Meine Electric Iron-Air Battery

Meine Electric is a deep-tech startup based in Chennai, India, founded in 2023 by Priyansh Mohan and Stuti Kakkar according to a July 2026 press release. It develops iron-air batteries for long-duration energy storage on grids and in industry, with products made in India.

The battery stores energy through a reversible rusting reaction of iron, air and water. Per the company, it charges in about 6 hours and discharges for 12 to 18 hours, with no thermal runaway risk. It targets utilities, independent power producers, microgrid operators and commercial and industrial captive power users.

• Iron-air chemistry: reversible rusting of iron with air and water stores energy.
• Long duration: 12 to 18 hours of discharge for microgrids and captive power.
• Fast charging: about 6 hours to full charge.
• Inherent safety: no thermal runaway.
• Independent validation: CES Battery Laboratory tested cells on a 6-hour charge and 18-hour discharge cycle.

Shifting rooftop or ground-mounted solar output to evening hours for factories in Vietnam. Overnight supply for microgrids on islands or remote sites. Backup and peak shaving for commercial and industrial captive power.

Long discharge of 12 to 18 hours for shifting solar power into the night.

Fast charge of about 6 hours, per company claims.

No thermal runaway, a safety advantage over many lithium systems.

Iron-based, locally sourced materials intended to keep cost low.

Rapid solar growth in India and Southeast Asia raises demand for storage that covers evening and overnight demand. Iron-air and other non-lithium chemistries compete on cost per kWh for long durations. Vietnam and neighbours face similar solar curtailment and evening peak issues.

Founded 2023 in Chennai per a July 2026 press release (the website does not state it). Raised a US$750,000 pre-seed round reported in 2026. Pilot-stage technology; containerised systems targeted for 2027. Claims are company statements.
