Every mapped input in the Form Energy supply chain

37 nodes, grouped by supply-chain tier. Sourcing risk describes where an input is mined or refined; it is not a FEOC determination for Form Energy.

Producer (1)

Input	Origin	Sourcing risk	Basis
Form EnergyForm Factory 1, Weirton, West Virginia (former Weirton Steel site)	United States	No known risk factor	Iron-air 100-hour long-duration battery. Active materials are iron, water, and air, deliberately chosen to avoid imported strategic minerals. Assembly is US-based.

Component (9)

Input	Origin	Sourcing risk	Basis
Iron Electrode (Negative Electrode)Weirton, WV	United States	No known risk factor	Reversible-rusting iron electrode; the storage medium. Made from iron powder produced in-house via low-temperature alkaline electro-reduction of iron ore.
Air Electrode (Positive / Bifunctional Oxygen Electrode)Weirton, WV	United States	Elevated sourcing risk	Gas-diffusion electrode enabling ORR (discharge) and OER (charge). Combines catalyst, conductive carbon, and PTFE binder; several inputs are China-refined.
Alkaline Electrolyte (Aqueous KOH/NaOH)Weirton, WV	United States	No known risk factor	Water-based non-flammable alkaline electrolyte. Potassium/sodium hydroxide dissolved in deionized water; ionic medium for the cell.
Cell Stack / Battery ModuleWeirton, WV	United States	No known risk factor	10-20 meter-scale cells stacked in a water-filled module. Integrates iron and air electrodes, separators, and electrolyte.
Steel Enclosure & Module HousingUSA	United States	No known risk factor	Steel tank/housing holding electrolyte and cell stack. Sourced from North American steel; low-cost commodity input.
Air Handling / Water Management SystemUSA	United States	Elevated sourcing risk	Blowers, pumps, and airflow controls that feed oxygen and manage electrolyte/water balance. Motors and controls may include imported subcomponents.
Power Electronics / Inverter (Balance of System)USA	United States	Elevated sourcing risk	DC-AC conversion and grid interface. Power inverters commonly depend on globally sourced semiconductors and magnetics.
Battery Management & Controls (BMS)USA	United States	Elevated sourcing risk	Monitoring, balancing, and safety controls. Depends on semiconductors/PCBs with globalized (partly Asian) supply.
Separator / Cell MembraneUSA	United States	Elevated sourcing risk	Ion-permeable separator between electrodes in the alkaline cell. Polymer separator supply is globalized.

Processing and refining (6)

Input	Origin	Sourcing risk	Basis
Nickel Refinery (Sulfate / Electrolytic)	China	Covered nation	FEOC chokepoint: pyrometallurgy + electrolytic refining of nickel to battery-grade sulfate is China-dominated even for Indonesian ore.
Cobalt Refinery	China	Covered nation	FEOC chokepoint: the majority of DRC cobalt is refined in China into battery-grade chemicals.
Chlor-Alkali Plant (KOH Electrolysis)	United States	No known risk factor	Membrane-cell electrolysis of KCl brine into KOH. US and Western Europe have ample chlor-alkali capacity.
Pellet / DRI Processing PlantMinnesota / Ohio (HBI)	United States	No known risk factor	Beneficiation and pelletizing of taconite into DR-grade pellets. Domestic processing keeps the iron chain clean.
Copper Smelter / Refinery	China	Covered nation	FEOC chokepoint: China holds ~50% of global copper smelting/refining capacity; refined-copper origin is often Chinese.
Polysilicon / Silicon Metal Refiner	China	Covered nation	FEOC chokepoint: China dominates silicon metal and polysilicon refining feeding semiconductor and power-electronics chains.

Semiconductors / Silicon Wafers (Power & Control)	Taiwan	Elevated sourcing risk	Chips for inverter and BMS. Wafers fabbed in Taiwan/US/Korea; some polysilicon and assembly steps touch China.
Refined Copper (Wiring / Busbars)	United States	Elevated sourcing risk	Conductors, busbars, motor windings. Copper refining is globally distributed with significant Chinese smelting share.

Mine and extraction (6)

Input	Origin	Sourcing risk	Basis
Nickel Mine (Laterite / Sulfide Ore)	Indonesia	Elevated sourcing risk	Primary nickel extraction. Indonesia is the dominant mined-nickel source; much output is processed by Chinese-owned operations.
Cobalt MineKatanga Copperbelt	Democratic Republic Of Congo	Elevated sourcing risk	~70% of mined cobalt originates in the DRC, largely as a copper by-product.
Potash Mine (Sylvinite / KCl)Saskatchewan potash basin	Canada	No known risk factor	Underground/solution potash mining for KCl. Canada is the leading allied potash producer.
Iron Ore Mine (Taconite)Mesabi Range, Minnesota	United States	No known risk factor	Taconite extraction for DR-grade pellets. Core of the domestic, FEOC-clean iron supply.
Copper Mine	Chile	No known risk factor	Primary copper extraction. Chile and the US are leading allied copper sources.

Sources and methodology

Research-based supply-chain map compiled from public sources - not an audited bill of materials. Tiers reflect the standard industry structure for this product. Sourcing risk on a node describes where that input is typically mined or refined; it is not a FEOC determination for Form Energy, and it is not a screening result for the node itself unless a federal listing is cited against it. Verify against primary documentation before making a compliance determination.

Common questions

Where does Form Energy source the inputs in this product?: This map traces 37 inputs across 7 countries, including 12 mines and refiners. It is compiled from public sources and is not an audited bill of materials.
How much of the Form Energy supply chain sits in a covered nation?: 9 of 37 mapped inputs are sited in a covered nation (China, Russia, Iran or North Korea) or named on a federal restricted-party list. A further 10 carry elevated sourcing risk without either basis.
Is Form Energy itself a Foreign Entity of Concern?: No federal designation found. Form Energy is not named on any of the 3 federal restricted-party lists screened for this record (DOD Section 1260H, BIS Entity List, OFAC SDN List), and the United States is not a covered nation under the FEOC rules. Sourcing risk in this map describes where inputs are mined and refined and is a separate question from the company's own federal screening.
