Meine Electric Advances Iron-Air Battery Technology for Long-Duration Energy Storage
Meine Electric is developing an iron-air battery system capable of 16- to 24-hour energy storage cycles, targeting deployment costs under $40 per kWh. This technology addresses energy storage challenges in India amidst rising demand for renewable energy solutions.

Meine Electric, founded in 2022, is innovating a utility-scale iron-air battery system designed for long-duration energy storage. The company aims for a deployment cost below $40 per kWh, significantly lower than lithium-ion alternatives priced at $110-$120 per kWh.
Notably, its technology exploits rusting to release energy, while proprietary membranes enhance efficiency and reduce costs. The startup has secured pilot orders with both private and public sector power producers and is attracting interest from commercial entities seeking to reduce electricity costs.
Although iron-air batteries return only 55-60% of energy input, their low production costs, derived from abundant materials, position them favorably in the renewable energy market. As India faces curtailment issues with renewable power, this technology could enhance the utilization of solar and wind resources.
