US Signs First Commercial Cobalt Refinery Deal, Targeting China’s 75% Processing Monopoly
EVelution Energy's $850 million Mitsui offtake agreement marks the first attempt to build domestic cobalt refining capacity as IRA compliance deadlines loom and battery demand accelerates.
EVelution Energy secured an $850 million binding offtake agreement with Japanese trading house Mitsui on 28 April for the first commercial-scale cobalt refinery in the United States, directly challenging China’s control of 75% of global refined cobalt production.
The five-year deal commits Mitsui to purchase up to 3,000 metric tons of contained Cobalt annually from EVelution’s planned Yuma, Arizona facility — representing 40% of estimated US cobalt demand when fully operational. Construction begins early 2027 with targeted completion by end of 2029, according to Business Wire. The timeline positions the facility to meet surging battery demand as the Inflation Reduction Act’s domestic sourcing requirements take effect.

The Supply Chain Arithmetic
China’s refining dominance vastly exceeds its mining footprint. While the Democratic Republic of Congo controls 70% of mined cobalt reserves, China processes three-quarters of global output — 140,000 metric tons in 2022, per the Institute for Energy Research. This processing chokepoint creates geopolitical leverage independent of resource ownership.
The gap presents an immediate problem for US battery manufacturers. The IRA requires 80% of battery mineral value be sourced domestically or from free trade agreement countries by end of 2026 for EV tax credit eligibility. Current US cobalt import dependency sits at 77% from non-FTA sources, according to the Ifri Energy & Climate Center. Without domestic refining capacity, battery makers face a binding constraint on scaling production under IRA incentives.
Battery demand for cobalt reached 150 kilotons in 2023, representing 70% of total consumption, data from the International Energy Agency shows. Benchmark Mineral Intelligence forecasts global demand will increase almost 80% over the next decade, with EVs accounting for 84% of total cobalt consumption by 2030.
“When Mitsui — one of the most sophisticated trading houses in the world — signs an offtake agreement valued at approximately $850 million, that is not a bet on the future. That is a verdict on the present.”

Allied Network Economics
Mitsui’s commitment signals commercial viability beyond strategic rationale. The Japanese trading house’s willingness to lock in an $850 million multi-year offtake reflects both demand certainty in allied battery supply chains and confidence in EVelution’s technical execution. Japan lacks domestic cobalt sources and currently relies on Chinese refining capacity for its battery manufacturing base.
The facility’s design targets environmental compliance alongside production economics. EVelution plans to generate its own solar power, recycle 70% of process water, and operate without on-site tailings storage, per Business Wire. The project is expected to generate more than $750 million in economic activity and create 3,300+ jobs in Yuma County over its operational life.
The 2027 Compliance Window
EVelution’s 2029 timeline creates an 18-month vulnerability window. The IRA’s 80% domestic sourcing threshold becomes binding at end of 2026, but the first US commercial cobalt refinery won’t be operational until three years later. US battery manufacturers must either secure cobalt from existing FTA partners, accept reduced tax credit eligibility, or delay production scaling.
China has already demonstrated willingness to weaponise critical mineral processing. Graphite export controls implemented between 2023-2025 previewed the playbook. Cobalt refining presents a structurally similar chokepoint: China controls processing capacity far exceeding its mining share, and demand growth is concentrated in a sector (EVs) where geopolitical competition intensifies.
- US battery makers face a binding cobalt sourcing constraint between end-2026 IRA compliance and 2029 domestic refining capacity
- Allied sourcing networks (Japan-US) are being constructed in parallel to Chinese processing dominance, not as replacement
- The $850 million Mitsui commitment validates commercial economics beyond strategic subsidy dependence
- 2027-2029 period represents maximum vulnerability to potential Chinese export restrictions on refined cobalt
What to Watch
Track whether additional US battery manufacturers pre-commit to EVelution’s output ahead of 2029 completion. The 3,000 metric ton annual capacity represents 40% of estimated US demand — insufficient to eliminate import dependency, but enough to break the processing monopoly if additional facilities follow. Construction timeline adherence through 2027-2028 will signal whether the US can execute critical mineral strategy at commercial scale.
Monitor Chinese policy responses. Beijing’s historical pattern has been to accelerate downstream capacity buildout when faced with supply chain diversification threats. Any moves to restrict refined cobalt exports or preferentially supply Chinese battery makers would validate the strategic rationale for domestic refining investment and likely accelerate allied sourcing network development.
The gap between IRA compliance deadlines and domestic refining capacity defines the next two years. Battery manufacturers either navigate the shortfall through FTA partnerships or absorb reduced tax credit economics. Either way, the first US commercial cobalt refinery deal marks the beginning of supply chain reconfiguration, not its completion.
