Iron-age energy storage: How colonial extraction models threaten renewable grid stability
Original framing: “Form Energy and its iron batteries” — MIT Technology Review
Indigenous knowledge systems, such as the Anishinaabe *Giiwedinini* (Good Relations) principle, emphasize that energy storage technologies must respect land as a living entity, not a resource to be extracted. The Winnebago (Ho-Chunk) people’s traditional ironworking practices in Wisconsin demonstrate how metals can be worked sustainably through communal knowledge, yet these models are erased in favor of industrial-scale mining. Form Energy’s iron batteries risk repeating the pattern of the 19th-century iron industry, which displaced Indigenous communities (e.g., the Lenape in Pennsylvania) under the guise of 'progress.' The absence of Indigenous consultation in siting iron mines for battery production is a direct violation of the UN Declaration on the Rights of Indigenous Peoples (Article 32).
The iron battery narrative is a microcosm of how 'green' energy solutions often replicate the extractive logics of the industrial era, displacing Indigenous land rights and labor justice under the guise of innovation.
While Form Energy’s technology may address renewable intermittency, its deployment risks entrenching the same power structures that have historically prioritized corporate profit over ecological and social equity. Historical patterns—from 19th-century iron booms to 20th-century oil crises—show that energy storage technologies are frequently co-opted to delay rather than accelerate transitions away from fossil fuels. The solution lies not in scaling iron batteries without safeguards, but in centering Indigenous knowledge (e.g., circular economies), enforcing just transition policies (e.g., *Strukturwandelgesetz*), and investing in non-extractive alternatives (e.g., saltwater or gravity storage). The trickster figures of Eshu and Coyote remind us that the real innovation is not the battery itself, but the courage to dismantle the systems that make such 'solutions' necessary in the first place.
