4. Technology & Innovation

Technology Stack

Form Energy specializes in developing ultra-long duration energy storage systems centered around its proprietary iron-air battery technology, dubbed "reversible rust" technology.
Core platforms and technologies:
Iron-air battery systems: These batteries leverage the natural process of rust (iron oxidation and reduction) to store and discharge energy. They are designed to store electricity for up to 100 hours, significantly longer than the typical four-hour duration of lithium-ion batteries. The technology uses abundant, low-cost materials: iron, water, and air, eliminating the need for rare-earth minerals. The system is cost-effective, with claims of approximately one-tenth the cost of lithium-ion batteries per unit of energy stored. It also exhibits strong inherent safety with no thermal runaway or fire propagation, as demonstrated by UL9540A safety testing in 2024.
Formware: A grid modeling toolkit that captures the dynamics of decarbonizing grids, assisting potential customers in understanding and integrating Form Energy's long-duration storage solutions.

Scientific methodologies

The core scientific principle is the reversible rusting of iron. In discharge mode, the battery "breathes in" oxygen from the air, converting iron metal to rust and releasing electrons to generate electricity. To recharge, an electrical current is applied to convert the rust back into metallic iron, and the battery "breathes out" oxygen. This cycle is durable and repeatable.

Technical capabilities

Form Energy's iron-air battery system utilizes a modular and scalable design. Each battery module contains a stack of individual battery cells filled with iron and air electrodes, as well as a water-based, non-flammable alkaline electrolyte. These modules are grouped in environmentally protected enclosures, which are then grouped into megawatt-scale power blocks. These systems can be sited anywhere, including urban areas, to meet utility-scale energy needs.

Proprietary developments and patents

Form Energy holds several patents related to its energy storage systems:
"Methods for power storage in a power network" (Patent number: 12191702, Date of Patent: January 7, 2025).
"Stack of electric batteries including series of fluidly connected unit cells" (Patent number: 12237548, Date of Patent: February 25, 2025).
