Funding Fuels Advancement in Energy Storage Solutions
Mana Electric, positioning itself as APAC's first iron-air long-duration energy storage (LDES) innovator, has secured $750,000 (approximately ₹6.7 crore) in a pre-seed funding round. The investment was led by Antler and saw participation from Rebalance, Venture Catalysts, gradCapital, and AIC-AU Incubation Foundation, which is hosted by Anna University. Angel investors, including industry veteran Alexander Hogeveen Rutter, also contributed to the round, signalling robust backing for the company's vision.
Accelerating Iron-Air Battery Technology Development
The freshly acquired capital is designated to propel Meine Electric's progress from laboratory-scale prototypes to fully pilot-ready iron-air battery systems. Founded in 2023 by Priyansh Mohan and Stuti Kakkar, the startup claims its proprietary iron-air battery technology can achieve a levelised cost of storage below $0.05/kWh (approximately ₹4/kWh). Iron-air batteries, which use abundant materials like iron, air, and water, operate via a reversible rusting process for energy storage. This technology is positioned as a more sustainable and cost-effective alternative to lithium-ion batteries for long-duration storage needs. The company operates from a 5,000 sq ft facility in Chennai, which is being prepared for pilot production.
Enhancing Grid Stability with Advanced LDES
Mana Electric's iron-air battery technology is designed to offer 16-24 hours of energy storage, with a claimed full charge within 8 hours, aligning with typical solar surplus windows. This capacity aims to provide Round-the-Clock (RTC) renewable energy coverage, a critical component for grids aiming for high renewable penetration. Unlike many global competitors, Meine Electric states its technology supports faster charge and discharge cycles, facilitating integration with solar-heavy grids.
Strategic Importance in India's Energy Transition
The development of LDES is becoming increasingly crucial as India aims to integrate a higher percentage of renewable energy into its grid. Alexander Hogeveen Rutter, Manager at Third Derivative, noted the growing need for LDES to replicate the benefits of conventional generation as renewable penetration rises. He highlighted that solutions like Meine Electric's are becoming essential for off-grid applications and will be increasingly vital at the grid scale. Meine Electric plans to develop multi-kilowatt grid-connected prototypes and larger pilot units, with a goal to deliver containerized iron-air battery systems by 2027.
Market Context for Long-Duration Energy Storage
Long-duration energy storage is pivotal for balancing the intermittent nature of renewable sources like solar and wind power. As India targets 500 GW of non-fossil fuel capacity by 2030, the demand for storage solutions to ensure grid stability and reliable power supply is escalating. While lithium-ion batteries are prevalent for shorter durations, LDES technologies like iron-air are gaining traction for their potential to provide cost-effective, multi-day storage. Iron-air batteries are considered advantageous due to their use of abundant, low-cost materials, mitigating supply chain risks associated with rare earth minerals. Meine Electric aims to leverage this by offering a solution that can potentially achieve a levelized cost of storage significantly lower than current lithium-ion offerings.
