be read. The grant is not just a construction subsidy. It also reassures SPAC investors who are deciding whether to keep their shares or cash out. O'Connor's comment to the Globe that it "will be a fun fall" hints that the merger vote and the grant negotiations will play out around the same time.21 Nth Cycle also joins a wider rush of critical-minerals companies going public through SPACs this year. That list includes Controlled Thermal Resources' $4.7 billion deal and ProLogium's $3.8 billion merger.37

What it means for Massachusetts

O'Connor called the DOE selection a "full circle moment."1 Nth Cycle began at Oak Ridge National Laboratory in Tennessee with DOE funding and moved to Massachusetts in 2020.1 There is a catch for the state, though. A company based in Massachusetts is building its flagship refinery in the Southeast, and the jobs will mostly go there too.

That happens as Governor Maura Healey tries to make climate tech the state's next big industry. Her plan is modeled on the $1 billion, 10-year push that helped build up life sciences.11 The state is behind on that $1 billion target, and funding for its Massachusetts Clean Energy Center (MassCEC) has dropped from $30 million a few years ago to $8 million this fiscal year.11 The state has handed out smaller amounts, including $27.2 million in climate-tech tax incentives across 18 companies.16 MassCEC's head acknowledged that some projects need money on a scale only the federal government can provide.11

Nth Cycle fits that description. It has the right story for Washington, partners in Glencore and Trafigura, and a path to the public markets. Whether it becomes a success depends on converting a grant selection and term sheets into signed contracts, a closed merger and a working refinery by 2029. For other climate-tech startups, the main lesson is about framing: right now, federal money is going to projects pitched as supply-chain security, not as climate solutions.
